Description of problem:
Live storage migration failed because live snapshot is not supported for the host as reported here https://bugzilla.redhat.com/show_bug.cgi?id=1158043.
After the failure, the image remains stuck in status LOCKED.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
On a setup with a DC with more than 1 storage domaim from the same type (block/file)
1. Add a RHEL6.6 host with the mentioned qemu-kvm-rhev version to RHEVM, check that it does not support live snapshot
2. Create a VM with disk attached on one domain
3. Try to live migrate the disk to the second domain
The LSM fails:

But the disk remains in status LOCKED:

Disk should move to status OK after a failure to live migrate it

This is not the same scenario. Please read description. The image remains in LOCKED state after engine blocked the LSM on CDA.
Anyway, the other bug was verified based on the same vdsm build this bug was opened with:
Comment 24 Nikolai Sednev 2014-10-28 10:17:09 EDT
Works for me on these components:
On my host:
[root@green-vdsb ~]# rpm -q vdsm
The security flag was set by mistake. It will be removed
oVirt bug 1105846 should handle this, leaving this one open for verification on RHEV.
Anyway, reducing priority to low - once bug 1149460 is solved, this problem can never happen anyway.
The LSM process completed successfully, and the disk status was set back to "OK"
Verified on VDSM vt11
RHEV-M 3.5.0 has been released, closing this bug.
