Don't know if you still need an API Changelog entry, included it here just in case. --------------------------------------------------------------- API Changelog entry: PV framebuffer dynamic resolution facility: Guest may send XENFB_TYPE_RESIZE if feature-resize = 1 in xenstore of the backend VNC server. VNC server code sets feature-resize if it can handle the resize request. VM kernel module parameter array, xenfb.video, is used to set the amount of frame buffer memory in MB allocated and the initial width and height. IE: extra="xenfb.video=3,1024,768 " New xenstore virtual machine specific VNC attributes: videoram: Sets the maximum allowable frame buffer allocation size in MB. Protects against a hostile frontend trying to run dom0 out of memory. Not set by defualt IE: vfb=['type=vnc,vncunused=1,videoram=3'] --------------------------------------------------------------- Signed-off-by: Pat Campbell
