> How much do you think VMWare is going to impact OS research?
Anyone building a new x86 OS today would be a fool
not to start by doing it on top of VMware. It's just
so much easier than working on real boxes. The only
reason I can think of not to use VMware is if you were
trying to build something like a microkernel where you
care about every little architecture trick and the
associated speed benefits. (VMware implements the tricks,
they just might not have the usual costs.)
It's still nice to run on the bare hardware, though.
Compiling is an order of magnitude faster that way,
mainly because there are so many context switches to
kfs and back. (Using a network file server might
help here quite a bit; I haven't measured that.)

So much for tact.

How much do you think VMWare is going to impact OS research?
I look at the work that's done on the BSDs and Linux because the driver
base is there, but it seems that for people doing lower-level work,
there's a lot to be said for using VMWare if your research or interests
lie somewhere other than driver development, or if nothing else as a
proof-of-concept before diving into driver hell but without supporting
decaying hardware along the way.
Does this seem like a plausible future?
