Hypervisor virtual processor execution with extra-hypervisor scheduling
Moving scheduling of processor time for virtual processors (VPs) out of a virtualization hypervisor. A host operating system schedules VP (virtual processor) processor time.

Of note is the security separation between VP scheduling and VP context switching. The hypervisor manages VP context switching in kernel mode while VP scheduling is performed in user mode.

Technologies described herein reduce the size of a software application. In some embodiments, the size of one or more resource files of an application are reduced.
