Abstract
A method of establishing trusted operability between virtualized states of a Network Functions Virtualization (NFV) system providing a network service and operating in a virtual computing environment is disclosed. The method comprises receiving, by a physical server, a request to execute a trusted process, wherein the physical server comprises a processor with at least one core processing unit. The method further comprises assigning, by a trusted hypervisor, the execution of the trusted process to a first virtual server on a first core processing unit, dedicating physical portions of cache, memory, and disk storage to the first core processing unit; and executing the trusted process. The method further comprises receiving, by the physical server, a request to execute an untrusted process and assigning, by the trusted hypervisor, the execution of the untrusted process to a second virtual server on a second core processing unit, and restricting access to the trusted process.
