You can use the tcpdump logs in wireshark, or you can yum install
wireshark and use that interactively right on the bridge.

Yes, the problem is actually in the Xen API for 3.2, they added an
option in the API, but didn't provide a default value if the client
doesn't provide one, so it bombs.

I have a fix for it. I could send the whole src.rpm, but it is too
much baggage for the list, so I have thrown in the 2 patches to
be put in the SOURCE directory and an updated xen.spec file.

Rebuild the packages, update them then virt-manager and virt-install
should work.
