Comment 4 for bug 1671288

@loganv, @gyurco the change was made in that patch series https://review.openstack.org/#/c/410817
and first started with adding live_migration_inbound_addr in https://review.openstack.org/#/c/245005/.

I didn't know about the case with qemu+ssh you proposed.
An inconvenient workaround here is to use ~/.ssh/config for additional options, though it's per host.

Possibly, @johngarbutt, @stephenfinucane could add some details.
