saying that guest SMP isn't working for you? The host OS definitely shouldn't crash. Can you be more specific about what configs you are using? There was a host oops fixed in kvm-36 so upgrading may help you.
exactly. i've got 4 phisical core (Intel Core 2 Quad) and i try to give 4 cpus for 2 guests and 2 cpus for a third guest and restart libvirtd. the result was that even the host system crash without any stack trace or kernel panic and only the hard reset helps.
Could you try to reproduce the problem with kvm-36? Host crash bugs are very important to fix especially one so easily reproducible.
yes, when c5-testing will include kvm-36. i already recompile many rpms to be able to use the latest tools, but since kvm is in centos-extras i'd rather stay with that and don't mix packages.
