I remember that during my previous attempts ZFS ate most of my machine's memory (dom0 was too small I think) and the symptom was very similar if not identical. One thing which struck me is that I was able to fully but one Linux HVM domU. I am also toying with OpenFirmware which boots from floppy as a HVM guest. > Have you checked if you need to change your /etc/fstab to correctly point > to the new device?

"?" does not work - it mostly causes a panic, the console is slow, but I managed to switch it to /dev/ada0p2, dmesg below: Copyright (c) 1992-2016 The FreeBSD Project.
