log and screen shot
Description of problem:
I wanted to live move disks but there is low storage space on my domain.
the live migration and the failure are both not reported in event log.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. create a VM with preallocated disks leaving only 10% free space on your domain
2. run the vm
3. try to live move the disks to a second domain.
the live migration will fail with CanDoAction but the event log is not reporting failure.
we should report failure
Additional info: log
2013-01-20 13:09:57,276 WARN [org.ovirt.engine.core.bll.CreateAllSnapshotsFromVmCommand] (pool-3-thread-45) [71c03db8] CanDoAction of action CreateAllSnapshotsFromVm failed. Reasons:VAR__ACTION__CREATE,VAR__TYPE__SNAPSHOT,ACTION_TYPE_F
IMHO, adding this new event should is more storage related (i.e - providing new event in storage flow of live storage migration).
Currently, we only fire such a audit log msg as a result of polling storage domains, not in CDA.
Resetting devel-ack until further discussion with qa/pm
