Depends what you're truing to do.  a small DOS VM shouldn't take a lot of RAM.

This would be the bigger issue.  You are definitely going to get better
performance running DOS on x86 hardware than on another processor, because the
amount of software emulation required is much less.

There's also another issue.  DOSemu is much "lighter" than loading Qemu and
then DOS/FreeDOS, so the startup time for the door would be somewhat faster
oo.
