We're running qemu-kvm 1.0+noroms-0ubuntu14.13 on a 12.04.4 LTS with KVM based 12.04.4 LTS virtual machines , and have observed this problem. We have been using the regular software bridges on many machines, and have only noticed the problem on one of our newest servers.

Using virtio devices we get the discussed lockups.

Using e1000 we get no lockups, but this is a much lower performing interface and thus we have performance issues. We have NFS and other traffic between VMs and the host, so need more than the GigE that we have to external hosts.

I note above that this bug was considered fixed by qemu-kvm - 1.0+noroms-0ubuntu14.3, but this appears to not be the case.
