NOTIFY_ON_EMPTY is in the MAY be offered category. I'm still wondering about the old legacy bits. Transitional devices not offering them is easiest to implement from the host side, but I'm wondering if all legacy devices will be able to function with missing bits? Is breaking some legacy drivers OK?

What it is: vhost net is a character device that can be used to reduce the number of system calls involved in virtio networking. Existing virtio net code is used in the guest without modification. There's similarity with vringfd, with some differences and reduced scope - uses eventfd for signalling - structures can be moved around in memory at any time (good for migration) - support memory
