Hello,
When i try to run FreeBSD-9.0-RELEASE-amd on more than 1 vcpu in
quemu-kvm (Fedora Core 17) eg. 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
emulation failure

This also applies to FreeBSD-7.3-RELEASE-amd64 and FreeBSD-9.1-RC3-amd64
(other releases not tested).
When quemu-kvm is started without SMP (1 vpcu) amd64 FreeBSD kernel
boots correctly. I did not notice this problem for the i386 versions
(FreeBSD-7.3-RELEASE-i386, FreeBSD-9.0-RELEASE-i386, FreeBSD-9.1-RC3-i386).
