I use Win 8.1 guest and passed through an Intel HD 520, installed
successfully latest driver 126.96.36.19948, but I can't enable the graphics
card in the display settings. In Win 8.1 setup is default as an extended
display, but no matter how I change the settings (change primary display,
"show desktop only on Intel HD520", the card doesn't start working. In
device manager all looks normal.
Even if I disable the Redhat QXL graphics card in the device manager, the
monitor just turns black.
Tried with VNC and SPICE. Tried virt-manager, spicy, remote-viewer. No
Further, when the vgpu is passed through, I start to have mouse issues.
Mostly no mouse is visible, sometimes mouse is only invisible but useable.
Tried passthrough an extra mouse, no effect.
What is best practice? How you use the Windows machine with the vgpu?
Help is very much appreciated!
