Between WS6 and WS6.5 the vmci device was changed in a backwards-incompatible
way. That is, the vmci device present in WS6.5 (and in any hardware version 7
VMs) is a different device than the experimental vmci device that shipped in
WS6 (hardware version 6 VMs).
As such, the vmci driver in the open-vm-tools will only drive the VMCI device
present in hardware version 7. So if you want to use it, you'll need to get
your hands on WS6.5, which I believe is in either beta or RC at the moment. If
you want to stay with WS6, the vmci driver in the open-vm-tools won't be of any
use to you and you'll need to use the vmci module source that shipped with the
WS6 Tools.
