Agenda

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. 1 2008

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

What is Hyper-V?

“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

Versions and Licensing

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

Hardware Recommendations

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

A Shallow Dive into Hyper-V’s(Virtual) Physics

Windows NT Architecture

Virtual Server 2005

I/O in Virtual Server 2005

Server 2008 with Hyper-V

I/O in an “Enlightened” Guest OS

I/O in an “Unenlightened” Guest OS

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…”

To be fair, a look at VMWare…

VMWare Architecture

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 21140 10/100Mb network interface cards

What Hardware is visible to the Hyper-V Guest OS?

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 802.11Q – 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

Networking with Hyper-V

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

Types of Adapters

Hyper-V in Practice

Enable Hyper-V Role from Server Manager

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

Hyper-V Manager

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…

Hyper-V Manager

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

Systems Center Virtual Machine Manager 2008

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…

Systems Center Virtual Machine Manager 2008

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

ACNS Deployment

Currently being done at the “guest” Future Options:

◦ Data Protection Manager ◦ EqualLogic tools

ACNS DeploymentHyper-V Backups
