Memory management in a nested virtualization environment

A system for managing memory in a nested virtualization environment, the system comprising:

• a physical memory from which a first guest memory is allocated to a first virtual machine (VM) implemented for a first software,
• a logic unit for maintaining a first data structure to translate one or more memory addresses in the first guest memory to corresponding memory addresses in the physical memory;
• a logic unit for maintaining a second data structure to translate one or more memory addresses in a second guest memory to corresponding memory addresses in the physical memory;
• wherein the first software comprises a logic unit for implementing a second VM for a second software such that the second guest memory is allocated to the second software;
• and
• wherein the first software further comprises a logic unit for maintaining a third data structure to translate one or more memory addresses in the second guest memory to corresponding memory addresses in the first guest memory.

A computer program product comprising a computer readable medium having logic code stored thereon, wherein the logic code when executed on a computer causes the computer to:

• implement a first virtual machine (VM) for a first software such that a first guest memory is allocated to the first software;
• maintain a first data structure to translate one or more memory addresses in the first guest memory to corresponding memory addresses in a physical memory;
• maintain a second data structure to translate one or more memory addresses in a second guest memory to corresponding memory addresses in the physical memory;
• wherein the first software implements a second VM for a second software such that the second guest memory is allocated to the second software;
• and
• wherein the first software maintains a third data structure to translate one or more memory addresses in the second guest memory to corresponding memory addresses in the first guest memory.
