<pre>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:
<a class="bz_bug_link
bz_status_NEW "
title="NEW - VGPU fails and kills KVM host"
href="show_bug.cgi?id=111582">https://bugs.freedesktop.org/show_bug.cgi?id=111582</a>
Then I updated to kernel gvt-staging (5.4.0-rc4-17331-g9074777-dirty) from
<a href="https://github.com/intel/gvt-linux">https://github.com/intel/gvt-linux</a> 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</pre>
