I use VMWare Workstation and keep my virtual machines on a separate physical disk, not my boot drive. Does this mean that the VM's IO will be against that disk when it is running?

Yes. All I/O in these virtual machines will be redirected by VMWare to the file that contains the virtual machine's disk. If that file is on secondary disk, then naturally all I/O will happen against that disk.

Note that this does not mean that I/O on the primary disk will not be impacted at all. Some I/O impact is system-wide (e.g. bus traffic, associated CPU-time, etc.)

right, just what I meant, in a clearer manner – Sathya Oct 13 '11 at 15:54

A bulk of them will hit the disk dedicated to the VM, but your primary disk will still be accessed especially for swap access & MFT updates
