<br>
we're installing a small ovirt cluster for hosting some test<br>
environments at work. We're interested in testing VM running<br>
hypervisors (i.e ovirt itself or a small openstack deployment).<br>
<br>
Is there any documentation showing how to enable nested virtualization in ovirt?<br>
<br>
I've seen that while adding an host to the cluster there is the<br>
opportunity to flag "Nested Virtualization" option, but i didn't<br>
understand if other packages and configs are required.<br>
<br>
Our environment is running latest ovirt 4.1 installed with ovirt-node-ng.<br>
