Hi,

rsync works great on production enviroments, I had paravirtualized some servers with these method:

rsync -ave ssh --exclude=/proc --exclude=/sys --exclude=/dev (if you are using udev) root@runingserver:/ /mnt/newserverimage/

after this:

mkdir /mnt/newserverimages/proc

mkdir /mnt/newserverimages/sys

mkdir /mnt/newserverimages/dev

review your fstab, and copy the kernel modules:

cp -pr /lib/modules/2.6.16-xenU /mnt/newserverimages/lib/modules/

more or less .... this is the way

Also I have full virtualitzed some old GNU/Linux boxes with kernels 2.4, I used GNU/Linux live CD on the old box and dd utility:


dd if=/dev/hda | ssh root@xxxxxxxxxxxxxxxxx "/bin/dd of=/dev/vg00/newvserver"

I hope it will be helpfull


Marc
