[Spice-devel] Blank screen on SPICE when using vGPU

[James Freeman]

Hi all,

Conscious this might not be a SPICE issue but trying to debug where the 
issue is right now. I'm working with someone who is using RHV 4.2 with a 
vGPU configuration. At present we are stuck on a problem whereby the 
vGPU can be successfully assigned to a given VM (either Windows or 
Linux) and then the VM booted. However as soon as the closed source 
nVidia drivers are installed and the VM rebooted, the SPICE display is 
blank (all black).

Trying to determine where the issue is - with the Windows VM we have 
been able to RDP in and see that the nVidia driver was loaded and the 
nVidia control panel loads - this would seem to indicate the driver is 
loaded and working. Still running some additional tests on the Linux VM 
- however we're trying to figure out where the problem lies. Is it 
possible this is an interaction with SPICE, or is this likely an issue 
at a lower level? Is there a suggested route to debug this issue?

Kind regards,

James
