[Fedora-xen] rawhide guests on F-8 host

I just build a F-8 x86_64 guest on a F-8 x86_64 host, then did a yum 
upgrade to rawhide.  Now the domain will not start.  Is this expected?

	Thanks for reporting, I can reproduce here. Try this older kernel for
now:

  http://koji.fedoraproject.org/koji/buildinfo?buildID=32046

	More details filed here:	

  https://bugzilla.redhat.com/show_bug.cgi?id=434556

	FWIW, I got this stack trace by setting the "on_crash" action for the
guest to "preserve" and then when it had crashed, I did:

  $> /usr/lib64/xen/bin/xenctx -s /boot/System.map-2.6.21.7-2895.fc9xen 1

Cheers,
Mark.

Is there any way to install this into my currently dead domain?

	Well, hopefully you still have the F-8 kernel installed and you can
just run that e.g. by doing "virsh console foo" before the grub
timeout
expires and choosing the older kernel.

	Alternatively, you could mount the /boot partition and change the
default in grub.conf e.g.

  $> losetup /dev/loop0 /xen/foo.img
  $> kpartx -av /dev/loop0
  $> mount /dev/mapper/loop0p1 /tmp/foo
  $> emacs /boot/grub/grub.conf
  $> umount /tmp/foo
  $> kpartx -d /dev/loop0
  $> losetup -d /dev/loop0

	Once you''ve booted with a working kernel, then you can upgrade to the
newer one.

	If you don''t have any working kernel in the domain, you could try
something like this:

  $> losetup /dev/loop0 /xen/foo.img
  $> kpartx -av /dev/loop0
  $> vgscan
  $> vgchange -ay VolGroup00
  $> mount /dev/VolGroup00/LogVol00 /tmp/foo
  $> mount /dev/mapper/loop0p1 /tmp/foo/boot
  $> chroot /tmp/foo yum --nogpgcheck localinstall kernel-xen-...rpm
  $> chroot mkinitrd --with xenblk -f /boot/initrd-2.6.21.7....rpm
2.6.21.7...
  $> umount /tmp/foo/boot
  $> umount /tmp/foo
  $> vgchange -an VolGroup00
  $> kpartx -d /dev/loop0
  $> losetup -d /dev/loop0

	Or maybe easier, boot the dead domain with a rescue CD.

Cheers,
Mark.
