[RFC PATCH v3 0/3] Enable virtio_net to act as a backup for a passthru device
...on by
- assigning the same MAC address to both VF and virtio interfaces
- setting a BACKUP feature bit on virtio that enables virtio to
transparently take
? over the VFs datapath.
- only enable one datapath at anytime so that packets don't get looped back
- during live migration enable virtio datapth, unplug vf on the source
and replug
? vf on the destination.
The VM is not expected and doesn't have any control of setting the MAC
address
or bringing up/down the links.
This is the model that is currently supported with netvsc driver on Azure.
