[Qemu-devel] [PATCH] iotests: 147: Don't test inet6 if not available

[Fam Zheng]

This is the case in our docker tests, as we use --net=none there. Skip
this method.

FWIW, in test-io-channel-socket.c we call getaddrinfo() and also check
bind() succeeds (use port==0 to let it select a free port to test bind
on), before assuming IPv6 is working.

Well it then sounds like we should check bind(port=NBD_PORT). But if we do that,
it looks like a slightly bigger topic, for example a previous run not cleanup?

Let's leave it for now.

I thought you might want to respond to Dan's comment. If you don't plan
to make the change he suggests, let me know and I'll queue the patch as
it is.

This check is enough for me and I think it's good to go.

That's fine with me - i didn't intend my comments to be a blocker. In
general getaddrinfo should only return IPv6 addrs, if IPv6 is actually
usable.
