Re: [libvirt-users] Changing dnsmasq DNS settings for virtual machines

There was a bug in libvirt for quite awhile that caused locally-unresolved requests for hostnames in the domain given by the network's <domain name='xyzzy'/> element to be dropped rather than forwarded. Is that possibly the cause of your problems? Alternately, since 1.1.3 you can tell dnsmasq to forward to a specific address rather than the one listed in /etc/resolv.conf with the <forwarder> subelement of the <dns> element in the network definition, e.g.: <dns> <forwarder addr='1.2.3.4'/> </dns> This is documented here: http://www.libvirt.org/formatnetwork.html#elementsAddress There was a bug in libvirt for quite awhile that caused locally-unresolved requests for hostnames in the domain given by the network's <domain name='xyzzy'/> element to be dropped rather than forwarded. Is that possibly the cause of your problems? You do that with the <host> subelement of the <dns> element. An example is at the same link as above.
