PDI 2009 Lance Baatz and Jason Huitt ACNS

 Introduction  Hyper-V Architecture  Installing Hyper-V and creating Virtual Machines using Hyper-V Manager  System Center Virtual Machine Manager  Our (ACNS’s) Setup  Questions To get the most out of this session, please feel free to jump in with your questions at any time.

 Hyper-V is Microsoft’s hypervisor ◦ Type 1 “bare-metal” as opposed to Type 2 “hosted”  Included as a beta in RTM Server 2008 ◦ Officially released on June 26, 2008 as an update ◦ Free “Hyper-V Server 2008” released Oct  Hyper-V is a “Role” available for enabling ◦ 64-bit versions of 2008 Enterprise and Datacenter ◦ Requires x64-based Intel VT or AMD-V processors ◦ DEP and Virtualization must be enabled in BIOS “It provides simple partitioning functionality and is responsible for maintaining strong isolation between partitions. It has an inherently secure architecture with minimal attack surface, as it does not contain any third-party device drivers.” - Microsoft

 Windows Server 2008 x64 ◦ Datacenter: Unlimited Windows-based Guest VMs ◦ Enterprise: Maximum of four Windows-based Guest VMs running at any one time ◦ CALs are required regardless of server OS version  Server 2008 Server Core ◦ Hyper-V is supported, however…  Initial Setup and Configuration  Troubleshooting  Lack of a GUI for network configuration is unpleasant ◦ Our recommendation: avoid Server Core for Hyper-V until you are very familiar with each moving part

 Obtain as much horsepower as possible  RAM….lots of it ◦ You cannot commit more memory to VMs than physically exists in the host machine  2 NICs ◦ Dedicated NIC for host ◦ Dedicated NIC for Hyper-V  Storage ◦ Depends on purpose of the system

 Windows NT Architecture  Virtual Server 2005  Server 2008 without Hyper-V  Server 2008 with Hyper-V  VMWare Comparison  Hardware Presented to Guest OS  Hyper-V Networking

 Dedicated underlying OS  Requires custom device drivers  Potential advantages: ◦ Provides support for virtualizing USB devices ◦ Supports memory overcommit  Potential disadvantages: ◦ Supports memory overcommit ◦ Much more expensive than Hyper-V for production system ◦ Moves away from “Microsoft across the board…”

 Chipset ◦ Intel 440BX  CPU ◦ Based on the host CPU, selections made in System Center Virtual Machine Manager  BIOS ◦ AMI BIOS  Video ◦ S3 Trio 32/64 with 4MB of video memory  Memory ◦ As much as you allocate – cannot allocate more than physically present on host PC  Input Devices ◦ PS/2 Mouse and Keyboard  Floppy Drives ◦ Up to two 1.44MB 3.5" floppy drives  IDE Controllers ◦ Two channels, each of which supports up to two devices each (up to four IDE total devices)  SCSI Controllers ◦ Up to four Adaptec 2940 SCSI Controllers (each supports up to 7 devices; 28 devices total)  Network Interfaces ◦ DEC/Intel /100Mb network interface cards

 Easy in practice, can be difficult to conceptualize  In other words, take it slow and methodically & document!  Best practice: dedicate a NIC for management  Hyper-V supports Q – VLAN Tagging  Allows support for multiple IP subnets on a single wire  Can eliminate the need for a NIC on every network  Three types of Hyper-V networks  External – Provides direct access to physical network  Internal – Isolated within host, between VMs and host  Private – Isolated within host, no access from host OS

 Legacy Network Adapter (Emulated) ◦ Basic NIC presented to an “unenlightened” guest ◦ Supports PXE boot for Remote Installation Services ◦ Support for this NIC in WinPE by default ◦ Basic OS support going back to Windows 95  “Enhanced” Network Adapter ◦ Requires Integration Components for OS to use ◦ No PXE boot ◦ Much faster performance ◦ Driver included in Server 2008 / Vista by default

 Create and Manage Virtual Machines ◦ Add disks, networks, etc. ◦ Set automatic start and stop options ◦ Snapshots  Create Virtual Hard Disks ◦ Fixed vs Dynamically Expanding ◦ Fixed disks must be created prior to a virtual machine being created  Manage Virtual Networks  Connect to Virtual Machines

 Install “Integration Components” aka “Integration Services” ◦ Allows for better user experience when connecting to VMs and “enlightens” the Guest Virtual Machine ◦ Integration Components are already installed in Vista and Server 2008 ◦ Integration Components exist for XP, Server 2003, and several flavors of Linux  Build “library” of VHDs ◦ Create Virtual Machine, install software, sysprep, shutdown, and copy VHD to “library”  Demonstration…

 Capable of managing Hyper-V and newer VMWare deployments  P2V (Physical to Virtual) conversions  Catalogs Virtual Machine deployments across servers and simplifies the process of moving VMs from one host to another  Provides a management interface for virtualization resources - VHDs, hardware configs, etc…  Integrates nicely with Operations Manager  Including performance and resource optimization monitoring

 Heads Ups: ◦ Install on a dedicated server ◦ Install Hyper-V role on VMM server ◦ Requires SQL Server ◦ Still need to use Hyper-V Manager for some things  Creating VHDs  Installing Integration Services  Demonstration…

 Three Production Hyper-V Hosts ◦ Two stand alone host servers ◦ One 3-node cluster  Requires shared storage, currently using iSCSI  Virtualized Servers/Services ◦ Single-purpose servers ◦ Test environments ◦ No plans to virtualize Exchange or production SQL Server services

 Currently being done at the “guest”  Future Options: ◦ Data Protection Manager ◦ EqualLogic tools
