You might need to restart your guests and/or toolstack after starting
xenconsole.

This should all have been taken care of by the initscripts shipped with
xen -- are you not using them for some reason?

Ian,

   Do initscripts here refer to the xen-related scripts under /etc/init.d/ ?
   Like xencomms?
   I've actually used xencomms and xend, also I reinstalled the domU (f13 here).
   However, the issue is still there.
Could you please take a look at the following running script and see what is the problem here?

Domain installation still in progress. You can reconnect to
the console to complete the installation process.
