What does the Adaptive Hypervisor check box actually do for v 4.0 Parallels. By the way, great job development did on this release, I can run it along side virtualbox and vmware now and no one crashes.
Enable the Adaptive Hypervisor option to automatically allocate the host computer CPU resources between the virtual machine and Mac OS X applications depending on what application you are working with at the moment. If you are working in a virtual machine application, the CPU resources will be allocated to the virtual machine, if you switch to the host OS application - the CPU resources are relocated to Mac OS X, and vice versa.
Which sort of makes me wonder: why would one NOT want this option enabled? Why make it an option at all, rather than just a feature?
Well, I for one do not want the feature enabled by default. I really do not know what goes on behind the scenes to make this work. Messing around with scheduling priorities is not something I want some application doing if this is how it is achieved. If it isn't using scheduling or renice, then I want to know more.
I turned it off because I want my windows os to actually do work while in the background, and with the AHV on, it lollygags around when you aren't watching it. I could see it as being useful under some circumstances, however.
I have tried fixed memory and variable memory. The guest OS is more robust under fixed memory. Under variable, there is a drag on speed. WRT HyperVisor, I have tried it "on" and "off" and have not seen a difference. YMMV
