I have the following setup, which works fine in direct pass-through mode, i.e. 1-1 GPU to VDI, however if I select any of the K profiles (K280Q, K260Q etc.) then I can only power on a single VDI. When the next VDI is started then it fails to boot with the error "An emulator required to run this VM failed to start"

Haven't done much troubleshooting so far, just wanted to post something quickly in case anyone had a quick fix for this. Really annoying as all looked so promising with direct 1-1 pass through before I licenced XenServer and the new profiles became available (the additional profiles are a 'premium' feature requiring licencing).


HP Proliant WS460c Gen8 WS Blade
HP BIOS I31 06/01/2015 (Setup Mode/Max Performance Profile)
HP SW 460 Expansion Blade containing:
NVIDIA GK104GL GRID K2
Driver Version 361.45.09
XenServer 7.0
XenDesktop 7.9

Thanks,
Darren

Might be worth asking on the XenServer forums: http://discussions.citrix.com/topic/378788-vms-failing-to-power-on-with-xenserver-7-using-dell-per720-and-nvidia-k1/


Although that specific server and verison of XS not on the HCL, very similar combinations have been....

Might also be worth enquiring with XenServer HCL as it's possible there is a know issue that means it's not supported...

Thanks Rachel, I have done as you suggest and posted in the Citrix forums.
