--- Comment #7 from François Gouget fgouget@codeweavers.com ---
From the todo list:
1) I created an init.d script so the workaround should now automatically be applied on boot. It might be simpler to use a modeprobe.conf file though: echo "options kvm ignore_msrs=1" >> /etc/modprobe.d/local-kvm.conf Neither has really been tested since the hosts have not been restarted yet.
4) On my machine (i7-4790K) I have: $ cat /sys/module/kvm/parameters/ignore_msrs N
Yet, I cannot crash the wtbw7u VM when I use its Windows 10 snapshot (that VM has been upgraded to Windows 10, though the TestBot only uses the Windows 7 snapshot for now).
But with the wtbw1064 VM the crash happens just as for the TestBot: - I get the same kvm errors in /var/log/syslog. - The same workaround fixes the issue.
This means this issue depends on some aspect of the guest environment and not just on the host's configuration or CPU.
5) The point above confirms that this issue does not happen on all Windows 10 guests.
7) I uploaded source code to reproduce this issue.
All that remains now is checking if this issue happens on AMD processors (3, but this seems optional), and reporting to QEMU (2) and recording the reference here (6).
