The last time I checked, FreeBSD/DomU was highly buggy, and this
includes SMP support.
I never managed to get around to figuring out what wasn't being locked

Dear all,
When I try to make FreeBSD work in Xen domU with multiple vcups, I got a
kernel panic. If someone have a clue .
I got the following error :
