8.2.1 Data Transfer

The per-(virtual)-device ring between the guest and the block backend supports two messages:

Read data from the specified block device. The front end identifies the device and location to read from and attaches pages for the data to be copied to (typically via DMA from the device). The backend acknowledges completed read requests as they finish.

Write data to the specified block device. This functions essentially as READ, except that the data moves to the device instead of from it.
