One of the most hotly contested issues debated on my training courses is whether you should or should not virtualize vCenter. Some folks are convinced that it should remain physicalized, citing somewhat out of date recommendations to this affect back in VMWorld 2005. Well, there’s nothing like keeping your best practice policies up-to-date is there. As for me, I’ve always been strong advocate of virtualizing vCenter – and I often pretend I don’t know how to install Windows to physical box to remind people that VMware’s management server benefits from virtualization just like any other workload. However, it's not without caveats, not least an interesting feature of vSphere which now makes virtualizing vCenter trickier than it was in previous releases. It does seem to be the case that people have an ideological opinion on this before they have even thought of the technical merits.
