I posted this on another, older thread on the GRID forums so I am posting a fresh topic here too.
I have XenDesktop 7.1 running on a number of XenServers with K1 and K2 cards.
The virtual desktops are bluescreening at random times and referencing the driver, dxgmms1.sys. I understand that this is a DirectX driver. Most of the time, I actually find the virtual desktops started in Windows Recovery Mode. I have been able to catch it bluescreened though. Windows event logs do not show anything leading up to the issue. I believe these machines are just bluescreening while idle as no users have reported getting kicked out during a session.
The virtual desktops are bluescreening across various different hosts and GPU profiles. The are bluescreens on both K1 and K2 passthroughs and vGPU profiles K120Q and K140Q.
All the virtual desktops are 64 bit Windows 7 and there are no Direct X updates showing as needed from Windows Update.
If I run DXdiag, it shows that I have DirectX 11. Microsoft notes that this tool reads "DirectX 11" even if the systems have DirectX 11.1 or 11.2. I also ran the 64bit DxDiag and it said that there were no problems found.
I updated XenServer and the GRID Manager a couple of weeks ago but the issue occurred before then. Here are my current drivers below. If you go to this site http://www.nvidia.com/download/driverResults.aspx/77752/en-us as of 9/22/2014, I am using all the latest drivers from release "331.59.01/332.83"
From Windows Device Manager: 184.108.40.20683
All XenServers have: NVIDIA-vgx-xenserver-6.2-331.59.01.i386.rpm
Build Date 2014-06-26
BUild Number: 70446c
Has anyone else experienced this or have any ideas on next steps?
Thanks for your help!!
