Is it? How easy is it to run VM-in-VM with VMware? (That's a serious
question; I have never even looked at it myself. Work has never
required it, and, like all closed-source software, it's simply not
under consideration for my home use. Someday I want to learn enough of
the x86 hypervisor hardware facilities to build a hypervisor of my own,
but so far opportunity and inclination have not coincided for that.)
Yes, you can run VMware within VMware within VMware. People do it
for lab testing to see how a network of VMware hosts will interact
with each other. There's a performance hit, of course, but it works.
Don't forget to add the complication (a.k.a. feature) that each of
those VMware can have their own virtual networks and virtual switches
within. And what you do within the virtual machines within each layer
is your own business; run whatever emulators within emulators that
you like.
Also keep in mind that Windows 7 Pro gives you a free downloadable
Virtual PC and a license to a Windows XP Mode, and Windows 8 Pro gives
you Hyper-V. Virtualization is at the fingertips of desktop users.
Functionality that once required a complicated install on its own
PC is now distributed as a several-gig virtual machine that includes
its own operating system.
To me, this is the way that emulators should be distributed for
learning purposes. I've seen so many emulators that need all sorts
of hand-tweaking of the emulator's configuration that requires
foreknowledge of the typical configurations of the emulated system
in question. The newbie doesn't know two layers of that. Give 'em
a ready-to-go typical experience in an easy download that drops into
VMware Player or Hyper-V.
