vdsm.log from host in the affected data center

Description of problem:
Back end storage hosting the virtual machine experienced an unexpected outage causing a running VM to enter an unknown state.

Version-Release number of selected component (if applicable):
RHEV 3.0 Beta

How reproducible:
Unknown

Steps to Reproduce:
1.  Running VM
2.  Associated storage domain unexpectedly went off-line
3.  Hosted VM entered an "unknown" state and is unmanageable
  
Actual results:
Unable to start, stop, shutdown or delete VM.  Unable to execute a destroy on the associated storage domain.  

Utilizing the REST API to force VM delete results in the following error:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><fault><reason>Operation Failed</reason><detail>[Cannot remove VM. VM is running.]</detail></fault>

Command executed:
curl -X DELETE -H "Accept: application/xml" -H "Content-Type: application/xml" -u admin@internal:xxxxxx -k -d "<action><force>true</force></action>" https://rhevm3-beta:8443/api/vms/3461f1fe-d2a4-4f9f-beda-5e360967e8ba

Error when trying to execute a destroy action ont eh storage domain:
Cannot destroy Storage. Storage status illegal.

Expected results:
Expect through the management portal the ability to remove a defunct VM and/or it's associated storage domain.  REST API should also allow forceful VM deletion regardless of VM state.

Additional info:
vdsm.log attached.
Comment 1 Roy Golan 2012-05-21 11:07:52 UTC 

we can't destory a VM if we can't reachout to the domain to remove its disks but we do have auto-recovary that will make the domain and host responsive again (once outage ends) and this will let you manage the VM again.
