@Serge i actually experienced the problem on my laptop but never tried the proposed packages. After removing dnsmasq package i had manually added, the problem disappeared.
Would you like me to reinstall dnsmasq again and try the proposed packages? -- 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
