Description of problem:

Suspend to VM that has only direct LUN disks is failing with 'CanDoAction of action HibernateVm failed' from engine. There is an active storage domain in the pool so there is a place where the VM state can be save to. Therefore, there should not be a problem with VM suspension.   

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

rhevm-backend-3.2.0-10.16.master.el6ev.noarch
vdsm-4.10.2-12.0.el6ev.x86_64

How reproducible:

100%

Steps to Reproduce: In a iscsi/FC DC with one or more host(s) and an active storage domain: 

1. Run a VM with only direct LUN disk
2. Suspend the VM
  
Actual results:

The action is failing with "Cannot suspend VM that has no image disks." in the UI and:

2013-03-27 18:30:38,035 WARN  [org.ovirt.engine.core.bll.HibernateVmCommand] (ajp-/127.0.0.1:8702-3) CanDoAction of action HibernateVm failed. Reasons:VAR__TYPE__VM,VAR__ACTION__HIBERNATE,VM_CANNOT_SUSPEND_VM_WITH
OUT_IMAGE_DISKS


Expected results:

There is a place where VM state can be save to (the active storage domain in the pool), so Suspension to VM with direct LUN disk should work.

Additional info:
see logs attached.
Comment 1 Omer Frenkel 2013-03-28 13:29:38 UTC 
this was caused because of the fix for Bug 841504
I don't see a reason to block suspend for vm without image disks as done there
