Fixed In Version: openstack-nova-2013.2.1-4.el6ost
Doc Type: Bug Fix
Doc Text:
Previously, rebooting a host caused all its instances to stop and change to the SHUTDOWN power state. The unpause action was only allowed on instances with PAUSED power state. As a consequence, it was impossible to unpause/start/reboot an instance that had been paused before the reboot. As it makes no sense to unpause an instance once it has been stopped, a check has been added in a periodic task that will fix the state and stop instances that are in SHUTDOWN/CRASHED power state but are still in the PAUSED state. As a result users can now start those instances again, preventing them from being stuck in an inconsistent state.

Description of problem:
Unpauseing an instance fails if host has rebooted.

How reproducible:
Every time 

Steps to Reproduce:
1. Boot an instance 
2. Pause that instance
3. Reboot host
4. Unpause instance  

Actual results:
can't unpause instance stuck in status paused, power state - shutdown

Expected results:
Instance should unpause, return to running state

Additional info:

virsh list -all --managed-save 
ID is missing from paused instance "-" (pausecirros), state -> shut off.

Testing without rebooting host, ID/state ("1"/paused) instance (cirros) are ok and it unpauses ok.
