Btw, what is that intel thing everyone is talking about? And why

It's not a thing it's Zhu Lingshan :) intel is just one of the vendors
that implemented vdpa support and so Zhu Lingshan from intel is working
on vdpa and has also proposed virtio spec extensions for migration.
intel's driver is called ifcvf. vdpa composes all this stuff that is
added to vfio in userspace, so it's a different approach.
Well, so let's call it virtio live migration instead of intel.
And please work all together in the virtio committee that you have
one way of communication between controlling and controlled functions.
If one extension does it one way and the other a different way that's
just creating a giant mess.
I hope so, Jason Wang has proposed a solution to cooperate, but sadly
rejected...
