For some unknown reason the original implementation of the <forwarder> element only took advantage of part of the functionality in the dnsmasq feature it exposes - it allowed specifying the ip address of a DNS server which *all* DNS requests would be forwarded to, like this: <forwarder addr='192.168.123.25'/> This is a frontend for dnsmasq's "server" option, which also allows you to specify a domain that must be matched in order for a request to be forwarded to a particular server. This patch adds support for specifying the domain. For example: <forwarder domain='example.com' addr='192.168.1.1'/> <forwarder domain='www.example.com'/> <forwarder domain='travesty.org' addr='10.0.0.1'/> would forward requests for bob.example.com, ftp.example.com and joe.corp.example.com all to the DNS server at 192.168.1.1, but would forward requests for travesty.org and www.travesty.org to 10.0.0.1. And due to the second line, requests for www.example.com, and odd.www.example.com would be resolved by the libvirt network's own DNS server (i.e. thery wouldn't be immediately forwarded) even though they also match 'example.com' - the match is given to the entry with the longest matching domain. DNS requests not matching any of the entries would be resolved by the libvirt network's own DNS server. Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1331796
