[Pkg-libvirt-maintainers] Bug#704803: libvirt-bin: Dnsmasq uses /etc/hosts from host which breaks on (at least) isolated networks

[Daniel Dickinson (sole proprieter)]

Package: libvirt-bin
Version: 0.9.12-11
Severity: normal

Because libvirt-bin dnsmasq instances uses hostnames and ip addresses from /etc/hosts on the host DNS requests for a hostname specified for a libvirt address (e.g. on an isolated network) also return the results from /etc/hosts.  Particularly on an isolated network (where /etc/hosts ips are usually not valid) this breaks virtual hosts, or the host requesting an address from the libvirt-bin dnsmasq intending to only get a VM's address on an isolated network.

/etc/hosts should not be used by libvirt-bin's dnsmasq instances IMO.
