Description Allon Mureinik 2014-01-23 07:50:40 UTC

Description of problem:
The first step in Storage Live Migration is to take a live snapshot, which currently (oVirt 3.4) snapshots all the VM's disks.
This is of course redundant, and only the disks being migrated should be snapshoted.

Version-Release number of selected component (if applicable):
3.4.0-beta-1

How reproducible:
100%

Steps to Reproduce:
1. Create a DC with compatibility version of at least 3.1
2. Create a cluster
3. Create a host in the cluster
4. Create two storage domains
5. Create a VM with two disks on storage domain A
6. Run the VM
7. Live migrate ONE disk to storage domain B

Actual results:
A live snapshot is taken with includes both disks

Expected results:
The live snapshot should include only one disk
