Please test the packages from the attachment in comment #6. (You can also get them from ppa:serge-hallyn/virt) If these do indeed fix the issue for you, then I'll issue a SRU to get this fix into maverick.
I've marked the main bug 'fix released' since natty has the fix from upstream (and since this is a prerequisite for SRU). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/668043 Title: libvirt default network doesn't start, iptables errors, bad rules -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
