Hi all,
     I have installed xen on the computer, and adopted LVM as domU's
storage devices. I have installed a centos for the domU, now I want to
copy this system as another domU, Who can tell me how?

     Thanks a lot.

Best Wishes!

Hello,

Use "dd" for example :
dd if=/dev/mapper/origin of=/dev/mapper/clone bs=65536
You will need afterward to create a new VM definition file and modify
the machine name in /etc/sysconfig/network, /etc/hosts and with
"hostname newname".

Regards

JPPO

If you use dd (or better lvm snapshot) to get a copy from a runningdomU, use "xm pause" or "xm save" to copy the memory too.


Best Regards
