This has been asked in previous topics and the official answer from Cisco is that it is not supported.
I'm in a delemma at the moment. Have been waiting for 6 months now to have Ciscoworks installed on a standalone server. New directions and policy have now dictated that Ciscoworks be installed on VMWare. We have frustratingly lobbied for months now that Cisco does not support it and neither would our maintenance partner.
The result is now that in the next few days i will be handed a new "virtual" server with my Ciscoworks installed on it...unless I can substantiate reasons why Cisco does not support it. Any help from the Cisco engineers on this would greatly be appreciated.
