It did not have the mbox driver compiled in, I had to enable it in the xen .config

Use the -xen kernel and build an initrd -- it has drivers for most

Watching the bootup closely and comparing it to a normal boot I noticed the LSI megaraid drivers are never started up.

Does xen have megaraid_mbox support?

It boots up, loads the xen-3.gz, scrubs memory but when it goes to load the root LVM claims it can't find VolGroup00
