Where to start and where to end?

Some that I can think of:

- Unsupported hardware --> check HCL at http://www.vmware.com/resources/compatibility/search.php

- Compatibility issues --> http://www.vmware.com/pdf/vsphere4/r40/vsp_compatibility_matrix.pdf

- Storage issues --> choose the correct storage for your needs: shared storage vs. local storage, LUN/disk sizes, controllers, write cache

- hosts over or under utilized --> make an assessment of what you want to virtualize (CPU, IOPS, RAM, disk space, ...)

- Overcomitment of CPUs (e.g. 4-8 vCPUs for a VM) --> use less vCPUs

- Snapshot issues --> http://kb.vmware.com/kb/1015180

- Networking setup --> http://www.vmware.com/files/pdf/virtual_networking_concepts.pdf

- VMware Tools --> always install VMware tools in the VMs

- Backup --> Snapshots are no backups! Make sure you have a backup strategy.

- Keep yourself up to date --> e.g. VMware KBs at http://blogs.vmware.com/kbdigest/

DJ,

Have a look at the VMware Support Microsite - they keep an updated list of the 10 most popular KB articles:

This isn't necessarily a 10 top issue list but last year Petri did a 10 top steps for improving VM performance.
