Re: Xen 8 & 9 DomU kernel panic with 2 or more virtual CPU
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 correctly. :/ Adrian On 1 April 2010 00:49, Guillaume Seigneuret wrote: > Dear all, > > > > When I try to make FreeBSD work in Xen domU with multiple vcups, I got a > kernel panic.

Re: Xen 8 & 9 DomU kernel panic with 2 or more virtual CPU
This seems to affect most people trying to use FreeBSD on xen i386 paravirt. I was trying it on Linode, and got 8.0-RELEASE to actually boot by hacking MAXCPU to 1 in sys/i386/include/param.h but even then, when it was under load (building world or lots of ports) it would occasionally panic. 8-STABLE wouldn't even boot with MAXCPU hacked to 1 to avoid VCPUOP_initialise panic, throwing panic on HYPERVISOR_update_va_mapping instead. I played around a bit with hacking the sys source, but I don't know enough about XEN or even FreeBSD kernel behavior to figure out what's going wrong here.

I'll take a look this week.
