I've created a VMware specific icon set with the 2009 icons provided to the public here: http://viops.vmware.com/home/blogs/strategy/2009/02/23/build-your-own-high-quality-vmware-diagrams-and-presentations
Included are the following icons (up, warning, down & unknown):
BladeChassis
Building
Cluster
Desktop
ESXhost
NIC
Router
Storage
Switch
ThinClient
Virtual Machine
Let me know if you like it or need any of the other icons.
Thanks.
