Abstract

According to one example, a method performed by a physical computing system includes, with a hypervisor, detecting that a guest system running on a virtual machine has executed a halt instruction for a virtual processor of the virtual machine. The method further includes, with a physical processor, switching from a context of the virtual machine to a context of the hypervisor. The method further includes re-entering the context of the virtual machine in response to determining that there are no tasks pending for processes outside the context of the virtual machine, the processes being for execution by the physical processor.
