I think rather than having it popup a new window with a list of hosts to
migrate to, you could just have a sub-menu where you choose the destination
host directly.

eg,

    right-click
      |
      +-  Run
          Pause
          Shutdown
          --------
          Migrate ----> host1.example.com
                        host2.example.com
                        host3.example.com
                        ...etc...

When the user selects one of these hosts, it'd popup a confirmation
window, and do the neccessary migration checks, and then allow the
admin to confirm to start the migration.

Yes, checking for name/uuid uniqueness has to be done inside libvirt by
each hypervisor driver according to their own rules.

virt-manager will need to check the kind of things on the TodoPreMigrationChecks
wiki page.
