Take A Test Drive
VMware, Citrix, and Virtual Iron all have full-featured demos available to try before you buy. If time allows, it may be worth the effort to build test clusters for your two top hosting candidates.

Live migration is a critical element of VM cluster management; however, you'll be able to save a lot of money if your organization can tolerate brief production outages to shuffle a VM from host to host. Likewise, assess your appetite for high-availability capabilities; high availability comes at an additional licensing premium.

Finally, a warning: The VM tools in this Rolling Review made it ludicrously easy to create a virtual server. Too easy.
