In this section....
# mount both LVMs
mount /dev/mapper/VolGroup00--LogVol00 /mnt/oldroot
mount /dev/mapper/VolGroup00--LogVol01 /mnt/newroot
The system tells me that I need to specify the file system type. For the life
of me I cannot determine the file system type. Any hints would be appreciated.
Thanks!

another domU?
Hi Rudi,
# create two directories for mount points
mkdir -p /mnt/oldroot /mnt/newroot
# create the 30G LVM
lvcreate -L 30G -n VolGroup00-LogVol01 /dev/VolGroup00
mkfs -t ext3 /dev/VolGroup00-LogVol01
# mount both LVMs
mount /dev/mapper/VolGroup00--LogVol00 /mnt/oldroot
mount /dev/mapper/VolGroup00--LogVol01 /mnt/newroot
# sync the data
rsync -au /mnt/oldroot/* /mnt/newroot
Alternatively use cp -ax as described in the Xen manual.
#unmount partitions
umount /mnt/oldroot
# change networking on new domU
chroot /mnt/newroot
edit /etc/hosts, /etc/resolv.conf, /etc/sysconfig/network,
/etc/sysconfig/network-scripts/ifcfg-*
exit
umount /mnt/newroot
Hope the syntax is right, but you get the idea...
