Hi!
OpenBSD 5.0/i386 throws a kernel panic when I try to
boot it inside a Linux KVM (host: vanilla 3.0.4,
openSUSE 11.4/x86_64) unter qemu-kvm 0.14.1 and 0.15.1.
Note that OpenBSD 4.9/i386 works.
The OpenBSD developers say:
"the virtual machine emulator you are using has a bug. it declares
a cpu type from upstream and then does not emulate certain functions
of that cpu."
Therefore I'm reporting this here.
More from m...@openbsd.org:

k1x_init() is not related to vmt, it is from k1x-pstate.c, which
is cpu power state driver for K10 processors.
Thread on m...@openbsd.org with full OpenBSD dmesg:

Since both qemu-kvm 0.14.1 and 0.15.1 show identical
symptoms, I assume this is in deed a KVM kernel bug.
Can somebody reproduce this?
Please CC: me when replying, thanks.
I'll follow the kvm@vger archives, though.
Regards,
Walter
