Hello experts,

I have a network topology like this diagram.
When start live migration moving a VM from Host A to B,
the migration process uses either 10G=
bE (10.0.0.1) or 1 GbE (10.0.0.2),
but the user cannot specify the source NIC by current migrate command.

To solve the problem, my rough idea is to add a source ipv4:port a=
rgument,
the migration command see=
ms like
```
migrate -b tcp:10.0.0.1=
:4444 -d tcp:10.0.0.3:4444.
```

Is it an available s=
olution? Or, is there any concern and sugesstion?
Besides the idea, is there any good way to this issue?
