[virtio-dev] [PATCH] Define the DEVICE ID of Virtio Cpu balloon device as 47

[-- Attachment #1: Type: text/plain, Size: 772 bytes --]

The virtio CPU balloon device is a primitive device for managing guest
CPU capacity: the device asks for certain CPU cores to be online,
offlined or throttled, and the driver performs the requested operation.
This allows the guest to adapt to changes in allowance of underlying CPU
capacity.

The Virtio CPU balloon device is a primitive device for managing guest
CPU capacity: the device asks for certain CPU cores to be online,
offline or throttled, and the driver performs the requested operation.
This allows the guest to adapt to changes in allowance of underlying
CPU capacity.

I'm holding off voting for now until the status of the OASIS
infrastructure migration is clear (sigh).

Is there ETA for the migration?

Bests,

Well, I wish I knew...
