Description of problem:

libvirtd in F12 leaks pretty bad when you make invalid
requests against the daemon.  For example, try doing

  # virsh dominfo 0

in a loop on a machine running qemu/kvm hypervisor.

Dan tells me that this is fixed by the following upstream
commit:

Version-Release number of selected component (if applicable):

libvirt-0.7.1-10.fc12.x86_64

How reproducible:

Run this command as root several times, or in a loop:

  virsh dominfo 0
