[ovirt-users] minimum DNS requirements for /etc/hosts

So like the nut job I am, I host my dns server on a virtual machine that is now hosted by ovirt, I also have a few gateway machine in there as well for routing traffic between internal networks. With virt-manager, DNS rarely seemed to be an issue. I'd connect to a host IP, and bring up the vm, no problem. Ovirt on the other hand takes forever if dns is down. So i've passed around a /etc/hosts file to resolve any ip address that ovirt might be looking for while dns is out. I'd like to verify at an abstract level, what needs to be in said file, to keep everything from timing out, or just taking forever. name and FQDN of each host name and FQDN of engine host name and FQDN of each storage domain. Is this enough, or are there other places/things the ovirt node and hosts might be trying to resolve? thanks, -jj-
