Abstract

A system, method and computer program product for implementing a thin hypervisor. The thin hypervisor does not have any association with a VM. The thin hypervisor serves as a wrapper over hardware capabilities of a processor. The processor has privileged low-level capabilities EPT VTX, AMD V and the ARM has virtualization technology. In order to use processor hardware capabilities and receiving root privileges, the system operates in a “super user” mode. The VM operates in a VM environment with kernel privileges in a user mode. A super user space is created in a safe mode. A user space application (or a process) is created. A user space virtualization framework library is used. These entities are separated by a user space and a kernel space. A thin hypervisor is implemented in the user space.
