I'm not sure what you're doing with the 64 servers but I think what Lan was saying is that with a robust OS, applications/services/servers are isolated from each other with memory management built into the OS. You can run 10 instances of apache with multiple instances of mysql without having to add another OS wrapper and virutalized hardware around it. But if you have 64 servers because you have 64 customers who are running their software on your server than yup, VMs make it much easier. The hardware abstraction is an interesting thought and some of the imaging tools and failover tools would seem to also make life easier for server farm farmers.
