Your intention is to have hosts with a different CPU level (older) in 
the second cluster. And these hosts will be used to run VMs, IIUC. So 
you only need to Enable Virt service.

Regarding your question, on if the 2 clusters can share the same gluster 
storage domain - I don't know the answer to this.
Nir, Allon - is this supported?
