Good: - Very, very stable - The only real vmware software designed for server apps - Performance VM QoS for disk, cpu, network, etc - Easily run 30-40 VM's on a strong box w/ good mem - Deals with lots of NIC's assigned to different vm's - Per VM User Access Policies - Very nice realtime performance reporting Bad: - Dont use for apps that really need performance of dedicated boxes - Not cheap, especially if get all the management add ons. - Setting up some of the networking is more complicated than it needs to be. - Not very good w/ linux 2.6 kernel support yet (read, dont do it) - I don't find the rollback, and cloning functionality as useful as others. In fact, I've seen some vm's be corrupted if you select the "append" mode for disk writes, which creates a redo log that can get lost if the server hardware crashes.
