NOTE that minimal command to migrate vz domain is like next:
virsh -c vz:///system migrate 200 vz+ssh://shiny0/system --p2p
--live --compressed --persistent --undefinesource
Difference from v4:
1. move preparation of the migration uri from src to dst as dst intended to do it.
2. change hypervisor migration scheme from 'tcp' to 'vzmigr'
3. declare this scheme in host caps
