Re: [ovirt-users] Nvidia Tesla M60 Direct GPU-Passthrough giving issues + VNC

Hi, I am running an Ovirt host on a SuperMicro SuperServer 2028GR-TRH equipped with 2x2 Tesla M60s (they are dual GPU Cards). I've followed this guide- https://www.ovirt.org/develop/release-management/features/virt/hostdev-pa... and managed to get a Windows 10 Enterprise guest running with one GPU attached to it. The windows guest successfully detects the single M60 GPU and I can install the latest Tesla drivers (390.65) on it with no problem. However, the GPU refuses to do any work whatsoever. The control panel says the GPU is being used for compute and not as a VGA adapter (shows up as inactive on the activity monitor). Nvidia's GPUModeSwitcher tool tells me that the GPU is in Graphics mode, so there is a driver issue here. I have access to the GRID Drivers. However I'm not sure why I'd need them as I'm only doing a direct-passthrough, not GPU Virtualization. Any ideas?

Also, after activating Device-Passthrough, I'm unable to access my VM's via the Hosts' VNC anymore. I get an "unable to connect" error. Im currently accessing the Guests with a direct VNC connection. Problem is, I can't clone/create new VMs anymore because of this. I must've done something wrong, not sure what.

Thanks in advance! -- Yours Faithfully Ravyu
