Description Oded Ramraz 2011-07-10 11:24:05 UTC

Description of problem:

I created a VM from template X,  then i removed the disk from the VM and added a new one and reinstall it with new OS. 
When trying to remove the template X i got an error message which tells me that i can't remove the template because VM's are still attached to it. 
This restriction is not logical since the VM is not derived from that template anymore. 

IMO when removing the last disk from a VM BE should clear its template field and enable to remove it.

Consider this scenario:
1.Create a VM X
2.Create template T from VM X 
3.Remove the disks from VM X and install new OS on it.
4.Try to remove template T 
You can't do that since the still Backend thinks that the VM is created from that template . 

This bug is quite annoying and i encounter it several times already .
