Re: [ovirt-users] Nested KVM for oVirt 4.1.2

Hi, Hosted engine runs as VM on one of the hosts. But not necessarily on the first one (it can even move if it decides so). Well you can always run the engine on a physical node directly too. The question is why would you want that when hosted engine gives you fail-over and reliability features. So I would install Node on all four hosts, enable all of them for hosted engine and enable three of them for Gluster if hyperconverged is what your want.
