Session Roadmap
What you need to get started Hardware and software Working with Virtual Machines Optimizations
Some Vocabulary
Virtual machine—a “completely isolated guest operating system installation within a normal host operating system” Host—the physical machine providing hardware services Guest—a virtual machine running on a host
Different Types of Virtualization
Operating System Application Presentation Device
Microsoft Virtualization Technologies
Hyper-V Boot To VHD App-V Remote Desktop Services Virtual PC Virtual Server Windows Virtual PC
Hyper-V
Microsoft’s enterprise class hypervisor that relies upon processor provided hardware virtualization Requires 64-bit version of Windows host OS First made available in Windows Server 2008 Updated in Windows Server 2008 R2 and SP1 Windows Server 2012 provides the magical 3rd release Windows 8 Professional and Enterprise support Hyper-V on the client
Hardware
Processor RAM Hard disk Video Networking
Processor
Processor Specific Virtualization Intel VT AMD-V What about that extra stuff in my BIOS? Sockets, Cores, and Hyper-threading SLAT required for virtualization on Windows 8 Client
demo
Checking for Support
Set up your host
Configure Hyper-V Use Add/Remote Programs on Client Server Manager, Add Role
demo
BCDEDIT
Set up your guests
MSDN and Technet are your friends Product Activation Sysprep Keeping things up to date
RAM
Generally more is better Optimize for use case Dynamic memory in Hyper-V Do more with less
demo
Dynamic Memory
Physical Storage
DAS SSD Hybrid Mechanical Network-based iSCSI on the cheap Production SANs
Virtual Storage
Virtual Hard Disk Two formats VHD Limited to 2 TB in size VHDX—new for Windows 8 and Windows Server 2012 Better resiliency Up to 64 TB in size Can be fixed or dynamically expanding in size Support differencing disks and snapshots
demo
Hard Disk Performance
Boot to VHD
Device Virtualization Presents a “native” hard drive to your host computer Can use with or without a native install BCDEDIT is your friend So are BCDBOOT and DISKPART System Configuration Tool (MSCONFIG.EXE) does some things if you need a GUI Boot to VHD supports VHD and VHDX (only Win8/2012) Can be Dynamic, Fixed, or Diff Drive EXPANDS to full size if a Dynamic or Differencing VHD(x)
demo
Boot to VHD
Video
Video Cards in general don’t have a huge impact You’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 2012 Requires Remote Desktop Services Virtualization Host Additional Licensing Requirement Requires a compatible video card
demo
RemoteFX
Tips
VM Creation Sysprep is your friend Diff drives are another great feature Snapshots Provide your VMs until UNDO and REDO Limited to 50 per VM Eat disk space Capture both data and configuration changes
Deleting Virtual Machines
Deleting the Virtual Machine from the console does not remove it’s files Deleting 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 strategies Delete the snapshots from the bottom up first Apply 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 careful Watch out for drives > 2 TB pre-Windows 8 Things that don’t work or work well in virtual machines Windows Phone Tools Profilers Programs that need direct access to hardware
thumbdrive.vhd
Using SCSI adapters and VHDs makes it easy to hot move your data to & from VMs Great when you don’t have network connectivity Great to bring data to each new VM Installs Source files Whatever
Optimize your Dynamic VHDs
Compact is built-in to the Console Tools Only does tail end clean up Use SDELETE from Sysinternals to zero out free space
demo
Tips
Automation
Hyper-V exposes a WMI interface on all versions SCVMM 2008 and later offer PowerShell Cmdlets Hyper-V on Windows 8 also provides in box PowerShell support via CmdLets
demo
Hyper-V and PowerShell
Good bye
Thank you for coming! Virtualization is for everyone Live long and prosper
