The O/S doesn't really know what the hypervisor is doing with the
physical RAM, it can be "ballooned" away from the O/S or the hypervisor
can spot those identical pages in use by multiple VMs and make them all
refer to the same physical page (with CoW for any changes of course).
Only RAM. windows in idle mode shouldn't chew any CPU
And when suspended it doesn't chew any RAM either.
Damned sight faster to restore an open VM session that boot
windows...wait...coffee... twiddle thumbs....
Personally I'd sooner just swap a disk over or boot into a
Then you are barking mad.
VM allows you to run two systems in parallel concurrently with windows
having FULL access to the host file systems.
It allows you painless backup and restore of the virtual machine to as
many snapshots as you have disk space for.
It allows superfast booting of the windows WITHOUT shutting down the host.
It allows windows to be suspended in seconds to free up ram and CPU if
you need them, and resumed in seconds when you want it back.
The only downsides are that the hardware is NOT fully under windows
control and sometimes that means some hardware wont work the way it was
intended, and it means that the screen is a bit slower.
The only possible reason I could have for a real live native windows
would be to play games on.
Or if I had some obscure hardware that ONLY ran on native windows.
As it happens, I don't have either requirement.
