Description of problem:

Version-Release number of selected component (if applicable):

libvirt-1.1.3.5-2.fc20.x86_64

Unfortunately I was not able to test this with upstream
libvirt since it seems the ./run script is broken.  My program
is unable to connect to the session libvirtd socket.

How reproducible:

With 1.1.3.5-2, 100% reproducible.

Steps to Reproduce:
1. Run virt-v2v under valgrind.
2. Supply the libvirt test XML from here:

https://github.com/libguestfs/libguestfs/blob/master/v2v/test-v2v-networks-and-bridges.xml.in

3. Something about the bridges & networks in this XML causes a
memory leak in the test driver, as shown above.
