Thank you for the comments.
 The failure occurred with 3.10.0-2.10-generic as well for me. Please see the log that's attached in comment #11, and that occurred on my local raring machine. I can reproduce this issue on my local machine once every 4-5 attempts. As given in the description, the issue occurs more often when there are more VMs running. Therefore the frequency is very high in our server which is a precise 12.04.01 machine using 3.2.0-40-generic.

I am not sure if we have any special dnsmasq configuration in the lab. I'll check and confirm it with our systems engineers. But on my local machine (raring amd64 desktop) there is no specific configurations.

Since the issue is more often when there are more VMs installations in one host, it would be easier to reproduce by running 'sudo -u utah -i run_utah_tests.py -i /path/to/saucy-server-amd64.iso -p lp:ubuntu-test-cases/server/preseeds/mail-server.preseed lp:ubuntu-test-cases/server/runlists/mail-server.run -x /etc/utah/bridged-network-vm.xml' in parallel at the same time from a couple of terminal windows.

libvirt-bin that we are using is 0.9.8-2ubuntu17.8

The issue is not occurring during the install but on the first reboot after the installation.
