This is up to you, but I would keep the image repository on the 
front end or eventually on the second system without VT. So you 
could use the two systems with VT as two identical cluster nodes.

Yes, and also on the front end.

It needs to be already mounted when OpenNebula will deploy a VM.

I am not sure about OpenNebula 3.0, but with 2.2 the image 
repository and also the VM_DIR folder need to be mounted in the 
same path as they are on the front end.
