Usecase
-------
Virtio-net standby allows easy migration while using a passed-through fast
networking device by falling back to a virtio-net device for the duration of
the migration. It is like a simple version of a bond, the difference is that it
requires no configuration in the guest. When a guest is live-migrated to
another host QEMU will unplug the primary device via the PCIe based hotplug
handler and traffic will go through the virtio-net device. On the target
system the primary device will be automatically plugged back and the
net_failover module registers it again as the primary device.

The primary device can be hotplugged or be part of the startup configuration

-device virtio-net-pci,netdev=hostnet1,id=net1,mac=52:54:00:6f:55:cc, \

With the parameter failover=on the VIRTIO_NET_F_STANDBY feature will be enabled.
-device virtio-net-pci,netdev=hostnet1,id=net1,mac=52:54:00:6f:55:cc,bus=root2,failover=on

failover_pair_id references the id of the virtio-net standby device. This
is only for pairing the devices within QEMU. The guest kernel module
net_failover will match devices with identical MAC addresses.

Hotplug

Both primary and standby device can be hotplugged via the QEMU monitor. Note
that if the virtio-net device is plugged first a warning will be issued that it
couldn't find the primary device.
Both primary and standby device can be hotplugged via the QEMU
monitor. Note that if the virtio-net device is plugged first a warning

Migration
---------
A new migration state wait-unplug was added for this feature. If failover primary
devices are present in the configuration, migration will go into this state.
It will wait until the device unplug is completed in the guest and then move into
active state. On the target system the primary devices will be automatically hotplugged
when the feature bit was negotiated for the virtio-net standby device.
