  I'm looking for documentation about the Virtual Machine Manager that
  creates virtual machines in 386 enhanced mode.

The VMM is documented in the Device Driver Development Kit, which is available
from Microsoft for $500; there's an order form for it in the SDK.

You're "not supposed to" program virtual machines yourself; the DDK has
all this info so that virtual devices can handle requests from multiple
VMs.  You're supposed to use a protected-mode DOS extender (like the one
from Phar Lap) which in turn uses the DPMI (DOS Protected-Mode Interface)
spec to get Windows' cooperation in sharing protected-mode resources.
