Title:
Resource could not be updated when deleting instances
Status in OpenStack Compute (Nova):
Fix Released
Bug description:
In my openstack compute node. a kvm-based vm exists and it has a iso image
configured in the cdrom. The iso image path is
/root/RHEL6.5-20131111.0-Server-x86_64-DVD1.iso.
When deleting the nova instances, the following error happend in the
/var/log/nova/compute.log. And this error caused that the resources could not
be updated and the resources occupied by the deleted instances could not be
released. This error also happend when restaring the nova-compute service and
so that nova-compute could not restarted successfully.
We should catch this exception for some existing libvirt instances
otherwise all resources for nova instances could not be updated
correctly.
