I am sorry, perhaps it wasn't clear enough.

I mean the domU successfully restoring (and obviously, suspending 
properly in the first place) upon a dom0 suspend/resume cycle.

For instance, with QubesOS, which is Linux/Xen based, all virtual 
machines resume working normally after suspending and resuming the machine.

I am considering FreeBSD for a home project, and it requires 
virtualization (jails not enough).

Because it makes no sense to keep the machine on 24/7 in this scenario, 
and because it would be cumbersome to shutdown the machine every night, 
I am looking for the possibility of suspending/resuming.

I know this works with a Linux dom0 and at least Linux domUs.

My preference is FreeBSD dom0 and domUs.

But if FreeBSD dom0 fails to suspend/resume and domUs work, I might 
consider (reluctantly) Linux for the dom0 role.
