Citrix XenServer gives you everything that you need to manage, integrate and automate a virtualized server infrastructure which consolidates a physical server's computing power into multiple virtual machines and administers their performance and use, all emulating as a standard server. When block storage such as iSCSI or Fibre Channel is used with XenServer, thin provisioning enables XenServer to dynamically allocate storage resources as capacity demands increase. Thin Provisioning must be enabled in order for XenDesktop local caching to work properly. 5 and later uses GFS2 to provide the ability to set up thin provisioning with a shared block storage device. 0 with Thin Provisioning is utilised and that 2 images will be required for 2 desktop types, power users and normal users. Thin Provisioning allows the administrator to present more storage space to the VMs connecting to the Storage Repository (SR) than is available on the SR. Select XenServer Virtual Machine Storage 7. In the calculations below I have assumed that XenServer 6. Van Vugt: What you’re looking at is mainly hardware-specific versions of XenServer. During installation of XenServer, select "Enable thin provisioning (Optimized storage for XenDesktop)"; see Fig. The Provisioning Server streams the contents of the vDisk to the target device on demand, in real time. Conslusion: The main question is which is the best solution. Since we are installing from local CD/ISO select Local media as source and press OK to continue. Press Ok to continue. com/article/CTX129387 ). Citrix XenServer gives you everything that you need to manage, integrate and automate a virtualized server infrastructure which consolidates a physical server’s computing power into multiple virtual machines and administers their performance and use, all emulating as a standard server. While on the topic of storage, this is something I wanted to blog about earlier but never got around to.

This feature Next I prepared a second server. If there is a large difference between the amount of data stored by the VM and the space consumed by the virtual disk file it could be worth to reclaim the space. One of these is in charge of running the rest of the system, and is known as domain 0, or dom0. While VMware does not support Asset Management and Configuration Mapping, XenServer does support these two management features in addition to Thin Provisioning but does not support key features such as Dynamic Resource Allocation, Failover, and Enabling IntelliCache involves configuration on the XenServer side and on the XenDesktop side. Tutorials. included in XenServer, and are hosted on a NetApp device running a version of Data ONTAP 7. Messages Hide implicit. With thin provisioning, no space is lost because the “spare” 370 GB is able to be used for other purposes. 5 with virtualization adoption by leveraging deduplication and thin provisioning to remove much of the high costs found On Provisioning Server console select a device to use for maintenance and put in maintenance mode,(it should also be in maintenance mode on XenDesktop console. Set a good *XENSERVER_ROOT* password. Understanding thick and thin provisioning c). You should create the pool first with both of your hosts added then add your SR. If you installed Xenserver you can see an option with the name "enable thin provisioning optimized storage for xendesktop" and it is not mean Citrix that you thinking. the enterprise. You create the size VM Disk that you want and it will only use the actual storage on the backend. read XenServer configuration from a XML config file (url, username, passwort) 2. Note: XenServer treats all disks selected in this screen as a single SR. xe sr-create host-uuid=ba3d140c-3de5-499b-b831-7c40d82958a9 content-type=user type=lvm device-config:device=/dev/sdb shared=false name-label="Local storage 2" sm- config:allocation=thin Third option Enabling IntelliCache involves configuration on the XenServer side and on the XenDesktop side. If you are installing from CD it is recommend to verify the media, otherwise you can skip. connect to XenServer or Poolmaster 3.

Thin provisioning for block storage. XenServer Pools (clusters) require a shared Storage Repository (SR) so this rules out thin provision with block storage. 5. Here’s instructions on using NTLMv2. xe sr-create host-uuid=ba3d140c-3de5-499b-b831-7c40d82958a9 content-type=user type=ext device-config:device=/dev/sdb shared=false name-label=”Local storage 2″ 10. I created a storage repository with thin provisioning a while ago (thus it uses ext) as shown here: Now when I go to /dev/cciss (since I use an HP raid controller) I only get: Thin provisioning for shared block storage - GFS2 (Enterprise Edition) XenServer makes thin provisioning available to customers using block-based storage accessed through iSCSI software initiator or Hardware HBA. The XenServer EqualLogic Storage Adapter allows thin volumes to be created from the XenCenter interface or using XenServer CLI, thus optimizing storage requirement and simplifying storage deployment for virtual machines. Would this be able to support Thin-Provisioning our is EXT4 the only hope for Local SRs larger than 2TB? XenServer uses a clustered LVM system to store VM images on iSCSI and Fiber Channel volumes and does not support over-provisioning in the hypervisor. First, you need to be on XenServer 5. Third option: Create a EXT storage repository with thin provisioning support and direct access to the vhd files. Network interface bonds d). 12. 6 September 27, 2018 October 5, 2018 Citrix Citrix Problem scenario 1: All hosts can ping each other, but creating a cluster is not possible. This is now managed with the Windows Printer Management Role in Windows Server 2008 R2 or through XenApp PowerShell Cmdlets.

Storage A. XenServer networking architecture B. XenServer uses a clustered LVM system to store VM images on iSCSI and Fiber Channel volumes and does not support over-provisioning in the hypervisor. Support for 64 hosts per pool, thin provisioning on Thin provisioning virtualizes storage capacity in the same way virtualization virtualizes server capacity. This is due to an issue in Integrated StorageLink (iSL) when using NetApp storage arrays, which incorrectly configures volumes for thin provisioning. Enabling IntelliCache involves configuration on the XenServer side and on the XenDesktop side. 6 enhances the scalability of your virtual infrastructure with thin provisioning with block storage. XenServer pools that use GFS2 to thin provision their shared block storage are clustered and behave differently to pools that use shared file-based storgae or LVM with shared block storage. XenServer storage architecture; Understanding thick and thin provisioning; Storage locations; File based and block based storage; Storage multipathing; XenServer Intellicache; XenServer in-memory read caching; XenApp and XenDesktop Provisioning enhancements ; Module 8: High Availability XenSource uses "very simple scripts" to activate NetApp tools such as data snapshots, cloning, replication, back-up and thin provisioning via the XenCenter management console. While it cannot communicate with vCenter Server, it does virtualize servers with options like thin provisioning. XenServer installation post-script. Disabling thin provisioning on a volume will fully allocate the volume size from free pool space (the reported size and the volume reserve will be the same). Skip verification of the installation media. Use a password which you don’t mind being plain-text readable to anyone who has root access to this system. LVHD is the new default type of SR since version 5. LVM thin provisioning - Using thin provisioning, you can manage a storage pool of free space, known as a thin pool, which can be allocated to an arbitrary number of devices when needed by applications. 6 service pack 2 or newer. We must make sure, though, that we adequately monitor the system to stop that undersupply becoming an issue. 1. This option will change the default local storage type from LVM to EXT3. I see that there is plans to have ZFS support in the future. Select ‘Local media’ SANOS is a comprehensive data management system that ensures your business-critical workload go smoothly with consistent performance. Thick Provisioning 6. If you choose to use 100% of this disk, I would personally go with ext3: http://www. Set VM storage to only sdb, and enable thin provisioning: Select local media as the installation source. Essentials for XenServer, and are hosted on a NetApp device running a version of Data ONTAP 7. If you have already installed XenServer and you want to enable thin provisioning on a new drive that is adding, you need to use the CLI. 1.

XenServer storage architecture b). Multiple storage can be defined for one single slave server. It maximizes the storage usage efficiency and eliminates the time of administrative tasks. Thin Provisioning Unavailable Microsoft does not currently provide tools to transfer VHD files to Hyper-V with sparse/thin/dynamic provisioning; you must convert the disks from a live VM using Microsoft Virtual Machine Converter, described here. Students with limited or no XenServer experience will gain an understanding of what is required to implement and maintain the components of a XenServer enterprise solution. Thin provisioning allocates storage space as needed. I already have 2 clients who has 5GB storage each. Xenserver will now boot into the installation, select your keyboard layout. I tried some suggestions like CTX120865, but this is not working on Xenserver 7. Unlike thin-client technology, processing takes place on the target device. The first step occurs during the installation of XenServer itself, where you select “Enable thin provisioning (Optimized storage for XenDesktop)”. 1. 2 VM. XenServer storage architecture; Understanding thick and thin provisioning; Storage locations; File based and block based storage; Storage multipathing; XenServer Intellicache; XenServer in-memory read caching; XenApp and XenDesktop Provisioning enhancements ; Module 8: High Availability XenServer requires at least two separate physical x86 computers: one to be the XenServer host and the other to run the XenCenter application. Citrix XenServer forums are full of the posts with feature requests to add a support for disks bigger than 2TB, but all of them are either XenServer storage architecture Understanding thick and thin provisioning Storage locations File based and block based storage Storage multipathing XenServer Intellicache XenServer in-memory read caching XenApp and XenDesktop Provisioning enhancements Cart. 0 (rio) Unique identifier/object reference. Let's start with XenServer. There are many locations from which XenServer itself can be installed. Do not install any supplemental packs. XenServer physical connectivity; Storage. This means that the storage requirements are significantly higher in XenServer compared to Hyper-V. In the Admin Panel you can now define the Storage for slave servers. 5 host After I described how to convert an existing local XenServer storage repository to support thin provisioning I’m now going to show you how you can add an additional local disk to your XenServer host. Set the installation destination to sda. XenServer 7. Virtual network types c). The target device behaves as if it is running from its local drive. Thin provisioning is a mechanism that applies to large-scale centralized computer disk-storage systems, SANs, and storage virtualization systems. 1. Networking A. Thin Provisioning Performance w/ Nutanix: When running ESXi, Nutanix runs NFS datastores and supports thick provisioning via the VAAI-NAS Space reservation primitive as discussed in this post. 11. 6 or greater. I created 2 SR's as seen below. org Xenserver 6 – Create an Addtional Local Storage Respository with Thin Provisioning Support July 18, 2012 January 5, 2015 / Christopher Paquin So recently I deployed 3 XenServer 6 hosts with local storage only. Storage locations How to Configure Citrix XenServer 6. > If XenServer try to install on Virtual Machine than you will get the following screen. A client was trying to setup a lab of HP T610 thin clients to stream Windows 7 from Citrix Provisioning Services 6. Set VM storage to only sdb, and enable thin provisioning: Select local media as the installation source. Thin vs. I created a PowerShell script which handles the sysprep from your helper machine. First, you need to be on XenServer 5. k. Thin provisioning optimizes the utilization of available storage by allocating disk storage space to VDIs as data is Thin Provisioining in XenServer: Thin provisioning is a method by which the hypervisor can virtually allocate all of the storage assigned to a virtual machine while only physically allocating the space that is actually required by the virtual machine. (thin provisioning for snapshots - LVM) Rootfs (nearly read-only) Crypted var Storage Repository (thin provisioning for disks - EXT) Crypted var2 Crypted swap tmp (ram) Stock Xenserver Disk Layout Modified Xenserver Disk Layout Disk Solution The storage team has provisioned 500 GB of storage space on a NetApp SAN to be used for the XenServer storage repository. Type multipath and this will let xen server knows that multipath is enable for root disk as this server boot from SAN. Go to Xenserver and boot the vDisk from the Maintenance device, install or remove applications, add patches, and complete any other necessary updates, then shutdown the Maintenance device. XenServer 설치. XenServer physical connectivity VII. org/blog/2010/06/20/xenserver-5-6-thin-provisioning-with-ext3/ Citrix XenServer and VMware vSphere serve as the hypervisor, Citrix Provisioning Services streams multiple desktops to the hypervisor, and Citrix XenDesktop Desktop Delivery Controller manages desktops and facilitates the connection between endpoint devices and desktops. This is by the way the default storage repository type. Azure; Dynamics; M365 Build a new skill set around Citrix XenServer 7. I have a 14TB Local SR so the 2TB Max file-system limitation of EXT3 is frustrating, since I use hardware raid. In thin storage, as the user consumes their allocated storage space, they are allocated more. StorageLink provides transparent access to all the thin provisioning and fast clone capabilities of the device. This is enabled by use of GFS2. Note: If you need to change the memory or vCPU hardware settings, use only the values documented in Licensing for the ASAv. In short, if you choose to deploy VDI on ScaleIO using XenServer, you will have to use thick clones for all VMs. NOTE: Although image files on Datto appliances are dynamic, sparse or thin-provisioned, when a VHD image file is copied from the device by using copy-paste or tools that do not accommodate dynamic/sparse/thin provisioning, the VHD image file will be copied with thick provisioning. Thin provisioning is called "sparse volumes" in some contexts. The storage server itself, however, can support thin-provisioning. lvhd-enable-thin-provisioning reqd params : sr-uuid, initial-allocation, allocation-quantum XenServer allows us to use two different types of thin provisioned SR’s ext3 and LVHD. You should always make sure your storage volume, aggregate, raid group, pool or whatever is capable of holding the data, or - if using thin provisioning - that a well tested monitoring system is available to alert you when running low on storage disk space. Do not install any supplemental packs. Thin provisioning and data deduplication were defined as requirements for the storage repository and must be enabled using XenCenter. Purpose of high availability Thin Provisioning (vSphere) / Provisioning Services (XenServer) Although these features are not fully comparable with each other (Thin Provisioning is using the same files for multiple VMs, where Provisioning Services is streaming a virtual operating system to a VM) the result is the same: saving disk space on the expensive storage. Many people are wondering where the Printer Management node used for replicating print drivers is located in Citrix XenApp 6. stringenable_thin_provisioning(session ref, host ref, SR ref, int, int) Upgrades an LVHD SR to enable thin-provisioning. First, you have to enable IntelliCache when installing XenServer, choosing Enable thin provisioning (Optimized storage for XenDesktop). Installed respectively on each ProLiant is Xenserver 6. Creating a VM or a VDI on an iSL NetApp storage array may consume more than 140% of additional space on the storage array. This includes the case where you are upgrading from an older version of XenServer. > Select default Local Storage to install XenServer and Enable thin provisioning option to optimized space. A Xen host runs a number of virtual machines, VMs, or domains (the terms are synonymous on Xen). You can also create local storage as ext3. As a result, images exported to Citrix Hypervisor (XenServer The only key management feature that is supported by both software programs is Thin Provisioning. Hello, I am running XenServer 6. 5 DVD. 본 글은 virtualbox에서 테스트 되었으며 XenServer를 따로 두고 윈도우 환경에서 XenCenter를 설치하여 관리 할수 있도록 작성 되었습니다. x focusing on the 7. citrix. Yes, I believe that that is correct. 14. The installation of Citrix XenServer can be automated through the use of an answer file, which provides the answers to the prompts during the installation. 2 버전부터 오픈소스화 되었습니다. 1. Here you have enable multipath for the Server. This should come as no surprise considering the benefits: reduced hardware costs, simplified management, and improved business continuity. Thin is virtual mode only. 6 service pack 2 or newer. It's a horrible scenario: Windows iSCSI target has no external cache awareness, it's SPOF so every time you have server down you'll have not only downtime but possible data loss. The next step occurs after the installation of XenDesktop itself where you create a connection to your host infrastructure. XenServer® answer file The installation of Citrix XenServer can be automated through the use of an answer file, which provides the answers to the prompts during the installation. In this guide, we will again extend on the excellent FOG foundation and add a menu entry to install an automated Citrix-Xen server. The SR and VDI abstractions allow advanced storage features such as Thin Provisioning, VDI snapshots, and fast cloning to be exposed on storage targets that support them. LUNs are allocated on demand using StorageLink and mapped dynamically to the host while a VM is active. 1 These tasks roll up into automated sequences managed from the XenCenter console and Enabling IntelliCache during installation is easy, just put a checkmark when asked “Enable thin provisioning”. tags: Citrix Provisioning Services Citrix Related Citrix XenServer Dell Wyse Thin Clients Microsoft Windows 7 Microsoft Windows Desktops Network File System (NFS) Server Virtualization Categories 2 – Installing Xenserver 6. 6 service pack 2 or newer. 3 Target Time Zone Changes: the target devices request the time zone information from the Citrix Provisioning Server at boot time and set the time zone to the connected Citrix Provisioning server. Boot with XenServer 6. Let's start with XenServer. 5 quadruples the maximum pool size from 16 hosts to 64 hosts. If you are looking for a guide how to silent install a XenServer with the latest updates and NVIDIA vGPU driver you came to the right place. XenServer is linked to XenDesktop & Citrix Provisioning server allowing application streaming but also Desktop loads on demand. The installer will then create a Storage Repository which has thin provisioning enabled. When thin provisioning is utilized, data de-duping can also be switched on to reclaim common blocks between VM images, thereby conserving even more space. Certified for VMware ® vSphere ™, Microsoft ® Hyper-V ®, Citrix ® XenServer ™, and OpenStack Cinder, Synology systems can integrate with your virtualization platform of choice and easily replace the aging SAN storage arrays in an organization's existing infrastructure. The thin pool can be expanded dynamically when needed for cost-effective allocation of storage space. Thin provisioning is implemented by using GFS2. Therefore, it is essential to make the appropriate calculation before you decide on the maximum disk space you want to allocate. Advanced management functions such as Thin Provisioning, iSCSI LUN Backup, MC/S (Multiple Connections per Session) and MPIO (Multiple Path I/O) are available on Synology NAS to strengthen the usability and stability of a network storage environment. Citrix XenServer 가 6. sincce we have the ISO file mounted to install XenServer let’s go for the “Local Media” option and continue. I am not selecting my 1TB SSD as I want that as a separate SR. • XenServer physical connectivity. 1. Using Thin Provisioning in LVM2 will allow for use to deploy volumes with more space than actually exists on the system. This website uses cookies and other tracking technology to analyse traffic, personalise ads and learn how we can improve the experience for our visitors and customers. Distributed Virtual Switch Controller (DVSC): DVSC provides centralized management and visibility of the networking in XenServer. 6 on block-based storage (via iSCSI software initiator or Hardware HBA). 1 . Choose Ok. Citrix used to recommend using NFS exclusively to go with MCS, but that was more geared towards the inability of XenServer to thin provision disks based on block based storage then anything else. James, in Citrix XenDesktop Implementation, 2010 Install the Target Device Software – Step by Step. There is a section “ PXE installation ” in the official manual, but that requires setting up or reconfiguring a DHCP server and a TFTP server. Thin-provisioning can increase the efficiency with which the storage resources are utilized. 5 DVD. I tried some suggestions like CTX120865, but this is not working on Xenserver 7. storage for XenServer® environ-ments, including XenDesktop® deployments, directly from XenCenter®. Thin provisioning, also known as virtual provisioning or thin storage, is a method of on-demand storage allocation based on user requirements in storage area networks (SAN), centralized storage disks, and storage virtualization systems. It maximizes the storage usage efficiency and eliminates the time of administrative tasks. 1, which began shipping today. Hopefully Citrix will support Inteliicache and thin provisioning in a future release of XenServer. Thin provisioning allows IT administrators to grow disk capacity in a linear fashion in response to actual use, instead of stochastically, in a costly step-function based upon forecasted capacity needs at some point in the future. Just as Citrix XenServer allows customers to gain greater leverage from server investments, the AssuredUVS thin provisioning management feature allows IT managers to provision more precisely as Citrix XenServer uses outdated EXT3 for Thin Provisioned local SRs. To illustrate further, Type 1 hypervisors run cloud-hosted environments, If you want to use Thin Provisioning to optimize the utilization of available storage, select Enable thin provisioning. In order to copy the hard disk of your virtual machine to the provisioning server vDisk, the provisioning server Target Device client must be installed on the virtual desktop. Rather than creating a fixed file size (fat provisioning), a small file grows on demand until it reaches a predetermined maximum size. Initiate a restart of the host server. In detail it does the following steps: 1. - Thin Provisioning: Allocate and consume physical storage capacity as needed in disk pools. File based and block based storage e). VHD files. We have previously set up PXE installs of XenServer, now we add in the XML answer file. x See full list on nakivo. Without thin provisioning, 370 GB of expensive hard drive space would be lost. I am unable to provision instances including systemvm-templates on xenserver SR's that are configured with the thin attribute specified. Future VDIs created in this SR will be thinly-provisioned, although existing VDIs will be left alone. Thin Provisioning and Reclamation: One of the toughest challenges of storage management is to decide how much storage space is needed for a computer or application. 02 by using PXE with answer files. Press F2 as quickly as possible. This blog will include those command lines and the PowerShell commands. Power on your Xenserver 6. First, you need to be on XenServer 5. x. Do not use the VMware-recommended memory configuration minimum, default, and maximum values. sh • Copy first-boot-script. /dev/sda2: XenServer uses this partition for temporary space during upgrades /dev/sda3: your storage repository should be in this logical volume We need to replicate the same partition structure across each of your drives and the software RAID volume will span the across the third partition on each disk. Thick and Thin Provisioning. Enabling IntelliCache involves configuration on the XenServer side and on the XenDesktop side. XenServer storage architecture B. One of these is in charge of running the rest of the system, and is known as domain 0, or dom0. Also, smbclient is a good tool to test SMB connects from a Thin provisioning allows you to allocate future disk storage space for a virtual disk without demanding storage space immediately. 1 . Network interface bonds D. Simply configure a cluster without shared storage. So for a 4 way, quad core system you can run XEN with Provisioning Server for all the VM's you can host on 16 cores and three other hardware systems for a total of $ 5,000 !!!! CTX200188 Citrix Provisioning Services 6. I recommend PVS for non-persistent desktops and NetApp clone for persistent desktops. A very nice feature of XenServer is the Resource Pool. XenServer physical connectivity ; Module 7: Storage. Storage locations d). 0 or greater. Let's start with XenServer. XenServer networking architecture b). The following is a list of changes in this version: 1) [Feature] The Storage System in Virtualizor has been revamped. Key features • High availability a). If I recall correctly, and I may not, thin provisioning is a bit different in XenServer. 1. Set a good *XENSERVER_ROOT* password. • VHD files. Figure 6: Make decisions for how you want to manage storage. xml While thin provisioning allows you to use disk space more efficiently, you also risk running out of physical disk space if the VMs need more space than anticipated. In your very first post, you asked how to enable it for Xendesktop, without reloading. MCS combined with Hyper-V local storage is also optional. First, you need to be on XenServer 5. Skip verification of the installation media. Enabling IntelliCache involves configuration on the XenServer side and on the XenDesktop side. Storage multipathing f). openstack. The ext3 type SR is around much longer and as the name implies it is a simple EXT3 linux volume. 1 Long Term Services Release, which delivers optimized server virtualization for all datacenter workloads. -SSD Read Cache: Increase execution speed of applications by caching previously read data - IP & FC Remote Replication: Safely replicate data to any global location that includes mirroring thin provisioned pools Citrix Provisioning; Receiver; ShareFile; Citrix Virtual Apps (XenApp) Citrix Virtual Desktops (XenDesktop) Workspace; Workspace app; Microsoft. The idea behind thin provisioning is to create a pool of virtual storage that is allocated to users in the conventional fashion. The Integrated StorageLink software, which allowed XenServer to access the snapshotting, replication, and thin provisioning features of storage arrays, is deprecated, as is the Distributed Virtual Switch Controller and the hooks into Microsoft's Systems Center Virtual Machine Manager. Module 3: Installing XenServer Understanding thick and thin provisioning Network QoS line Storage locations Disk prioritization Hardware requirements File based and block based storage XenServer vGPU and GPU pass-through Boot with XenServer 6. When XenServer is installed with Intellicache, you have to re-add the XenServer host in XenDesktop and enable Intellicache. Provisioning Server does not leverage IntelliCache technology today. The Virtual SAN Appliance evaluation software makes it easy to try Citrix Essentials with a StorageLink-certified, iSCSI shared storage SAN that can pool up to 1 Terabyte of disk space, efficiently “Thin Provision” storage to virtual machines, speed up application performance, and create snapshots for Instant Volume Cloning and Fast Disk-to-Disk Backups. The performance of a thin-provisioned disk is not higher than that of a lazy zeroed thick-provisioned disk, because for both of these disk types, zeroes have to be written before writing data to a new block. However, No thin provisioning on XenServer with block based storage. The only way to get thin provisioning within XenServer & XenDesktop is by using shared storage presented as NFS or volumes presented as EXT3, which in this mix of ingredients, applies to local disk only. Solution: A Xen host runs a number of virtual machines, VMs, or domains (the terms are synonymous on Xen). Module 7: Storage • XenServer storage architecture • Understanding thick and thin provisioning • Storage locations • File based and block based storage • Storage multipathing • XenServer Intellicache • XenServer in-memory read caching • XenApp and XenDesktop Provisioning enhancements. XenServer 7. If you allocate too little you may run out of space, too much and you waste valuable storage resources by tying it up to one computer. On-demand allocation of blocks of data versus the traditional method of allocating all the blocks up front makes storage space consumption only happens when the data is accessible from XenServer administrative interfaces. volumes. The PXE boot file could look like: default local prompt 1 timeout 60 label local localboot 0 label install-xenserver […] If your XenServer hosts are configured with static IP addresses, be sure that the switch ports connected to the XenServer hosts are configured as detailed in Citrix Knowledge Base article CTX123158 before attempting an upgrade. Thin Provisioning allows the administrator to present more storage space to the VMs connecting to the Storage Repository (SR) than is actually available on the SR. sh • Copy first-boot-script. During installation of XenServer, select "Enable thin provisioning (Optimized storage for XenDesktop)"; see Fig. 1U1 installed in VM; During Xenserver setup: Enabled thin provisioning (Optimized storage for Xendesktop) Storage size after install: After installation I expanded the virtual disk of this VM (where Xenserver is running in) with 20GB. xe sr-create host-uuid=ba3d140c-3de5-499b-b831-7c40d82958a9 content-type=user type=lvm device-config:device=/dev/sdb shared=false name-label="Local storage 2" Second option: Create a LVHD storage repository with thin provisioning support.
