Live storage migration does not support concurrent migration of disks from a single virtual machine. Instead live migration of each disk attached to the virtual machine must be manually initiated in serial.

Description of problem:

I tried moving a second disk while the first disk was still moving (snapshot has already been created) and failed to move with CanDoAction: 

2012-11-04 17:04:25,421 WARN  [org.ovirt.engine.core.bll.MoveDiskCommand] (ajp-/127.0.0.1:8702-9) CanDoAction of action LiveMigrateDisk failed. Reasons:VAR__ACTION__MOVE,VAR__TYPE__VM_DISK,ACTION_TYPE_FAILED_DISKS_ARE_LOCKED,$diskAliase
s DAFFI_Disk1


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

si23

How reproducible:

100%

Steps to Reproduce:
1. run a vm with multiple disks
2. move one disk
3. once the first snapshot was created try to move the second disk
  
Actual results:

we fail with CanDoAction:

2012-11-04 17:04:25,421 WARN  [org.ovirt.engine.core.bll.MoveDiskCommand] (ajp-/127.0.0.1:8702-9) CanDoAction of action LiveMigrateDisk failed. Reasons:VAR__ACTION__MOVE,VAR__TYPE__VM_DISK,ACTION_TYPE_FAILED_DISKS_ARE_LOCKED,$diskAliase
s DAFFI_Disk1

Expected results:

since we are working with multiple domains I would expect that a locked disk should not block me form moving a second as long as the first snapshot was already created.
