Anyone who has installed VMware's ESXi4 hypervisor (if you haven't then get an idea of what you are missing with my article on how to setup your own ESXi4 server will be aware that the options for maintenance at the server itself are somewhat limited. In fact its just a one page menu: For setting up your ESXi4 server you don't even need to go that far in fact, since you can just point your vSphere Client at the IP assigned to the server by DHCP and do everything afterwards from there.

Killing in the name of

Since vSphere has been introduced more and more of my customers are migrating to ESXi. It makes sense as the thin hypervisor is the way of the future according to VMware.
