Did you do an apt-get update here?

Ok, let's see if using just the bridge without kvm can reproduce the problem. If you can, please try the following: 1. Get a usable ns_exec: git clone git://git.sr71.net/~hallyn/cr_tests.git cd cr_tests git checkout ns_exec make ns_exec cp ns_exec /bin/ 2. Create a veth tunnel sudo ip link add type veth 3. Open two root terminals to configure a network namespace for our test terminal 1: ip link add type veth terminal 2: /bin/ns_exec -cmn /bin/bash echo $$ # call this $pid henceforth terminal 1: ifconfig veth0 0.0.0.0 up brctl addif virbr0 veth0 ip link set veth1 netns $pid # use pid from above terminal 2: ifconfig veth1 up dhclient veth1 Now, on either the host or on an external host, do nc -4 -k -l 9999 And from terminal 2 start dumping data while [ 1 ]; do echo ab | nc ipaddr 999 sleep 0.5s done where ipaddr is the host or external host's ip address. Does that eventually lock up too? -- Broken networking in kvm guests https://bugs.launchpad.net/bugs/616064 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
