Description
VMMs can maintain separate execution domains for each executing guest VM by assigning each guest VM a separate address space. Each VMM guest VM has a distinct address space so that communication between guest VMs is performed in a manner controlled through the security functions of the VMM, and one guest VM cannot modify the executing code of another guest VM. This capability is available in most commercial VMMs that employ virtualization processor technologies.
