This protocol allows an in-guest agent to share clipboard data with dom0, so that it could be integrated with an emulated frame buffer, such as that exposed by qemu over VNC.

Status

Status: version 0.1 (early draft)

Overview

The protocol is intended to be used over a 'channel' with name: org.xenproject.guest.clipboard.0.1

The protocol is a subset of the VNC RFB protocol (http://www.realvnc.com/docs/rfbproto.pdf). Since the main expected use is to integrate with a qemu VNC frame buffer, RFB primitives should be readily available in the implementation.

We use only the following messages:

  • ProtocolVersion
  • SecurityVersion
  • ClientInit
  • ServerInit
  • ClientCutText
  • ServerCutText

Protocol

The backend acts as the RFB server, the guest acts as the RFB client.
