Description of problem:
In F20, the default image format is qcow2 which allows user to create snapshots
of the VM. If you install a VM using virt-manager and create some snapshots,
you are not able to rename the VM.

The error message printed does not makes sense to me as a USER!

"Error changing VM configuration: Requested operation is not valid: cannot delete inactive domain with 2 snapshots"

I just renamed the VM and clicked apply. I as a user don't care what 
virt-manager is doing under the hood and should not be confronted with the 
internal process like "cannot delete inactive domain with 2 snapshots".


Version-Release number of selected component (if applicable):
virt-manager-0.10.0-5.git1ffcc0cc.fc20.noarch

How reproducible:


Steps to Reproduce:
1. install VM using virt-manager
2. create VM snapshots using virt-manager
3. try to rename the VM

Actual results:
you are not able to do it

Expected results:
I should be able to rename the VM regardless if it has any snapshots!

Additional info:
Error changing VM configuration: Requested operation is not valid: cannot delete inactive domain with 2 snapshots
