Subject: [CentOS-virt] CentOS-6 KVM virt-manager will not shutdown guest
I have a CentOS-6 guest VM configured on a CentOS-6 host.
If I run virt-manager then I can start the guest VM but once it is running I
cannot get a shutdown command to have effect. To shutdown the running
guest I either must select Force Off from the Shut Down menu or open the
guest console and issue shutdown from the command line.

Is there some setting that is required to have Shut Down have effect when
issued from within virt-manager? is this a bug or a configuration problem?
When I issue the shutdown command to the guest then there is no entry
made in /var/log/messages. It just has no effect. However, if I issue a
reboot command from the same menu then I get an error:

libvirtd: 16:43:51.027: error: VirLibConnError 450 : this function is not
supported by the connection driver:
virDominReboot

Am I to infer that Reboot and Shutdown options actually are not
available to
use from the virt-manager Shut Down menu, notwithstanding that they are
present?
