Did you do an apt-get update here? If not, then you didn't get the
updated kernels.

Yeah that wouldn't be worth it.

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?
