A method for implementing a shared memory buffer includes at an apparatus comprising a processor and a physical memory, running a host environment with a host virtual memory. The method further includes running a guest environment with a guest virtual memory, performing, by the host environment, an allocation of a frame buffer in the physical memory, and mapping the allocated frame buffer into the host virtual memory. Additionally, the method includes passing a handle of the allocated frame buffer to the guest environment and performing a mapping of the allocated frame buffer into the guest virtual memory, the mapping based on the handle of the allocated frame buffer.
