           DISCLAIMER:
           ===========
           There is a FFL/FFDD offloader running on this machine
           via qemu.

           service qemu-offloader status

           to be cleaned up:
           - let procd gracefully kill the vm on stop/shutdown
           - remove network hook /usr/lib/offloader_vm_net_up
