Public bug reported:
Until I upgraded to raring, freebsd guest has been one of my most stable
guest under kvm (and previously under vbox for that matter).
Since the upgrade to raring, my existing guest hangs very early in the
boot process ending with the following in
/var/log/libvirt/qemu/freebsd8.log :

qemu: terminating on signal 15 from pid 2474
2013-03-20 07:49:36.834+: shutting down
To isolate the issue (and hoping for some change in more recent freebsd
versions) I tried creating a new vm but hit the same issue.
Using ftp://ftp.freebsd.org/pub/FreeBSD/releases/amd64/amd64/ISO-
IMAGES/9.1/FreeBSD-9.1-RELEASE-amd64-bootonly.iso , I end up with the
following /var/log/libvirt/qemu/freebsd9.log which includes the kvm
command :
