Virtual cluster proxy to virtual I/O server manager interface

摘要

An interface is provided between a virtual cluster proxy and a virtual I/O server on a logical partitioned platform. The virtual I/O server is configured to support virtual real memory. A command is received from a virtual cluster proxy. The virtual cluster proxy identifies whether the command is a virtual real memory command or a virtualization command. Virtual real memory commands and virtualization commands are marked by the virtual cluster proxy with a virtualization marker. The virtualization marker indicates that the command is a virtual real memory command or a virtualization command. The command is then forwarded to a logical partitioned platform. A virtual memory manager intercepts the command and identifies whether the command has been marked with the virtualization marker. If the command is marked with the virtualization marker, the virtual memory manager reroutes the command to the virtual I/O server.
