There are 63(maybe 64) migration ports available. One nbd allocates one
port. So do we have at most 63 virtual disks in migration?
If so, I think it's not enough.
what about changing migrationPorts to remotePorts instead?
We only allocate one NBD port per domain, so two ports should be enough for
migrating 63 disks (one for NBD, one for the rest).
And the migration port range can be configured in qemu.conf.
