freebsd 6.2 i486 does not boot under kvm

[Aurelien Jarno <aurelien-rXXEIb44qovR7s880joybQ@public.gmane.org>]

Hi all,

Today I have just tried kvm, as it seems to be a really good replacement
to qemu, as it is a lot faster. I don't really have confidence on kqemu,
so I don't use it. I am using it on my laptop to be able to develop
while I am away from my various computers.

I am really interesting in having FreeBSD working under kvm (actually
GNU/kFreeBSD, but that's almost the same kernel), so I have tried to
boot FreeBSD 6.2 for both amd64 and i386 versions.

I haven't used it a lot, but the amd64 version seems to works very well.
Great work!

About the i386 version, I get a kernel trap (see below for the log).
Does anybody have any idea of the problem?

I am using kvm 12 on an amd64 machine. I have got the same problem with
both kvm modules from kvm 12 and from kernel 2.6.20-rc6-git1.

Thanks,
Aurelien
