XEN VM + Block Device - Migration Paths?

Question

Xen

There is a XEN Hypervisor and N-virtual machines.
With fdisk -l I see a bunch of block devices tied to virtual machines. I want to transfer one of virtualok to other server. Accordingly, the question is how to copy a virtual machine (clone)?
PS - the mapper was also noticed, i.e. participation lvm.
ZZY - do not hit hard, I'm just mastering these questions.

Answer 1

Solved the problem myself.
Did the following.
In the console: lvs looked at the logical volumes. vgs looked groups.
Then with the command DD if=/dev/what_brought_vgs/what_brought_lvs of=/home/user/vm.qcow2
While the flight is normal. I'll try to start the virtual machine.
