[libvirt] Why does vnc show blackscreen after using mstsc to connect to a windows vm with a nvidia gpu passtrough

[Wu Zongyong]

Hi,

As the title says, VNC inside a windows virtual machine doesn’t work after I try to use mstsc to access the vm with a gpu passthrough.
It seems that the scenario is normal, but could someone tell me something deeply about the reason why vnc shows blackscreen? 

Thanks.
