Title:
  kvm hangs for freebsd guests since raring upgrade

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  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+0000: 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 :

  From that,

    KVM internal error. Suberror: 1
