[xubuntu] FreeNas as a KVM guest?

Hi,

Looking to try out FreeNas, which is based on FreeBSD.

Before I buy hardware, I was wondering if I could reasonably build it as a KVM guest first.

I'm a KVM novice. I've had VMware and Parallels experience as a developer before, and I've used a few different Linux virtualization schemes before.

I'm using an i7 quad core with the main OS on SSD and the vms on an hdd if that matters.

Thanks.

P.S. Oh yeah, I'm using xubuntu 13.04
