A guest disk may be setup through the assistance of a restore environment. A restore environment may be bundled with partitioning software, and the restore environment may be a small, lightweight Linux&#x2122; environment that is operating-system agnostic. The restore environment allows any operating system image file to be deployed on the guest disk. The guest disk may be created through the use of virtualization software and a guest operating system.

Technique for deploying operating systems in a virtualized environment

A computer system comprises a plurality of processing modules that can be configured into different partitions within the computer system, and a main memory. Each partition operates under the control of a separate operating system. At least one shared memory window is defined within the main memory to which multiple partitions have shared access, and each partition may also be assigned an exclusive memory window. Program code executing on different partitions enables those partitions to communicate with each other through the shared memory window. Means are also provided for mapping the physical address space of the processors in each partition to the respective exclusive memory windows assigned to each partition, so that the exclusive memory windows assigned to each partition appear to the respective operating systems executing on those partitions as if they all start at the same base address.
