Public bug reported: I have an LXC compute node. I can create LXC containers, they work fine. When I try to reboot containers (reboot initiated from inside the container), the container goes into "SHUTOFF" status / "Shutdown" power state, and does not come back.
If I do a "nova start", the container comes back to "RUNNING", but with the following exception in logs: ---------- ERROR nova.virt.disk.api [req-63630337-923f-4994-8960-83368c6a192e admin admin] Failed to teardown container filesystem TRACE nova.virt.disk.api Traceback (most recent call last): TRACE nova.virt.disk.api File "/opt/stack/nova/nova/virt/disk/api.py", line 472, in teardown_container TRACE nova.virt.disk.api run_as_root=True, attempts=3) TRACE nova.virt.disk.api File "/opt/stack/nova/nova/utils.py", line 389, in execute TRACE nova.virt.disk.api return RootwrapProcessHelper().execute(*cmd, **kwargs) TRACE nova.virt.disk.api File "/opt/stack/nova/nova/utils.py", line 272, in execute TRACE nova.virt.disk.api return processutils.execute(*cmd, **kwargs) TRACE nova.virt.disk.api File "/usr/local/lib/python2.7/dist-packages/oslo_concurrency/processutils.py", line 275, in execute TRACE nova.virt.disk.api cmd=sanitized_cmd) TRACE nova.virt.disk.api ProcessExecutionError: Unexpected error while running command.
