Re: [Xen-users] Is it possible to copy the contents of one domU to 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...

Hi all

I hope this can be solved.

I have a 50GB CentOS domU, and I want to copy the contents of the domU to another domU, of smaller size (30GB) - is this possible?
