Hi Francesco,

no problem, life keeps one busy :)

I am still facing problems with kvmgt and a Windows 10 vm but I am not quite
sure if this is still the same issue.

In the meantime I first updated to kernel 5.2 and faced following issue:
https://bugs.freedesktop.org/show_bug.cgi?id=111582

Then I updated to kernel gvt-staging (5.4.0-rc4-17331-g9074777-dirty) from
https://github.com/intel/gvt-linux which works much better and crashes not that
often but still does. Unfortunately the qemu process gets zombified when the vm
crashes and I have to reboot the host (and all other VMs) to get the Windows vm
running again :\

I cannot reproduce when or why the crashes occur. I tried to update Intel GPU
drivers in the vm but everything newer than version 26.20.100.6709 from 11th of
April 2019 leads to a non working passed-through gpu in Windows as it cannot be
started.

I will attach messages from the last crash that happened while the Windows 10
VM was idle with some programs open which had been started hours/days before
and ran without problems. 

Best regards
Alex
