Second, I have it directly from folks who worked on
Hyper-V that it is
neither based on Unix/Linux, nor strongly influenced by either VMWare
or Xen. It was an entirely in-house project at MSFT that probably
includes more DNA strands from Windows than Unix et al. Some of the
stories about clashes with Cutler to change the Windows startup
sequence to accommodate Hyper-V are interesting (short version:
Cutler, in typical fashion, didn't want to and early versions of
Hyper-V basically booted under windows, then "took over" the running
machine so that Windows resumed, but suddenly in a VM where it had not
been before).
That sounds like what Compaq's CEMM (a.k.a. EMM386) did with MS-DOS.
