I think this was understood by the original poster, however don't be
so quick to discount Binary Translation. If you have an older
processor with the early versions of the VT extensions, they're
unlikely to get used as they perform worse than Binary Translation
on a platform that advanced it well (e.g. VMware). Even on the
newest processors, Binary Translation is used to handle some
scenarios as the VT extensions can't support them.<br>
<br>
The biggest gains from VT extensions have been in the context
switching arena and those gains are further increased on the vSphere
platform. If you keep the number of VMs and vCPUs minimal in
proportion to the number of physical CPUs, you shouldn't see too
much of a performance impact as the frequency of context switching
should minimized (still quite a lot, but normal) as a result. <br>
