I'm using quantum-dhcp-agent 1:2013.1.3-0ubuntu1~cloud0 and its unable to start due to bad stdout when running dnsmasq --version. Which version of dnsmasq should I install that is compatible with quantum/neutron?

The code checks that the dnsmasq version is >=2.59. But you are getting "UNKNOWN" for the version instead of a number. How did you install dnsmasq? What does 'dpkg -l dnsmasq\*' show?

I use chef to automate + using stackforge's cookbook. They compile dnsmasq from source and its unable to put an actual version during compile (see answer below)

Figured it out;

I use opscode chef to automate deployment and using The cookbook compiles its own dnsmasq from source due to a bug. Ended up manually installing it myself and cookbook skips it.

Here's the line from the attribute + the link to the bug filed:

# On ubuntu precise, we build dnsmasq from source to fetch a more recent
# version of dnsmasq since a backport is not available. For any other
# platform, dnsmasq will be installed as a package
# See
default["openstack"]["network"]["dhcp"]["dnsmasq_url"] = ""

# The name of the file we will fetch
default["openstack"]["network"]["dhcp"]["dnsmasq_filename"] = "v2.65.tar.gz"

# The checksum of the remote file we fetched
default["openstack"]["network"]["dhcp"]["dnsmasq_checksum"] = "f6cab8c64cb612089174f50927a05e2b"

# The package architecture that will be built which should match the
# archecture of the server this cookbook will run on which will be
# amd64 or i386
default["openstack"]["network"]["dhcp"]["dnsmasq_architecture"] = "amd64"

# The debian package version that the above tarball will produce
default["openstack"]["network"]["dhcp"]["dnsmasq_dpkgversion"] = "2.65-1"
