After a quick search in VMware Communities I found that there is a need to update information about Veeam Stencils, a completely free tool for drawing diagrams in Microsoft Visio.
Veeam Stencils has been recently updated. Now this set can be used in Microsoft Visio 2003, 2007 and 2010 and contains a number of new icons for your VMware and Hyper-V virtual environments. As usual, inside of Veeam Stencils you'll find stencils for VMs with different statuses, VMware and Hyper-V hosts, datacenters, storages and so on.
You can download the new version of Veeam Stencils here: http://www.veeam.com/vmware-esx-stencils.html
Please let me know if any questions will appear or you will need any assistance.
