Current workaround: use 3.11 kernel in firewallvm, instead of the now-default 3.12 due to netback changes.

Actually kernel 3.12 behavior is correct - when VM signals qemu to unplug the emulated devices, stubdomain shutdown the device and prepare for reconnect. In earlier kernels it was just broken (but that reconnect never happend, so nobody cared).

The proper fix is to disable this reconnect thing in stubdomain:

BTW it worth to check if that kernel change fixed #722
