Hello,
When i try to run FreeBSD-amd64 on more than 1 vcpu in quemu-kvm
(Fedora Core 17) eg. to run FreeBSD-9.0-RELEASE-amd64 with:
qemu-kvm -m 1024m -cpu host -smp 2 -cdrom
/storage/iso/FreeBSD-9.0-RELEASE-amd64-dvd1.iso
it freezes KVM with:
KVM internal error. Suberror: 1

Artur,
Can you check whether
https://patchwork-mail.kernel.org/patch/1942681/
fixes your problem
Hi, thanks for the reply.
Unfortunately, the patch does not help. Attempt to start FreeBSD
amd64 via quemu-kvm with -smp parameter greater than 1 fails in
exactly the same way as before.
The patch was applied to the kernel from the 3.6.11-1.fc17.src.rpm package.
Do I need some additional patches?
Can you try queue branch from kvm.git?
Thanks for the advice - I used kernel from kvm.git(queue) and was able
to run FreeBSD-amd guest with SMP on my kvm-host server without previous
problems. Unfortunately, after few hours server was hung up. Case
requires further investigations, but generally speaking we went forward.
Unfortunately, experiments on the server are difficult, because it is
used for everyday work.
