} They are all identical (I think I never had xentools installed before).
} 
} I notice a strang message in the dom0 at startup:
} 
} TDB: tdb_open_ex: could not open file /var/run/xenstored/tdb: No such file or directory

     This can be ignored.  The file will be created if it doesn't
exist.  It's mostly a warning and the code should probably be
changed to only print this message in a debug/verbose mode.  But,
that is something that upstream should do.

} but when I look there later, it exists. And:
} 
} WARNING: Failed to open connection to gnttab

     This can be ignored.  It seems that we don't have code for
modern gnttab.  It doesn't seem to hurt anything, but we should
probably fix it some day.

     Looks like you can just add 'xendomains=""' to /etc/rc.conf.
The script starts with:

        [ -n "$xendomains" ] || return

We should probably change it not to bomb if $xendomains isn't set.
