There are numerous resources available online for virtualizing Oracle 10g as stand-alone databases. If I were doing this in this way, I would still go with the free version of ESXi. This gives you the best overall control for resource assignment between the databases while using the smallest amount of RAM overhead for the hypervisor. It also does some things with RAM that will make things more efficient. And as I mentioned earlier, you have positive control over the network interfaces such that they can be pooled or dedicated as needed for performance and security issues. Check the following URL for some good technical information for virtualizing Oracle on ESXi, and includes specifics on 10g: http://www.vmware.com/solutions/partners/alliances/oracle-database-whitepapers.html What's nice here is that several of the things covered are also transferable to other hypervisors if you understand how each of them handles resource management, disk storage, and networking. Also keep in mind that you will still need to license the box itself for Oracle. That part doesn't change. Hope that helps.
