[libvirt] [PATCH] Bind to ip_addr support.

[Stefan de Konink]

Hi,


Mainly because I think Daniel always gives good feedback and comments,
plus I don't want to be a troll on this list, I decided the time had come
to spend some minutes to hack up a patch :)

It has been tested:

tcp        0      0 192.168.0.5:16509       *:*                     LISTEN

vs

tcp        0      0 *:16509                 *:*                     LISTEN


Only lefts me:

By making a contribution to this project, I, Stefan de Konink, certify
that:

(a) The contribution was created in whole or in part by me and I have the

(c) The contribution was provided directly to me by some other person who
