[Bug 706828] [NEW] Connection refused for monitor socket on kvm restart

[mixter]

Public bug reported:

Binary package hint: qemu-kvm

This issue exists with a recently installed 10.04 (lucid) system with
all packages fully updated as of today.

I installed a new Windows 7 guest on "localhost (QUEMU)" which was then running fine.
Once I attempted to restart the guest, I expected the guest to start up but got the followingerror popup:

"Error starting domain: monitor socket did not show up.: Connection
refused"

Details:

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/engine.py", line 588, in run_domain
    vm.startup()
  File "/usr/share/virt-manager/virtManager/domain.py", line 150, in startup
    self._backend.create()
  File "/usr/lib/python2.6/dist-packages/libvirt.py", line 300, in create
    if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)
libvirtError: monitor socket did not show up.: Connection refused

Restarting the system or the kvm-qemu service does not work and the
config files do not seem to be corrupted.
