I´ve now tested to create a new FreeBSD server with dual cores in our experiment/test system and it worked, no problemo.

so seems like you have different: kernel seabios libvirt
can you please upgrade them one by one to find the culprit (I'd do in this order for simplicity of rollback: seabios, libvirt, kernel)
Done. Kernel is the culprit!
We have two hosts in the test system, so what I did was to first update seabios; test, then update libvirt; test, kernel; test on host1, where all was well until after booting new kernel. So I wanted to know for sure that it was only the kernel's blame, so on host2 only kernel was updated and afterwards the issue started appearing. So definitely, kernel.
PS. As I expected, downgrading the packages again failed horribly. I friggin' hate trying to downgrade, even for just a few packages, I opt-out and rather just reinstall the whole thing to save me the headache:)
please open a bug on fedora kernel, and paste here. thanks well, i guess next question is does fedora 18 kernel solves the issue...
thanks. dor/karen - is there anyone who can take a look at this fedora regression causing SMP vm's to panic with a kernel upgrade?
Thanks for the report, I assigned it to Marcelo (CCed)
thanks, Itamar
