Betreff: Re: [Xen-users] Guest-domain has no login [SOLVED]

Hi Trilok,

thanks for the quick reply. It worked :)

but I had to comment out another line (because the init-routine compplained about a double "co" entry.) For anybody having the same strange behaviour and looking for a solution, heres my /etc/inittab of the guest domain (including
the comment out line):

as this is my first post I want to say hello to everybody.

Well, and unfortunatly I've already got a question for you:

I've installed a guest domain (OS: CentOS 4) on my xen-machine and
it's para-virtualised (just to provide the information ;) ).

After the installation and mount the image containing the guest to copy
the necessary modules for the xen-kernel, umount it and boot the
guest domain with
the xen-kernel. Everything seems fine except that udev seems to not
create any
console/tty or similar. Heres a snipped of the boot log:

===

There are some error-messages which compplain about not finding any
consoles.
I would normally try to make some new ttys with mknod but
unfortunatly I can't
even login to the quest, after the last line the guest seems to hang
(the last two
lines beginning with "INIT" appear after a short time (about 2mins or
something)).

I've already searched here at the mailing list without success. I
hope I do not double post
a problem which is already known and solved (in this case maybe would
somebody post me the link
to the solution?)


Thanks i advance for any help.


Best Regards,
  Marcel
