Installed a RHEL6.0 virtual machine, install went fine. The install rebooted at the end, the virtual machine window hung, the virt-manger window hung, let them sit for 5 minutes or so then killed them. Have 2 other old virtual machines that continued to run. Tried to start the new machine:
virsh # start lark-virtx
error: Failed to start domain lark-virtx
error: Timed out during operation: cannot acquire state change lock
Stopped librvirtd:
service libvirtd stop
Removed run directory:
rm -rf /var/run/libvirt
Note after the shutdown there was no /var/run/libvirt.pid file
Started libvirtd:
service libvirtd start
Was able to use virt-manager to start the new virtual machine.
I had the same problem.
Running RHEL5.6 host machine with latest patches as of today.

Thanks Adrian, that worked!
