VMware is holding a pair of Virtualization Forums, one day mini-conference designed to bring together virtualization experts and clients from within a region of the United States.  There are two Forums happening in December:

• December 3, 2008: San Diego
• December 11, 2008: Boston

A customer of mine attending one last year in Atlanta and indicated it was an excellent networking and learning event.  If you happen to be in one of these two cities, look into attending the Virtualization Forum.
