[rhelv5-list] Xen filesystem mounting errors



I have configured a Dell Power Edge 2950 with RHEL 5.1 set up for virtualization.  Xen version is 3.1

I set up my Xen config with tap:aio storage.  My disk line in my guest config is:

disk = [ 'tap:aio:/var/lib/xen/rhel5guest1.img,xvda1,w', 'tap:aio:/var/lib/xen/rhel5guest1.swap,xvda2,w' ]

Both xvda1 and xvda2 files were set up following xen.og documentation.  Attempting to boot my first guest failed on "switchroot:mount failed".  Reading more documentation and Web posts, it looked like the error was in my initrd file.  I built 3 different initrd's, excluding different combination of modules.  Here are my results for each different one:

So near and yet so far.  Any suggestions?  Is initrd the culprit, or perhaps something else?
