No idea, the guide acts as a very nice general installation manual.
Combine that with the presence of multiple emulators (QEMU, Bochs, 
VMware) as well as some actual installations, and you get inflated 
numbers indeed.

True. Lots of people will likely virtualize additional functionality, be 
that generated by Linux, Windows, ReactOS or another operating system.

It appears that VirtualBox developers are taking the easy way out, 
creating virtual machines that work properly for specific operating 
systems instead of being a proper complete virtualisation product. In 
other words, the VM is incomplete, not acting like real hardware would. 
VMware (Workstation, Fusion and ESXi), Bochs and QEMU appear to do a 
better job of complete emulation, with VMware (and to a lesser degree 
QEMU) adding optimalisation for specific operating systems ('virt-io' 
devices and drivers included..)

What you mention unfortunately is reality indeed. Instead of creating a 
proper product with full functionality and afterwards improving, only 
just enough functionality is provided to get popular operating systems 
going. In some ironic way, this resembles real hardware :)

Unlikely. However any and every bug with regard to machine emulation 
should be fixed to get rid of imperfection. Afterwards all that users 
can complain about then is performance rather than functionality.

I know Michael Devore added a feature to FreeDOS-EMM386 (and thus also 
present in JEMM/JEMMEX) to exclude a certain UMB memory region if 
running in VMware. It was done at my request, as otherwise the VM would 
reboot or crash. Not everything can be worked around for in drivers or 
operating systems, if the system environment is flawed.
