xen discuss - Jan 2010 - CentOS 5.3 domU works, 5.4 doesn''t work

Greetings,

My install procedure looks like this:

pfexec /usr/sbin/zfs create -V 5gb tank/mydom

pfexec virt-install \
  --file=/dev/zvol/dsk/tank/mydom \
  --location=http://mirror.anl.gov/pub/centos/5.3/os/x86_64/ \
  --mac=00:16:3e:01:09:91 \
  --nographics \
  --name mydom \
  --os-type=linux \
  --paravirt \
  --ram 256 \
  --vcpus=1

I run through the text-based CentOS installer, pretty much taking the defaults
all the way through, and everything works well.

With CentOS 5.4 (changing only the version number in the location URL above),
things fall apart.  The install runs smoothly, but when the domU gets rebooted,
I have the following result:

insmod: error inserting ''/lib/dm-raid45.ko'': -1 Unknown symbol

Kernel panic - not syncing: Attempted to kill init!
 libvir: Xen Daemon error : GET operation failed:

...Actually, there was a lot more noise than that.  I''m not sure how
much of it is meaningful.  The whole output is here: 
http://vm.marget.com/CentOS_5.4_error.txt

What am I doing wrong?

Also, am I doing the right thing with installing grub on the domU''s
MBR?  My prior xen experience involved keeping the kernel outside of the domU
disk.  This pygrub business is all new to me.

Thanks very much.

I''m beginning to suspect the mirror I used for the CentOS installation.

The failure I cited previously was 100% repeatable.  I did the install several
times, with the same result.

Since then, I''ve rsynced my own CentOS 5.4 mirror directly from CentOS.
Installs from my own HTTP server, running on Dom0 work perfectly (in addition to
running much faster).

No problem, I guess!

Are you using Opensolaris B133 PV drivers?

I can''t seem to get it to work because it doesn''t recognized
my disk and network drivers.

How do I go about fixing it?

Thankx.
