Xen host == the physical machine running the hypervisor, the privileged domain 

Xen guest == the virtual machine, vm. 
             Also called as "unprivileged domain", 
             or domU in Xen talk.

host/guest is the usual/common usage.. for example VMware uses the same naming.

So yeah.. what's the problem actually? You just copy the Xen guest cfgfile 
from /etc/xen/<guest> to the new host, and also transfer the disk image contents
to the new host.

Then you're ready to start the guest in the new host.
