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
