Red Hat and Microsoft make nice on virtualization. Vodafone’s new Android handset. Esmertec acquires Purple Labs and becomes Myriad Group AG. Krugle acquired by Aragon Consulting Group. Serena boasts of 1 million Projity downloads. And more.

Virtual agreement
The big news of the week was undoubtedly Red Hat’s virtualization interoperability agreement with Microsoft. The official announcement is here, Microsoft’s take is here and Red Hat’s is here. Just in case you thought the companies had settled their differences entirely, the FAQ is also worth a read: “Is this a joint agreement between Red Hat and Microsoft? It’s not a joint agreement. Red Hat has signed an agreement to join Microsoft’s Server Virtualization Validation Program, while Microsoft has joined Red Hat’s Virtualization Certification Program.”
