My system monitor shows Qemu using physical memory if it's available. Just as
any application will.
The bog is at the cpu level, I'm 0% idle whenever Qemu is running even the
smallest task.
Even ram must pass through the cpu, which is why changes in ram have little/no
effect on performance.
At least that's what I'm seeing... I should add that I know nothing. lol
