Ah hah, I answered my own question, I was looking in the wrong kernel
source tree (xenU rather than xen0). I compiled my kernel, make the
initrd, and got it all setup. Now the dom0 kernel seems to see the
SCSI (virtual SCSI) drive okay, but I've run into trouble in the next
step -- getting the filesystem mounted. It seems this kernel can't
read the partition table, and I suspect it has something to do with
the way newer versions of Red Hat label partitions.
This may be more of a Red Hat / Linux kernel issue than a Xen issue,
but does anyone have any ideas? The final messages on-screen leading
up to the failure are:
