Comment 11 for bug 1382046

I find that I need to restart libvirt-bin multiple times in order to be able to reliably use virsh. Once will usually get virt-manager up and running, but attempting send-key from the command line will start to fail again:
% virsh send-key Windows7 29 56 111
error: failed to connect to the hypervisor
error: no valid connection
error: Failed to find group record for gid '1001': No such file or directory
