[ovirt-users] 3.6: updating a template in a vm pool causes removal of soundcard and memory ballon device

[Cristian Mammoli]

Hi, when I change template version in a vmpool the souncard and balloon 
device get cleared, even if the new template has sound and ballon enabled.
After that the checkbox are greyed out and cannot be enabled without 
destroying and recreating the pool...

How to reproduce:

Create a template with soundcard and memory ballon device
Create a pool from the above template
VMs and the pool itself have sound and balloon device

Create a new Template as version 2 of the original one
Check that sound and balloon are enabled in the template
Reconfigure the pool to use version 2 of the template
VMs and the pool itself have sound and balloon *unchecked* and cannot be 
enabled anymore
