The only reason that I mention it is becuase there are a bunch of
VMWare pro folks out there that consider it a short coming of the
other platforms.
Frankly, arguments can be made all ways.
The hypervisor will slowly become a commodity driving the focus from
the hypervisor to other virtualization items and to the management
experience, which will become a more important differentiator (it is
currently a consideration).
And sooner or later that world will change as well - as standards come
into play that are currently still in flux.
