Patent ID: 8352940

Claim:
A computer implemented method for providing an interface between a virtual cluster proxy and a virtual I/O server on a logical partitioned platform, wherein the virtual I/O server is configured to support virtual real memory, the method comprising: receiving a command at a virtual cluster proxy, wherein the virtual cluster proxy provides virtualization management for the logical partitioned platform; identifying, by the virtual cluster proxy, whether the command is a virtual real memory command or a virtualization command, wherein the command is the virtual real memory command or the virtualization command if the command invokes processes on the virtual I/O server; responsive to determining that the command is the virtual real memory command or the virtualization command, marking, by the virtual cluster proxy, the command with a virtualization marker, wherein the virtualization marker indicates that the command is the virtual real memory command or the virtualization command, forwarding, by the virtual cluster proxy, the command to a logical partitioned platform; intercepting the command at a virtual memory manager to identify whether the command has been marked with the virtualization marker; responsive to identifying that the command has been marked with the virtualization marker, re-routing the command to the virtual I/O server, wherein the virtual I/O server facilitates the sharing of physical I/O resources between logical partitions on the logical partitioned platform and is configured to support virtual real memory.
