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 10GbE (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 argument,

the migration command seems like

```

migrate -b tcp:10.0.0.1:4444 -d tcp:10.0.0.3:4444.

```


Is it an available solution? Or, is there any concern and sugesstion?

Besides the idea, is there any good way to this issue?
