I have been forced to familiarize myself very closely with VMware ESXi.
I came to the conclusion that ESX (i.e. the hypervisor itself) is the best operating system ever, simply because it is literally impossible to break. Any change to the system image will vanish upon reboot. If you want your change to survive a reboot you must package it into the system image manually (i.e. create a VIB file and load it into the system). And if you create a VIB which breaks the system you have an option to revert to the previous system image at the boot time. Oh, and did I mention that the system image and the data stores are kept completely separate? Actually, I have trouble imagining a situation which would leave me with a completely unbootable system. Plus, it boots off an USB stick, so you can just copy (image) the stick prior to changes for extra safety...
You can even compile Linux software to run on the ESX host itself (yay!) except that the proces is a bit arcane. The secret is to use a Linux distro from 2007 because VMware for some reason refuses to upgrade the Linux image they are using...
Oh, and do you know that you can virtualize ESX on ESX?
