For an unfortunately large number, yes.

Our servers dealing with financial exchange data live on the bleeding
edge of capacity and can't afford the overhead of virtualization. So
we end up replacing the backend servers wholesale every few years,
re-purposing the older generation for less demanding tasks. But,
within the realm of hardware with compatible drivers there's not a
whole lot of difference in the effort to copy a VM image or a hardware
image with clonezilla or a similar approach.  I agree that VMware is
great where it works, though.
