I have a FreeNAS server I have been running since version 7 and love it. I use it with Duplicati to backup about 45 local and remote machines via SSH and it just....works. We just received in a 2012 R2 Datacenter server that the server guys wanted, but it only has 2 148GB drives (with 128GB of RAM, go figure). So the question came up if they can store the VM's on FreeNAS (I have about 16TB free). Is this a good idea or a BAD IDEA. If it works, they would store and load the VM from FreeNAS and just use the server as a head end. Since I have never tried to host a VM (or even a CIFS share) I just wanted to ask for an opinion from those that may have been down this road.
