The VM estate that I manage is large: there are more than 20 different clusters and over 300 hosts of varying ages and hardware levels – as a consequence there are various different versions of ESX and ESXi running. Upgrading the hosts is somewhat akin to painting the Forth Bridge, a never-ending task. So keeping the thousands of VMs at the correct hardware and VMtools versions can be a bit of a losing battle.
