Ubuntu - GPU - GPU pass-through - Configuring the guest

Use Virtual Machine Manager or virt-install to install the guest VM.

Install the graphic card driver

Depending on the GPU follow the specific steps for that GPU.

See: TODO.

NOTE: Display issues.

After you have installed the drivers, the Virtual Machine Manager display will lose its connection to the guest OS.
To access the guest VM, either login via ssh, change to the console interface, or install a dedicated VNC server in the guest.

To avoid a flickering screen, stop and disable the display manager:

sudo systemctl stop display-manager && systemctl disable display-manager

TODO

Hide the hypervisor from the drivers by using the <hidden state='on'/> directive in the guest's libvirt definition, for example:

<features>
 <acpi/>
 <apic/>
 <kvm>
  <hidden state='on'/>
 </kvm>
</features>
