This is already fixed in upstream (in the manner the reporter suggests); see commit d175caad25a4e80800d5e7e7d8c9d920a88b78e1 from git://git.et.redhat.com/libvirt.git, attached.
I've applied that patch to libvirt0 0.4.0-2ubuntu8. It applies cleanly except for a reject on the changelog, and it does fix the problem. (I ran across this trying to set up a virtual gfs2 cluster for testing; it failed because cluster nodes rejected traffic that (due to thbe unnecessary masquerading) appeared to come from the host instead of the other (guest) cluster nodes.) ** Attachment added: "Tweak masquering rules to only capture traffic leaving the virtual network" http://launchpadlibrarian.net/16140534/0001-Tweak-masquering-rules-to-only-capture-traffic-leavi.patch ** Changed in: libvirt (Ubuntu) Status: New => Confirmed -- overzealous masquerading affects vm to vm traffic https://bugs.launchpad.net/bugs/227837 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
