I updated last week my lab at home : XenServer 6.0 to XenServer 6.0.2 Provisioning Services 6.0 to Provisioning Services 6.1 and XenDesktop 5.5 to XenDesktop 5.6 Everything went well for XenDesktop, update was smooth and VDA update was successful and simple as well. I did the setup of Personal vDisk successfully and it worked without doing anything specific. Then I wanted to built a new Windows 7 golden image to take a fresh start and install the less application possible, this is when I began to have an issue with Personal vDisk : Startup failed Personal vDisk failed to start because the snapshot inventory has not been updated. Update the inventory then try again. Status code: 15 Error code: 0x0 Alright, I had a freshWindows 7 VM updated to the last Microsoft patches with Acrobat Reader installed, PVS Target Device, Citrix Profile Management, EdgeSight and XenTools... Every time I was creating a new vDisk using Imaging Wizard, the operation was successful but all the VMs I tried to launch after had this issue... I got the log files to try to understand what was wrong by clicking on the collect logs button : I got a zip file containing PvDSvc.log.txt, PvDWMI.log.txt and SysVol-lvmSupervisor.log, I will just past an excerpt here : Clearly with the SysVol-lvmSupervisor.log file, something was wrong... It took me some time to figure out what could be wrong. I just noticed every time I wanted to use Imaging Wizard, when the VM needed to reboot to load the vDisk and boot, before restarting the Personal vDisk inventory manager was launch and requested to be updated... So I did the update but at every reboot the same pop-up came again and again... I went to read the "manual" : To update master images that use personal vDisks You enable the personal vDisk feature for use with a master image when you install the Virtual Desktop Agent. During the installation procedure and after any update to the image after installation, it is important that the disk's inventory is refreshed and a new snapshot is created. This procedure describes the required steps. Because administrators, not users, manage master images, if you install an application that places binary files in the administrator's user profile, the application is not available to users of shared virtual desktops (including those based on pooled catalogs and pooled with personal vDisk catalogs). Users must install…
