After reading the info on http://www.aisecure.net/2011/03/26/cloning-a-zfs-bootable-system/ I might be doing that. Sounds not too difficult and it is not really a problem to have ZFS on the virtual machine. It runs good enough, at least solaris 11 runs smoothly as a VM.

Dump Restore on ZFS root system
I run a ZFS on root FreeBSD system. I know I can backup with snapshots but I want a dump/restore action because I want to transfer this system to a UFS virtual FreeBSD machine.
