KVMGFX
======
Looking Glass
=============
Purpose
-------
@ -57,6 +57,8 @@ The shared memory segment is intialized by the guest with a strcture that
describes the format of the frame and the current mouse coordinates. Frame data
is appended to the buffer after this header.
We have decided upon he name "KVM FrameRelay", or "KVMFR" for this technology.
### Video Transfer
The guest runs a program that uses the ivshmem device as a direct transfer
