• PvD intercepts application I/O requests (files, registry keys, registry values) and redirects these requests.• Requests are satisfied from the base Virtual Machine or Personal vDisk.
• PvD decides which layer to satisfy the request from by consulting a set of rules called the resource catalog.
• PvD provides a blended view of both base Virtual Machine and the users Personal vDisk.
What Does Personal vDisk Do?

Personal vDisk• This part is seen by the user as Drive P:\
• Used for USERDATA e.g. My Documents
• By default user is allowed 50% of the PVDisk
• This part is Drive V:\• It’s hidden from the user• Merged with the Diff Disk• Seen by user as Drive C:\• E.g. Installed apps
• PVDisk is created by copying UserData.VDESK.TEMPLATE from Base VM during catalog creation
• 10GB by default with 50/50 split for User Data / App Data
Operating System
•Common Base Setup •Install OS, common apps and VDA in base VM
•Create VM pool and entitle
•User Access•Login through XenDesktop Client
•PvD assigned on first login•Locally administered/User installed/streamed apps
•Image Update•Update base VM without affecting any user personalization

Citrix Confidential - Do Not Distribute
• Upgrade options exist for • XenDesktop 5, XenDesktop 5.5 and the VDA
• A ‘mixed’ site is permitted• Controllers running XenDesktop 4, 5 and 5.5 can control desktops running
XenDesktop 5.6 VDA’s.• Controllers running XenDesktop 5.6 can control desktops running the only the
XenDesktop 5.6 VDA.• Desktop Studio from XenDesktop 5 SP1 can manage sites created with
XenDesktop 5.6 unless they include desktops with PvD.• Desktop Studio from XenDesktop 5.6 can manage sites created with
XenDesktop 5, 5 SP1.
How do I install PvD?
• After installation/upgrade you need to configure a Site• This includes, Licensing, Database set up and Host connection
• Desktop Deployment Wizard is used to configure a site• Quick Deploy Wizard cannot be used with PvD
Controller Installation / Upgrade
Add Personal vDisks to existing hosts
• In Desktop Studio• Select host• Select Enable Personal vDisk• Add Personal vDisk storage
XenDesktop 5.6 – Post Installation (Existing Hosts)
Add Personal vDisks to a new site
• In Desktop Studio• Create a catalog
• Pooled with Personal vDisk (MCS)• Streamed with Personal vDisk (PVS)
• Number of VMs • Size (min of 3GB)• Drive letter
XenDesktop 5.6 – Post Installation (New Hosts)
• VDA can be installed in two modes: • Virtual Desktop Agent – includes the new features of XD 5.6• Virtual Desktop Agent for HDX 3D Pro
• Enable Personal vDisk for VDA• PvD is always installed. You either enable
or disable the drivers.
Virtual Desktop Agent Installation
PvD Disk
• May be attached to any storage targets defined in the hypervisor• Thin provisioning is supported for those hypervisors that support it• Can be located on same VM, or different (IOPS split among locations)
• Default size and location selected in Desktop Studio catalog creation• (or PVS XenDesktop Setup Wizard, if PVS in use)
• PvD disks can be resized
• The PvD inventory consists of a few things …• The resource catalog• A set of 0-byte files which track files sourced from the base VM• Essentially information about what is installed in the base VM
• The inventory is created by the administrator• Start -> Citrix -> Personal vDisk -> Update Inventory• At each base VM shutdown via the shutdown tracker• These options are only available in the base VM
What is a PvD Inventory?
25
• The inventory is computed and placed in the template VHD• i.e. the resource catalog and sentry files corresponding to the base VM
• The template VHD is saved for use during first time boot in Pooled VM mode
• After inventory creation a snapshot is taken and the XenDesktop catalog is created• An empty, unformatted volume is attached to each virtual machine• This volume becomes the Personal vDisk for the user of that VM• Initial size and SR location are obtained from DS/PVS setup wizard
Template VHD
26
• MCS / PVS starts each VM in the pool
• The Personal vDisk driver detects the unformatted volume and formats it
• The template VHD from the base VM is copied into the new volume.
• This is a VHD inside a volume
Pooled VM – First Time Boot
27
• On each subsequent VM boots the drivers perform the following tasks …• Detects the volume with the VHD inside• Mounts the VHD• Load the resource catalog from the VHD into the system registry• Begin interception / virtualization
• PvD also will detect if the volume has been increased in size and resize the VHD if needed
Pooled VM – Subsequent Boots
28
• Over time users will make changes to their environment• Add/delete/change files• Add/delete/change registry keys/values• Install/uninstall software (if rights permit)• Receive provisioned applications (eg, via SCCM)
• It’s important to note that PvD captures all changes being made• These changes are redirected to the PvD VHD file• No changes to the VM image are permitted
Pooled VM – User Changes
29
• Base VM images can and will change over time
• A new inventory will be computed and stored in the base VM
• On next pooled VM boot the VM will notice that it is out-of-date with respect to the new base VM• PvD drivers will mount the VHD and merge the changes from the previous
inventory with the new inventory, respecting any changes made by the user.• After this 3-way merge the VM will restart.
• Note – the broker will stop user logins during image update
Base VM – Life Cycle
30
• PvD is not a User Environment Management solution
• Be aware of the 50/50% profile and apps split
• PvD turns pooled VDI into pooled-static
• Admin always wins
