Hi guys,
I have been attempting to boot to Xen kernel for almost a week now,
and whatever I do results in pretty much the same.
Install attempts from pre-made RPMs, rebuilt RPMs from SRPM, source... same.
Would someone be kind and take a look at the following information
and advise me on what am I doing wrong?
-------------------------------------------------------------------------------------------
OS: CentOS 4.4, vanilla 2.6.9-42.0.3.EL kernel or 2.6.19.2 built from
oldconfig, whatever
Hardware: ASUS P4C800 motherboard, CPU Pentium 2.8 GHz (first one
from series, no HT), 2 plain ATA disks + IDE CD-ROM, 1.250 GB RAM
The box is fresh install, nothing on it, intended for Xen.

Whatever I do, pretty much same error(s):
mount error 6 mounting ext3
mount error 3 mounting none
switchroot mount failed 22
umount /initrd/dev failed
What am I doing wrong/missing to do? I may switch to Promise SATA +
SATA disks at some point, but I need to make it work on those plain
old ATAs to begin with.
I apologize for a long post to the list, I thought all that info may
be important. If additional info needed , please let me know.
If someone would be so kind to take a look and advise me on this, I
would really be grateful (not to mention saved :) )
Thanks in advance,
Boris
