This is a little tricky as migration ties into DNS hostname resolution (as nova/libvirt use an unqualified hostname as the target for a migration).
Can you confirm which of the IP addresses on the host the <HOST> name resolves to? That might give us a clue as to what's happening here.
FTR "unit-get private-address" is not consistent, so we're moving the charms over to using network-get when deployed with Juju 2.0, which should ensure we at least get some sane behaviour in this respect.
