Fedora xen - Mar 2006 - Problems with Xen + FC5 + Thinkpad

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hello all,

I recently upgraded from FC4 to FC5 on my Thinkpad T30 laptop and am looking
forward to playing with
Xen. However, I''ve hit a few stumbling blocks along the way. Following
the instructions at

http://www.fedoraproject.org/wiki/FedoraXenQuickstartFC5

I installed the Xen0 kernel and booted my system with it. However it hangs,
seemingly forever, at
the "Starting xend" stage. The OS seems ok as keypresses are still
printed to the screen, but
because the daemon never completes its startup process the boot sequence never
finishes. Upon
rebooting I noticed an error that gets printed while the kernel is loading,
which says that it could
not bind IRQ2 to guest because it is in use by cascade. This happens
consistently, so I wonder if
it''s a hardware problem?

I booted the system into single user mode and chkconfig''d xend off,
booted normally and attempted to
start the daemon post-boot. It printed a message about starting the Bridged
Firewall, which I had
not seen during bootup, but still seemed to hang indefinitely.

Oh, and SELinux is loaded but not enforcing. Should that be sufficient?

Does anyone have suggestions for how I might further troubleshoot this?

Thanks,
- --Brad

Following the instructions at
  Try to make a clean install to make sure you really have all FC5 bits.
You can check /var/log/xend.log for hints on what''s going wrong.

Did you do the part about updating grub to include ''init 3'' to
disable X? If
so, go back and delete the ''init'' (you just need
''3''). This fixed the dom0
kernel hang I had.

I asked someone in the #fedora irc channel to fix this, but it''s still
there.

If anyone can fix it, it also needs to be fixed on 
http://www.fedoraproject.org/wiki/FedoraXenQuickstart

Please open a bugzilla for this so we can look into it.  There is
nothing fundamentally incompatible between Xen and X: my Xen desktop,
running X, had an uptime of over 8 days when I shut it down earlier
today.  init 3 is *not* needed in general; if you have a specific
hardware config that isn''t working under Xen with X, then
that''s
something that needs debugged.

Thanks,
 Stephen

Note that I wasn''t complaining about X, which does work, but about the
wiki
page suggesting to add ''init 3'' to the boot args to boot into
run level 3.
That''s wrong, and causes the kernel to hang on boot. A simple
''3'' is needed to
boot into run level 3.

Still want a bug report? It should be fixed, because a newbie isn''t
going to
know this, and will think xen doesn''t work.
