[Xen-users] Upgrading to Xen 3.1.0 Dom0 on Centos 5

["Brent Meshier" <brent@xxxxxxxxxxx>]

During boot LVM complains that it can't find /dev/VolGroup00/LogVol00 and
results in a kernel panic.  I'm using Dell 1950's with Dual Xeon 5245's CPUs
and 32GB RAM with the megaraid_sas kernel module.  I've tried downloading
the x86_64 binaries and creating an initrd with mkinitrd to load the
necessary modules using this command:

mkinitrd -v -f --with=megaraid_sas /boot/initrd-2.6.18-xen.img 2.6.18-xen

>From what I can tell at boot, it's either not loading the megaraid_sas
module or at least not correctly.  Here is a screenshot:

On a side note, I thought it might be easier to build from source RPM, but
apparently there is no support:

/usr/bin/rpmbuild --rebuild xen-3.1.0-1.src.rpm
Installing xen-3.1.0-1.src.rpm
error: Architecture is not included: x86_64 

So any ideas why it won't mount root?
