Autotest always uses "-incoming tcp:0:$port" to start dest vm,
and migrate with "migrate -d tcp:localhost:$port",
or "migrate -d tcp:$dest_host:$port"
Upstream qemu already supports IPv6 migration, current autotest
would fail to migrate in localhost.
'localhost' has multiple aliases (::1 and 127.0.0.1) in /etc/hosts.
getaddrinfo() returns an address list, "::1" is the first item
of the list, "127.0.0.1" is the second item. First available
addr will be choosen to connect. But "0" will be parsed to 127.0.0.1
It caused localhost migration fails, multiple host migration
is fine.
For resolving localhost migration issue, we can listen by
'-incoming tcp:localhost:$port' and migrate by 'migrate
-d tcp:localhost:$port'. Or listen by '-incoming tcp:0:$port'
and migrate by 'migrate -d tcp:0:$port'
This patch uses second resolution.
