Perhaps I should explain that everywhere I've worked that uses VMware, the
VMware
admins are almost always current or former Windows admins. Naturally that's
because
there are hundreds-to-thousands of desktops being driven out of VMware, and
many now
are Horizon so they don't even have full, real hardware, so they're
VMware-dependent.

As a result of these "facts on the ground", linux VMs do not have the
"administrator mindshare"
that Windows VMs have with the VMware system admins (current/former Windows
admins).
Not even if they are fundamental to the business.

As I mentioned, it's more sociology than computer science.
