Suppose vmware decides to switch between running Linux and its virtualised Windows OS. Can it do this during an interrupt - if so what ensures that vmware isnt switched to after we have done APM idle calls and slowed the CPU right down ?
If so then I suspect vmware should be issuing APM cpu busy calls itself
