Hi,
I'm currently tryin to find out why I'm running into nidia gtx 1050 ti -
windows 10 - driver installation issues.
I've found out that the machine still shows that it is running in
virtual guest:
root@debian:~# cpuid | grep -i hypervisor
hypervisor guest status = true
hypervisor_id = "@ @ "
Setting of vendorid seem to work. It was something with "KVMKVM..." before.
I have not clue why this happens...
Maybe someone has seen such behaviour before.
I'm currently using:
debian 9
4.9.0-2-amd64
qemu 2.8+dfsg-4+b2
Passthrough works in geral but only has the windows driver issue. I
guess that the "hypervisor guest status" value is the flag which is the
cause for it.
Command line looks like this (I started a linux machine inside to get
the cpuid output):

Thanks in advance... Maybe it is something for the qemu mailing list...?
