bishyb Posted April 25, 2016 Share Posted April 25, 2016 Hi all, Just thought I'd post this to check if anyone has seen this behaviour or knows how to fix this one. Have a Windows 10 VM setup and everything running well, until I restart the VM and the VGA output from the passthrough graphics cards (Nvidia GT 430) doesn't return/work after the VM has restarted. If I turn off VGA passthrough and restart the VM instead of a VNC session it restarts fine. The only way to recover the VM is the fully restart the host machine running unRAID, and then the VM boots fine after that. Settings: - unRAID: 6.2 Beta 21. (Behaviour the same in 6.1.9 also) - BIOS: SeaBIOS. (OVMF doesn't work with this graphics card) - Hyper-V: No. - VirtIO v0.1.109 (Tried 112 and 117, no difference). Any advice welcome Thanks, Andrew.

testdasi Posted April 25, 2016 Share Posted April 25, 2016 I think I read somewhere about unRAID not liking passing through Nvidia GPU placed on primary slot. Other than that, I bet someone will ask you to attach diagnostic log. Quote Link to comment
saarg Posted April 25, 2016 Share Posted April 25, 2016 Your GPU most likely doesn't support to be reset. What you can do to avoid restarting unraid is to safely remove the GPU before you reboot the VM. It's done the same way as with a USB stick. Quote Link to comment

SpaceInvaderOne Posted April 30, 2016 Share Posted April 30, 2016 another thing you can try is to specify the rom file. http://lime-technology.com/wiki/index.php/UnRAID_6/VM_Management#Edit_XML_for_VM_to_supply_GPU_ROM_manually, but i think it is as saarg says the card doesnt reset.

Is this because Windows 7 is using Seabios? while Openelec uses OVFM i think OVFM does something that helps with this problem. Quote Link to comment
