Free Windows Sysinternals Tool Captures Online operating systems Can run from GUI or Command Line Runs on XPSP2, Server2003 SP1 and

higher (Including x64 systems)

Virtual Hard Disks

VHD is the common Virtualization format Supported on Virtual PC, Virtual Server and

Hyper-V OS/Applications/Data in a single file

VHD Types

Dynamically Expanding Fixed Size Differencing

VHD Sources

Build them from scratch Microsoft VHD Test Drive Program Migrate VHD’s from VPC or VS Import them from other Hyper-V Servers Capture a physical machine

Migrate A VHD from Virtual PC or Virtual Server VHD format is portable Remove Virtual Machine Additions first! Create a New Virtual Machine Add an existing Virtual Hard Disk

“DO NOT IMPORT!”

Import/Export VHD’s

Use the Export and Import tools in Hyper-V In order to import an .exp must be present No moving VHD’s after import

Snapshots

Point in time snapshot of a VHD Stored as AVHD file type Can be structured into hierarchical

trees Can be imported and exported

DemoWorking with Snapshots

Virtualization as a SQL Server consolidation Strategy

Compelling features SQL running in a VM gives immediate isolation capabilities at different levels

Hardware isolation facilitates easy migration and HA Resource isolation enables predictable performance

Increased hardware utilization with multiple VMs Multi Server Management cost savings Convenient unit of SQL Application life cycle management Identify opportunities for Data platform standardization

Summary

Hyper-V is a great base for building a testing environment!

TechNet Plus is a great source for Operating Systems and Applications

VHD format is very flexible Disk2vhd makes captures free and easy Snapshots make moving from point in time

to point in time very easy
