I had a similar problem (Gutsy/AMD64, 2.6.22-14-generic, kvm 1:16-1ubuntu2), in that tap0 wasn't visible (ifconfig -a) on my host, and kvm reported "can't add tap0 to bridge eth1: Operation not supported" when starting.
However, after my host finished booting and everything network related had finished initializing, tap0 had appeared, and I can configure them both to communicate without issue. -- kvm-ifup fails to bring up tap0 in feisty https://bugs.launchpad.net/bugs/125302 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
