Open Stack

Hi all,
i have a mission to migrate vm from an old Openstack environment to a
new some days ago, then i export the information of vm from
database(nova、neutron、cinder..). After that i just went to copy the
vm's disk and the xml format config file of libvirt.

in my mind it's will be much easy through a function which can pack the
vm's informations and files and finally just export as one record(such
as one json message).

use the record i can migrate the vm like what vmware would do: i can
quickly see it and boot it soon when i import the record to the new
environment.

thx for any help!
