i've done some debugging to /usr/sbin/xend and this is what i came up with:
from /var/log/xen/xend.log:
[2010-04-15 10:50:16 32442] ERROR (SrvDaemon:356) Exception starting

the file which it's trying to parse is /var/lib/xend/state/host.xml,
which is empty.
which service/module creates this xml file? do i need to edit it?
thanks!
