Oracle introduce Oracle Virtual Assembly Builder for Virtual Appliances
“Oracle Virtual Assembly Builder is a new product designed to help organizations quickly and easily deploy multi-tier enterprise applications in Virtualized Environments. It also enables administrators to quickly configure and provision these applications.”
This is sound very interesting, reconfiguration of Applications is main challenge in Virtual Appliances.

Mainstream HW for Cloud: Dell present Cloud oriented solutions
Dell present new server lines optimized for low-cost Cloud solutions:
New servers are part of Dell strategy Open Solutions For The Virtual Era
Similar 2U 4 dual socket boards systems are already shipped by SuperMicro one of the main Tear-1 OEM suppliers.
AMD Opteron 2000 – SuperMicro A+ Server 2021TM-BTRF
Intel Xeon 5500/5600 SuperServer 6026TT-BTRF
As Intel will make available new Energy Efficient Xeon 7500(6500) processors Nehalem line, we will see more solutions like these,
as Intel announced new line will have initially 11 members, from which 3x will have TPW 95W and 4x 105W.
100W is known limit for such 2U 4 dual socket boards solutions.

Part 12: Glassfish V3 Pet Catalog sample DEMO in VM Template – Clean and Convert
OpenSolaris 200906 JeOS Prototype was designed as PURE CLI enviroment providing main building stone for creation of Virtual Appliances or VM Templates
In this example I will DEMOnstrate creation of Evaluation type Virtual Appliance / VM Template which will leveradge OpenSolaris 200906 JeOS prototype and just in Dec/09 released Glassfish v3, Java EE 6 and Netbeans 6.8 with simple Java EE 6 demo. This entry is part of Virtual Appliances & OVF workshop.
