I don't see how it will help a user. VMware exports a PCI device, and
this device will be available only when running under a VMware
hypervisor. If a particular device is available the OS will use the
corresponding driver.
Please note these drivers will be used by the guest operating system,
which is running virtualized.
I don't get what kind of control the administrator has on this ? can you
please elaborate.
