Module Overview

• Configuring Hyper-V Servers

• Configuring Hyper-V Storage

• Configuring Hyper-V Networking

• Configuring Hyper-V Virtual Machines

What's New in Hyper-V 3.0?

• Virtual machine replication

• Hyper-V PowerShell support

• QoS bandwidth management

• NUMA support

• Memory improvements

• Resource Metering

• Virtual Fibre Channel

• Live migration without shared storage

• New virtual hard disk format

• SMB 3.0 storage

• Network virtualization

Prerequisites for Installing Hyper-V

• Server hardware must support:

– Hardware assisted virtualization

– Data execution prevention

– SLAT

• Hardware must be adequate to support the needs

of virtual machines with respect to: – Memory

– Disk I/O

– Processing capability

– Network throughput (typically multiple NICs)

Hyper-V Integration Services

Series of services you can use with supported VM operating systems

Best Practices for Configuring Hyper-V Hosts

• Provision the Hyper-V host with adequate

hardware resources

• Deploy virtual machines on separate disks

• Do not colocate other Windows Server 2012 roles

on the Hyper-V host

• Manage Hyper-V remotely

• Run Hyper-V by using the Server Core

configuration

• Use Resource Metering and Best Practices

Virtual Hard Disks in Hyper-V 3.0

Windows Server 2012 introduces the new VHDX

format for virtual hard disks, which:

• Supports bigger disks

• Is less likely to lose data during unexpected

outages

• Supports better alignment when deployed to a

large sector disk

• Allows larger block size for dynamic and

differencing disks, which provides better

performance

Disk Types

Type of disk Description

Fixed All of the hard disk space is allocated

during the creation process

Dynamic The disk itself only uses the amount of

space that needs to be allocated and

grows as necessary

Pass Through Virtual machines access a physical disk

drive rather than use a virtual hard disk

Differencing

The amount of hard disk space

consumed by virtual hard disks is

reduced at the cost of disk

performance

Converting Disks

• You can perform the following maintenance

operations on virtual hard disks: – Convert the disk from fixed to dynamic

– Convert the disk from dynamic to fixed

– Convert a virtual hard disk in VHD format to VHDX

– Convert a virtual hard disk in VHDX format to VHD

DEMO: Managing Virtual Hard Disks in Hyper-V

• In this demonstration, you will see two different methods

of creating a differencing disk

Location Considerations of Virtual Hard Disks

When planning the location of virtual hard disks, ensure

the following:

• Virtual hard disk files are stored on disks that can be

accessed quickly from the Hyper-V host

• Virtual hard disk files are stored on a volume that is

configured for redundancy

• Virtual hard disk files are stored on high-performance

storage

• Virtual hard disk files configured for growth should be

placed on volumes with adequate space

Storage on SMB 3 File Shares

Hyper-V 3.0 can store the following on SMB 3 file shares:

• Configuration files

• Snapshot files

• Virtual hard disk files (in VHD or VHDX format)

SMB 3 is available in Windows Server 2012 only, and not in

earlier Windows Server versions

Snapshot Management in Hyper-V

• Snapshots provide administrators with the ability

to make a replica of a virtual machine at a

particular point in time

• Snapshots do not replace backups – Snapshots written as avhd files, which merge back in the

previous snapshot when the snapshot is deleted

– Snapshot of running virtual machine includes the

contents of memory

Fibre Channel Support in Hyper-V

The Fibre Channel adapter:

• Allows a virtual machine to directly connect to a

Fibre Channel SAN

• Requires that the Hyper-V host has a Fibre

Channel HBA

• Requires that the Fibre Channel HBA driver

supports virtual Fibre Channel

Best Practices for Configuring Virtual Networks

• Use NIC teaming on the Hyper-V host to ensure

connectivity to virtual machines if an adapter fails

• Enable bandwidth management to ensure that no

single virtual machine is able to monopolize the

network interface

• Use network adapters that support a Virtual

Machine Queue

• Use network virtualization when you have to

ensure that virtual machines keep their original IP

addresses after migrating to a new host

Overview of Virtual Machine Settings

Grouped into two general areas…

How Dynamic Memory Works in Hyper-V

• Use dynamic memory

settings to configure

Hyper-V so the VM is

allocated as much as it

needs.

• In Windows Server 2012,

you can modify dynamic

memory settings while

the VM is running

Importing, Exporting, and Moving Virtual Machines in Hyper-V

• When importing virtual machines in Hyper-V:

– You can get access to a more detailed diagnostic

information

– You can import copied virtual machine files

• When exporting virtual machines, two options: – Export snapshot for point in time export

– Export virtual machine to export all snapshots

• When moving virtual machines: – You can relocate virtual-machine files while the virtual

machine is online

– You can perform a live migration

Best Practices for Configuring Virtual Machines

• Use dynamic memory unless an application does

not support it

• Avoid using differencing disks

• Configure multiple synthetic network adapters

• Store each virtual machine’s files on a separate

volume
