Package: libvirt-bin Version: 0.9.12-5 Severity: wishlist Tags: pca.it-virtualization
Hi there!
While debugging #689221, I experienced such a bug, which is actually the
counterpart of #504605, which I still think it deserves a better
solution ;-)

=====
Even after having read #504605, I fail to see why dnsmasq started by
libvirt should need --bind-interfaces at all, but I am probably missing
something. dnsmasq_2.63 introduced a new bind option, I would say
better than the above:
--bind-dynamic
Enable a network mode which is a hybrid between
--bind-interfaces and the default. Dnsmasq binds the
address of individual interfaces, allowing multiple
dnsmasq instances, but if new interfaces or addresses
appear, it automatically listens on those (subject to
any access-control configuration). This makes
dynamically created interfaces work in the same way as
the default. Implementing this option requires
non-standard networking APIs and it is only available
under Linux. On other platforms it falls-back to
--bind-interfaces mode.
Thx, bye,
