oVirt-node is not installed "on an OS", its an image you install on bare 
metal. ovirt node is a trimmed down .el6 with the necessary packages to 
be managed by ovirt.
you can choose to use normal .el6/fedora, and use them as hosts via the 
engine gui, it will deploy/configure these packages as well.
