While waiting for new hypervisor codename Viridian, Microsoft is pushing more on Virtual Server 2005, and published a set of 10 whitepaper to provide guidance in several integration scenarios:

• Microsoft Virtual Server 2005 R2 Service Pack 1 and Microsoft System Center Virtual Machine Manager
  The goal of this cookbook is to provide the steps and guidance necessary for you to successfully install and configure Virtual Server 2005 R2 SP1 and System Center Virtual Machine Manager. You may then create and manage virtual machines, and perform P2V migration.
• Backup and Recovery using Microsoft Virtual Server 2005 R2 Service Pack 1 and Acronis True Image 9.1 Enterprise Edition
  The goal of this cookbook is to guide you through installing Acronis server imaging solutions for workgroups and installing Microsoft Virtual Server 2005 R2 SP1. The cookbook covers creating a virtual machine (to serve as a standby for recovery) and restoring the contents of a server representing your production workload to the waiting virtual machine.
• Microsoft System Center Data Protection Manager 2007, Microsoft Virtual Server 2005 R2 Service Pack 1, and Microsoft System Center Virtual Machine Manager
  The scenario presented in this cookbook will take you through the steps necessary to install Virtual Server and SCVMM, and then convert a workload to a virtual machine. This cookbook also includes the steps necessary to install DPM and to back up a running virtual machine, as well as information about monitoring and reporting using DPM.
• Quick Migration with Virtual Server Host Clustering Windows Server 2003 Enterprise Edition & Microsoft Virtual Server 2005 R2 Service Pack 1
  This cookbook describes a simple configuration in which you use Virtual Server 2005 R2 to configure one guest operating system, and configure a server cluster that has two servers (nodes). With this configuration, you can migrate workloads easily from one node to the other.
• Mobile User Access of Applications. Terminal Server running on virtual machines using Microsoft Virtual Server 2005 R2 Service Pack 1
  In this cookbook we will install Terminal Server on a virtual machine and access the terminal server remotely. We will also show how to install Remote Desktop Web Connection and how to configure Windows® Firewall to allow remote clients to access the terminal server.
• Hosted Backup and Recovery Solutions for Service Providers using Data Protection Manager (DPM) and Virtual Server (VS)
  This cookbook will provide procedural, step-by-step guidance to an IT Generalist audience providing data backup and recovery to customers as a hosted solution using Virtual Server and System Center Data Protection Manager 2007.
• Simple Offsite Backup and Recovery of virtual machines using DPM and VS
  This cookbook will provide procedural, step-by-step guidance to an IT Generalist audience for backing up and restoring virtual machines running in an offsite location using Virtual Server and System Center Data Protection Manager 2007.
• Simple Onsite Backup and Recovery of virtual machines using DPM and VS
  This cookbook will provide procedural, step-by-step guidance to an IT Generalist audience for backing up and restoring running virtual machines using Virtual Server and System Center Data Protection Manager 2007.
• High Availability with VS and WS03R2 Enterprise Server Clustering
  This cookbook will provide procedural, step-by-step guidance to an IT Generalist audience for implementing high availability of server workloads using Windows Server 2003 Server Clustering and Virtual Server using Intel-based hardware.
• Application Isolation and Operation in BO Using VS
  This cookbook will provide procedural, step-by-step guidance to an IT Generalist audience for isolating and operating applications on separate virtual machines in branch offices using Microsoft Virtual Server 2005 R2 SP1, in an Intel-based hardware environment for regulatory compliance and improved legacy workload performance.
