Abstract

See full text

In an approach to sharing memory between a first guest and a second guest both running on a data processing system, one or more computer processors provide a virtual device to a first guest for proxying memory accesses between the first guest and a second guest, where the first guest is associated with the second guest, and where the first guest is running a first operating system and the second guest is running a second operating system. The one or more computer processors send one or more device related functions to the second guest, wherein the virtual device enables sharing memory between the first guest and the second guest.
