O'Reilly's first book on virtualization uses our popular Cookbook format to give you ideas about administrative tasks you might not have thought you could do, or could be doing more efficiently. In preparation for the main annual VMware conference, VMworld (August 31--September 3 in San Francisco), we've put a couple recipes online: Ethernet Traffic Shaping and Monitoring CPU Usage.

Thanks to George Reese, I learned about the bruhaha over an Open Cloud Manifesto. Let's put the debate in the context of some basic and perennial issues about openness and standards.
