And VMware ESX -- the robust production server host -- only takes about 3-5% overhead, not the higher numbers quoted earlier.
There are "hosted" versions of VMware (Workstation and GSX) which run under Windows or Linux and do have higher overhead, but they're not for a production server consolidation project.
And VMware can do things that VM can't... Imagine taking a running active server and dynamically moving it to another physical processor -- never missing a beat.
And while VMware can't overcommit memory in the same ways that VM can, VMware running several similar servers (Windows or Linux) will cause the servers to "share" identical pages of memory -- similar in result to VM's shared segments.
But VMware -- just like Linux on a zSeries -- needs to be properly sized and positioned to be successful. VMware is a bit less forgiving when you overcommit processor, memory of other components.
