Re: [Xen-users] Xen 3.0.0 + RAID + LVM + CentOS = problem

["Bill Church" <bill.church@xxxxxxxxx>]

I too am having a similar issue. It actually occurred with and with out LVM,
the common denominator was Software RAID 1. I used both the RPM install and
the scripted RPM install. I also rebuild the initrd just to make sure it
wasn't missing something, but as you can see in the dmesg it looks like it's
picking up the modules/drivers for everything. Running CentOS 4.2 and
everything boots find with the standard kernel. Hardware is a Pentium 4 D
3.0MHz, Intel 945G chipset, dual SATA Hatachi Drives, and 4GB ram,  if any
of that matters.

Any help would be greatly appreciated, I'd consider going over to Fedora if
I thought it would matter but I'm thinking it probably wont.

Here's the output of my DMESG:
