Looking Glass is an open source application that allows the use of a KVM (Kernel-based Virtual Machine) configured for VGA PCI Pass-through without an attached physical monitor, keyboard or mouse.
Looking Glass Memory Protocol (LGMP)
LGMP is an Inter-VM Shared Memory Device (IVHSMEM) based memory sharing protocol for the KVM Frame Relay use-case (sharing of MMIO memory for use by GPU drivers between host and guest).
Xen Support
It may be possible to port the Looking Glass Memory Protocol to Xen by substituting the use of the Grant Table memory sharing primitive in place of the IVSHMEM memory sharing primitive.
Telescope
The LGMP protocol may also be extended over a high bandwidth network using the Telescope Looking Glass Proxy.
