Description Timothy St. Clair 2009-10-23 12:27:04 EDT 
When you restart libvirtd on an execute machine which is running KVM || XEN jobs then the vm-gahp will continue on forever even though it has lost communication to the vm, and libvirtd has terminated the vm.

Comment 3 Luigi Toscano 2010-05-31 11:08:47 EDT 
This bug is linked to some issues of libvirtd, which does not support restarting properly when there are running images at least on RHEL5.x with KVM technology (Xen seems to work). When libvirtd is restarted, the VM is leaked.

The new code promptly recognizes that libvirtd does not see the VM anymore and terminates the job. It does not change Xen behaviour, which still work after the restart.

Verified on RHEL 5.5, KVM/x86_64, Xen/i386, Xen/x86_64.
