Using a VMWare system to compensate for a lack of multicore capability is
definitely an ugly hack.  Please don't accept this in bid responses as a
reasonable way of getting around this limitation. Modern operating systems
(yes Windows, but also Unix/Linux) are starting to assume multicore in
their design. Using single core mode on these systems severely limits their
capability, and introduces a risk that a misbehaving process can eat the
entire CPU, crashing your system. You end up having to spend more money on
redundant and special use systems and licenses (like dedicated Pi or eDNA
systems) to avoid overtaxing the CPU.
Why pay for a dual or quad core system, and then let someone eliminate 1/2
to 3/4 of that capability?  I'd ask for $5000 of the $10000 back in support
credits.
