[Bug 1126488] [NEW] libvirt instance of dnsmasq in raring fails to forward DNS requests

[Steve Langasek]

Public bug reported:

On a raring system, the dnsmasq instance spawned by libvirt is not
forwarding DNS requests to the upstream resolver.  dnsmasq is run as:
/usr/sbin/dnsmasq --conf-file=/var/lib/libvirt/dnsmasq/default.conf

The contents of default.conf are:

##WARNING:  THIS IS AN AUTO-GENERATED FILE. CHANGES TO IT ARE LIKELY TO BE
##OVERWRITTEN AND LOST.  Changes to this configuration should be made using:
##    virsh net-edit default
## or other application using the libvirt API.
##
## dnsmasq conf file created by libvirt
strict-order
domain-needed
user=libvirt-dnsmasq
local=//
pid-file=/var/run/libvirt/network/default.pid
except-interface=lo
bind-dynamic
interface=virbr0
dhcp-range=192.168.122.2,192.168.122.254
dhcp-no-override
dhcp-leasefile=/var/lib/libvirt/dnsmasq/default.leases
dhcp-lease-max=253
dhcp-hostsfile=/var/lib/libvirt/dnsmasq/default.hostsfile
addn-hosts=/var/lib/libvirt/dnsmasq/default.addnhosts

If I downgrade to dnsmasq-base 2.59-4 from quantal, comment out the
(unrecognized) 'bind-dynamic' option, and run with -z (for --bind-
interfaces), this dnsmasq instance then correctly forwards DNS queries.
