Data center backends use more and more RDMA or RoCE devices and more and more software runs in virtualized environment. There is a need for a standard to enable RDMA/RoCE on Virtual Machines. Virtio is the optimal solution since is the de-facto para-virtualizaton technology and also because the Virtio specification allows Hardware Vendors to support Virtio protocol natively in order to achieve

Hello, Sometimes the backend of PVFB knows that it doesn''t need permanent refresh, when the window is minimized for instance (no refresh at all), or the administration tools know that the window is thumnailed, and so a slow refresh rate is fine. Also, some users may want to tune the refresh rate according to the smoothness they would like, balanced with the CPU time that requires.
