Virtualization Provides Flexibility

Session Roadmap

What you need to get startedHardware and software

Working with Virtual MachinesOptimizations

Some Vocabulary

Virtual machine—a “completely isolated guest operating system installation within a normal host operating system”Host—the physical machine providing hardware servicesGuest—a virtual machine running on a host

Different Types of Virtualization

Microsoft Virtualization Technologies

Hyper-V

Microsoft’s enterprise class hypervisor that relies upon processor provided hardware virtualizationRequires 64-bit version of Windows host OS

First made available in Windows Server 2008Updated in Windows Server 2008 R2 and SP1Windows Server 2012 provides the magical 3rd release

Windows 8 Professional and Enterprise support Hyper-V on the client

Checking for Support

Generally more is betterOptimize for use caseDynamic memory in Hyper-V

Do more with less

Virtual Storage

Virtual Hard DiskTwo formats

VHDLimited to 2 TB in size

VHDX—new for Windows 8 and Windows Server 2012Better resiliencyUp to 64 TB in size

Can be fixed or dynamically expanding in sizeSupport differencing disks and snapshots

Hard Disk Performance

Boot to VHD

Device VirtualizationPresents a “native” hard drive to your host computerCan use with or without a native installBCDEDIT is your friend

So are BCDBOOT and DISKPARTSystem Configuration Tool (MSCONFIG.EXE) does some things if you need a GUIBoot to VHD supports VHD and VHDX (only Win8/2012)

Can be Dynamic, Fixed, or DiffDrive EXPANDS to full size if a Dynamic or Differencing VHD(x)

Boot to VHD

Video

Video Cards in general don’t have a huge impactYou’re stuck with the emulated video card

RemoteFX however brings a rich experience to your virtual machines by utilizing your video card’s GPU

Requires Server 2008 R2 SP1 or Server 2012Requires Remote Desktop Services Virtualization Host

Additional Licensing Requirement

Requires a compatible video card

Tips

VM CreationSysprep is your friendDiff drives are another great feature

SnapshotsProvide your VMs until UNDO and REDOLimited to 50 per VMEat disk spaceCapture both data and configuration changes

Deleting Virtual Machines

Deleting the Virtual Machine from the console does not remove it’s filesDeleting a Virtual Machine with Snapshots will cause the snapshot tree to merge with the parent VHD

Can take a LONG TIME to complete if what you really want is to just get the thing removed

Two strategiesDelete the snapshots from the bottom up firstApply the root snapshot and then delete the tree (my fav)

Tips

When using Boot to VHD make sure you use fixed size drives unless you’re really going to be carefulWatch out for drives > 2 TB pre-Windows 8Things that don’t work or work well in virtual machines

Windows Phone ToolsProfilersPrograms that need direct access to hardware

thumbdrive.vhd

Using SCSI adapters and VHDs makes it easy to hot move your data to & from VMsGreat when you don’t have network connectivityGreat to bring data to each new VM

InstallsSource filesWhatever

Optimize your Dynamic VHDs

Compact is built-in to the Console ToolsOnly does tail end clean up

Use SDELETE from Sysinternals to zero out free space

Tips

Automation

Hyper-V exposes a WMI interface on all versionsSCVMM 2008 and later offer PowerShell CmdletsHyper-V on Windows 8 also provides in box PowerShell support via CmdLets
