Abstract
A method of handling an event occurring in a nested virtualization computing environment is provided, wherein N hypervisors are executed nestedly, with a first hypervisor running at level zero (L0) directly over a host machine, and other hypervisors nestedly running at levels L1 to Ln, respectively. The method comprises trapping an event generated by software running at level Ln; determining a hypervisor x at level Lx designated for handling the trapped event; and wherein the hypervisor x emulates features needed for performing the trapped event for the software running at the level Ln.
