Description of problem:
Very often when I shut down a guest, the libvirt connection closes and I get an error message:

Error polling connection 'qemu:///system': Unable to read from monitor: Connection reset by peer

Error polling connection 'qemu:///system': Unable to read from monitor: Connection reset by peer

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/engine.py", line 440, in _tick
    conn.tick()
  File "/usr/share/virt-manager/virtManager/connection.py", line 1507, in tick
    vm.tick(now)
  File "/usr/share/virt-manager/virtManager/domain.py", line 1531, in tick
    info = self._backend.info()
  File "/usr/lib64/python2.7/site-packages/libvirt.py", line 1411, in info
    if ret is None: raise libvirtError ('virDomainGetInfo() failed', dom=self)
libvirtError: Unable to read from monitor: Connection reset by peer


The main virt-manager window now says:

localhost (QEMU) - Not Connected


Closing the error message window and double-clicking on the localhost line prompts me for the admin password again, and re-establishes the connection.

Version-Release number of selected component (if applicable):
virt-manager-0.9.0-7.fc16.noarch
libvirt-0.9.6-2.fc16.x86_64
qemu-kvm-0.15.1-3.fc16.x86_64

How reproducible:
Often.
