And ignore the above! I was tinkering around with xenconsoled today - as
it doesn't seem to be included in the stock tarball but was added by
RedHat for the inital packaging I picked up.

It seems that it is critical to actually starting DomUs on boot - and
without it, they just sit there!

Does the same happen if you use xl vs xm? (chkconfig xend off && reboot)?
