Abstract
A computer system is disclosed that includes a host operating system and a virtual hypervisor that operates under management of the host operating system to control operations of virtual machines operating under management of the virtual hypervisor. The virtual hypervisor provides an interface between the virtual machines and the host operating system. A signing component generates digital signatures which identify owners of the virtual machines and associates the digital signatures with the virtual machines. A signature validation component determines the owners of the virtual machines using the digital signatures and responsive to occurrence of defined events. Related methods and computer program products for operating computer systems are also disclosed.
