libvirt users - Oct 2014 - Re: VGA as vfio-pci and vnc server's blank/black display

hi,

I'm having a Radeon as vfio-pci, which seems to work 
perfectly fine, but...
Qemu's model type='vga' gets "exlaimed" in win2k8's
Device
Manager with:
"
Windows has stopped this device because it has reported 
problems. (Code 43)
"

Now, that does not bother me that much as all I need on 
regular basis is RDP but VNC connection gets me nowhere.
I get blank/black screen, it connects without 
errors/problems but nothing more.

I know you would say VGA passthrough is only supported for 
very few VGA adapters but is the situation I describe 
normal/expected?

regards

in case I wasn't clear I'll only add that that "Standard 
VGA" in guest gets exclaimed ONLY when that second VGA is 
passed through.
Otherwise it works and VNC display works too.

not working. (haven't tried connect to spice yet)
