Sorry to spam the list, but here's some more information about what I

There's a little difference if LocalServer is running rsync at full
speed or that the domU's are idle. But that's IMO quite logical that
network traffic and disk I/O increases load on dom0 as well.

However that consumption feels quite high, based on the feeling I got
from reading this list, documentation etc. There's no other services on
dom0 besides the "normal" things (exim4, sshd etc).

I started to suspect about the hardware itself as well, but sensors,
hddtemp and others doesn't show anything special and memory is ECC
enabled and tested prior dom0 installation.

That said, the system hasn't crashed so far with dom0-min-mem 512
- -option, but the system has ran only an hour with that setting without
any significant load, except the rsync -session.
