I’m currently having different issues with XenDesktop setups on 7.11 & 7.12 that have Grid K2 (any profile) attached.
All the setups are on up-to-date hypervisors (XenServer 7 / vSphere 6) that are fully patched.
Nvidia GRID is also on the most recent version (release November 2016)
On Windows 7 the issues are that the sessions most of the times freeze during Windows Logon (the circle just stops spinning) when the user starts directly in a Dual Monitor Full screen mode.
Connecting in a Window or Single Full screen mode seems to be more stable (so I’ve created a reg key that deletes the registry keys where the last known connection mode is saved so sessions always start in a Window Mode).
On Windows 10 (fully patched, anniversary update included) the screen just stays black. Switching between Full or Window mode sometimes fixes the problem.
The Windows 10 VDI’s are only deployed with K240Q (or higher) profiles because of the known issues with profiles that have 512Mb or less memory.
I’ve tested the above issues with different policy settings: H264/ThinWire Plus - Visual quality - Disable NVENC (on the K240Q profiles) … but none of them make it more stable.
Also made sure the Windows Power Settings are set to Max. Performance (as noted in the Release notes a Black screen issue may appear) and applied the fixes mentioned by Citrix https://support.citrix.com/article/CTX135782 .
When the session does start performance and stability seams to be ok.
When the vGPU is removed all problems are fixed.
Downgrading to XD 7.9 seems to fix it for Windows 7 VDI’s (need to test it on Windows 10)
To be sure XenDesktop 7.11/7.12 works on Windows 10 I’ve tested it with an Intel GVT-g vGPU and not having issues there.
On XenApp 7.11/7.12 with a vGPU attached (and changed to necessary registry settings to allow Graphical performance on Windows Server) all seems to be ok.
Already created 2 cases with Citrix but both without any luck of figuring this out (after creating a ton of CDF/Memory Dumps/Network traces).
So I’m wondering if anyone else has similar issues with XD 7.11/7.12 and Grid K2 cards
