On quantal, I can't get such a VM to run without it automatically loading vhost_net. The following kvm command
sudo kvm -hda x.img -netdev tap,ifname=tap0,id=hostnet0,vhost=on -device virtio-net- pci,netdev=hostnet0,id=net0,mac=52:54:00:d8:33:46,bus=pci.0,addr=0x3 -vnc :1 causes vhost_net to get loaded. (The same command doesn't quite work in precise) I'll leave the testcase (with nc) running for a few hours on quantal in any case. Then I'll replace my quantal install with a precise one, and try again to reproduce there. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to bridge-utils in Ubuntu. https://bugs.launchpad.net/bugs/997978 Title: KVM images lose connectivity with bridged network To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bridge-utils/+bug/997978/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
