• receiving an allocation of run-time memory for the virtual guest, the allocation of run-time memory comprising a portion of run-time memory of the host computing system;
• and
• setting, by the virtual guest, at least a portion of the allocation of run-time memory to be inaccessible by the virtual machine manager.

A method comprising:

• deploying a virtual guest security apparatus onto a host computing system, the virtual guest security apparatus capable of:
• initializing a virtual guest on the host computing system, the host computing system comprising a virtual machine manager, the virtual machine manager managing operation of the virtual guest, the virtual guest comprising a distinct operating environment executing in a virtual operation platform provided by the virtual machine manager;
• receiving an allocation of run-time memory for the virtual guest, the allocation of run-time memory comprising a portion of run-time memory of the host computing system;
