Re: [libvirt] [PATCH] Don't use AI_ADDRCONFIG when binding to wildcard addresses

https://bugzilla.redhat.com/show_bug.cgi?id=1098659 With parallel boot, network addresses might not yet be assigned [1], but binding to wildcard addresses should work. For non-wildcard addresses, ADDRCONFIG is still used. Document this in libvirtd.conf. [1] http://www.freedesktop.org/wiki/Software/systemd/NetworkTarget/ ---
