The issue is that vdev_netvsc tries to setup failsafe on all netvsc devices it sees, and it determines which ones are used by OS based on somewhat fragile OS probes with netlink. I would recommend getting rid of vdev_netvsc, or make the the auto scanning there something that has to be forced by devargs. But that really is up to the netvsc maintainers.
