I'm not sure it really matters whether QEMU is emulating a machine in software or using a hardware assist. The point is, it's pretending to be a full machine either way and it's faithfully simulating the processor and other hardware. Software might be able to tell that it's on hardware or software based on timing or other side effects, but QEMU is not picking and choosing what parts of the environment it chooses to support.
DOSBox and DOS emulators are not virtual machines. Nobody uses the terminology that way. -Mike On Wed, Mar 8, 2023 at 6:04 PM Steve Nickolas <usots...@buric.co> wrote: > On Wed, 8 Mar 2023, Michael Brutman wrote: > > > Sorry, we have a terminology issue here.
