[Bug 1611042] [NEW] failed-to-delete-instance-lxc-with-lvm

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

Description:
------------
When using lxc libvirt driver, nova encounters error in deleting an instance (nova delete). The instance is not deleted from nova. However, virsh list shows that the domain is not running after nova delete completes.


Steps to reproduce
--
libvirt_type=lxc to choose LXC as hypervisor type
libvirt_images_type=lvm to choose LVM as imagebackend store

nova boot container1
nova boot container2
nova delete container1
virsh -c lxc:/// list (to see what happens of the domain from point of view of libvirt).

Expected result
--
Nicely destroy container and remove LVM disk

Actual result
--
Nova encounters error in deleting container
