[vfio-users] Troubleshooting UPT Mode

[Jonas Shoor]

Hello,

I was wondering if anyone could help me troubleshoot getting UPT mode
working for my Windows 10 guest.  I was able to get Legacy Passthrough mode
to work; however, when I try UPT mode, I receive the message "Guest has not
initialized the display (yet)." in VNC and my external monitor is blank.
My understanding is that with UPT, VNC should be my primary display and i
should be able to configure my external display as a secondary which will
mirror my primary. However, since my primary is not initializing, I am
stuck.

I am running a proxmox 5 server with the following configuration:
kernel: 4.10.17-2-pve
Qemu: pve-qemu-kvm_2.9.1-1
Seabios
CPU: i3-7100 Kaby Lake
KVM/QEMU command:

/usr/bin/kvm -id 102 -chardev

-rtc 'driftfix=slew,base=localtime' -global
'kvm-pit.lost_tick_policy=discard'

I didn't see any obvious errors in my log files.

I'd be happy to post the working Legacy configuration if that would help.

Thanks in advance,

Ed
