That is a totally bogus assumption. You will typically have the host
platform (Vmware in this case) move much much slower than the guests.
This is strictly for new installations. And I frankly don't
see why Linux needs to get white listed workarounds when the
Hypervisor couldn't as well be fixed. We have the bizarre
situation here where a HV vendor tries to add workarounds
to Linux instead of fixing it on their products.
... just like every other hardware vendor.
