Hyper-V Server 2008 R2 Embedded

Hyper-V Server 2008 R2Configuratie en beheer

Installatie• Hardware Requirements

– Hardware-assisted Virtualization support (Intel-VT, AMD-V)– Data Execution Prevention enabled

• Additional hardware support for:– Virtual Machine Queues (VMQ)– Second Level Address Translation (SLAT)

• Extended Page Tables (EPT) – Intel• Nested Page Tables (NPT) – AMD

• Media– Bootable USB/DVD

• 10 to 15 minute install (~ 1,5 GB ISO)• WDS

Configuratie met SCONFIG

Sconfig ‘onder water’• Vbscript in %SystemRoot%\System32\%locale%

– C:\windows\system32\en-us– Roept objecten aan, WMI, tools

• Allow MMC Remote Management– Enables VDS (automatic and start)

• Enable Windows PowerShell– Stelt Execution Policy in– Installeert .Net Framework (enable feature)

• Enable Server Manager Remote Management– Installeert Server Manager PowerShell cmdlets

• Download and install updates– Voert separaat download script uit

• Failover Clustering Feature– Enable/Disable Failover Clustering

Overige command line tools• Network Shell

– Netsh• File System Utility

– Fsutil• Access Control Lists

– Icacls• Disk Partitioning

– Diskpart

iSCSI en MPIOMulti-path management

Enable MPIOocsetup MultipathIo

Command line (mpclaim.exe)GUI (mpiocpl.exe)

iSCSI initiatorCommand line (iscsicli.exe)GUI (iscsicpl.exe)

Additionele tools

• Core Configurator 2• Draait op de host

– Remote PS in de planning

• http://coreconfig.codeplex.com/

Specifiek: untrusted scenario• Untrusting domains, workgroups• Vereist erg veel configuratiewerk:

– Mirrored admin accounts– WMI security permissions (root\cimv2, root\virtualization)– Azman security permissions (InitialStore)– DCOM security permissions permissions– Diverse firewall rules

– Aanpassingen gelden zowel client als server side

• Oplossing: gebruik HVRemote.wsf– Configureert alle instellingen voor remote management in alle scenarios

High Availability• Failover Clustering• 16 nodes per cluster• Ondersteund maximum van 64 VM’s per node

• Aanbevelingen– Voorkom een ‘hollands cluster’

• 1 node voor failover, extra node voor onderhoud– Afhankelijk van cluster-grootte

– Netwerk adapters:• 1 NIC voor domain access en management• 1 NIC voor virtual machines• 1 NIC voor CSV / Live Migration (>= 1Gb)• 1 NIC voor iSCSI

Beheer op afstand…Enable remote management via SCONFIG, beheer via

Hyper-V manager in Windows Server 2008 R2Remote Server Administration Tools for Windows 7 (gratis)

Microsoft System Center Virtual Machine Manager 2008 R2PowerShell (ISE + Remoting)

Server Manager Remote• 2008 R2 maakt remote

management via ServerManager mogelijk

• Vereist “Enable ServerManager Remote Management”

• Vereist Windows Firewallinbound rules te worden enabled

Samenvatting Hyper-V Server 2008 R2

• Gratis• Gelijke eigenschappen als de Windows Enterprise-editie

– Gebaseerd op Core

• Kleine footprint, snel• Eenvoudig te installeren en beheren

Hyper-V Server 2008 R2• Microsoft.com/virtualization

– Startpunt voor virtualisatie

• Deploying Microsoft Hyper-V Server 2008 R2 on USB Flash Drive– Artikel op TechNet

• Create bootable USB drive for Hyper-V Server 2008 R2– Tool op code.msdn.microsoft.com
