Hmm, it does not help.
But I'll need to double check if I was misleading you.
I used attempt dom0pvh=1 but it was too unstable and I was only able
to disable it through hacking grub.cfg through sshfs remotely.
I forgot to touch the /etc/default/grub so the dom0pvh=1 may have come
back when I was generating the log yesterday.

Going to do it once again now.
