The host is Ubuntu 10.10 x64 The drivers are from http://alt.fedoraproject.org/pub/alt/virtio-win/latest/images/ 1.1.11-0 released on 17-Aug-2010 - are there any newer drivers? > > What's the windows virtio driver version?

I had a crash today but no logentry on the host - but that could be because I had to restart syslog (ran out of diskspace after turning on debug logging ob libvirtd - didn't think that it would generate 6 GB of logs per day :-) > > > > Sounds like an interrupt storm to me.

I prepared this. When the system crashed today I didn't have the complete memory dump ready - so I only have a minidump. The intersting point is that the system today crashed with a BSOD and didn't freeze.
