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.
