Description Mark McLoughlin 2011-09-22 06:12:29 UTC
On Fedora we have a libvirt-guests service which saves running guests on shutdown

If I reboot a compute node, the guest gets saved and then I try and terminate it, I get:

(nova.exception): TRACE:   File "/usr/lib/python2.7/site-packages/nova/compute/manager.py", line 502, in terminate_instance
(nova.exception): TRACE:     self._shutdown_instance(context, instance_id, 'Terminating')
(nova.exception): TRACE:   File "/usr/lib/python2.7/site-packages/nova/compute/manager.py", line 493, in _shutdown_instance
(nova.exception): TRACE:     self.driver.destroy(instance, network_info)
(nova.exception): TRACE:   File "/usr/lib/python2.7/site-packages/nova/virt/libvirt/connection.py", line 293, in destroy
(nova.exception): TRACE:     virt_dom.undefine()
(nova.exception): TRACE:   File "/usr/lib64/python2.7/site-packages/libvirt.py", line 1197, in undefine
(nova.exception): TRACE:     if ret == -1: raise libvirtError ('virDomainUndefine() failed', dom=self)
(nova.exception): TRACE: libvirtError: Requested operation is not valid: Refusing to undefine while domain managed save image exists
(nova.exception): TRACE: 

If this happens, Nova could do a virDomainManagedSaveRemove()

For now, we can just recommend disabling libvirt-guests
