Partitioning a hypervisor into virtual hypervisors

Abstract:

In an example, a computer system includes a hardware platform and a hypervisor executing on the hardware platform. The hypervisor includes a kernel and a plurality of user-space instances within a user-space above the kernel. Each user-space instance is isolated from each other user-space instance through namespaces. Each user-space instance includes resources confined by hierarchical resource groups. The computer system includes a plurality of virtual hypervisors, where each virtual hypervisor executes in a respective user-space instance of the plurality of user-space instances.
