Enhanced virtualization protection technology may require the use of bounce buffers for I/O. While support for this was built into the virtio core, virtio-ccw wasn't changed accordingly. Some background on technology (not part of this series) and the terminology used. * Protected Virtualization (PV): Protected Virtualization guarantees, that non-shared memory of a guest that operates in PV
