What’s new in Windows Server Hyper-VBen Armstrong M227

What is this about?Giving you a detailed view of everything you can do with Hyper-V in Windows Server Technical Preview 3

It is not… A complete overview of everything that will be in the final release of Windows Server

Windows 10Many of these features are / will be available in Windows 10!

Hyper-V on Nano Server Minimum-footprint infrastructure OS and application OSNew Windows Serverinstallation option ‘Cloud-first’ refactoring• Essential infrastructure OS requirements • Essential application OS requirements

Server roles and features enabled• Hyper-V clustering, Storage• Next-gen application platform and run-time• Containers

Nano ServerServer Core

Minimal Server Interface

GUI Shell

Windows Server 2016

ContainersA new approach to build, ship, deploy, and instantiate applications

Physical

Virtual

}}

Apps traditionally tied to physical server

New apps required new servers for resource isolation

Higher consolidation ratios and better server utilization

High app compatibility

Physical/Virtual

}Benefits

Enable modern app patterns

Empower dev-ops collaboration

Agility with resource-control

containers

Package and run apps within

Making Cloud Great

Making Cloud Great• Security• Isolation• Availability• Operational Improvements• Scale

Security

Virtual Machine ProtectionTrust is the biggest blocker to cloud adoption• We want to allow customers to know that

their data is secure

Virtual TPM & Linux Secure Boot

Shielded Virtual Machines

Shielded Virtual Machines

Shielded Virtual MachinesShielded Virtual Machines can

only run in fabrics that are designated as owners of that virtual machine

Shielded Virtual Machines will need to be encrypted (by BitLocker or other means) in order to ensure that only the designated owners can run this virtual machine

You can convert a running virtual machine into a Shielded Virtual Machine

Secure Boot Support for LinuxProviding kernel code integrity protections for Linux guest operating systems.Works with:• Ubuntu 14.04 and later• SUSE Linux Enterprise Server 12

Secure Boot Support for LinuxPowerShell to enable this:

Set-VMFirmware "Ubuntu" -SecureBootTemplate MicrosoftUEFICertificateAuthority

Isolation

Distributed Storage QoSWindows Server 2012 R2:• Introduced the ability to limit maximum

IOPs for an individual virtual hard disk

Distributed Storage QoSWindows Server Technical Preview 3:Leveraging Scale Out File Server to allow you to:• Define IOPs reserves for important virtual

hard disks• Define a IOPs reserve and limit that is

shared by a group of virtual machines / virtual hard disks

Demo: Storage QoS

Host Resource ProtectionDynamically identify virtual machines that are not “playing well” and reduce their resource allocation

Virtual Machine Storage ResiliencyStorage fabric outage no longer means that virtual machines crash• Virtual machines pause and resume

automatically in response to storage fabric problems

Virtual Machine Cluster ResiliencyVMs continue to run even when a node falls out of cluster membershipResiliency to transient failuresRepeat offenders are “quarantined”

Shared VHDX

File Based StorageBlock Storage

Guest Clustering

Guest Clustering with commodity storage

Sharing VHDX files provides shared storage for Hyper-V Failover Clustering

Maintains separation between infrastructure and tenants

Virtual SAS

Scale-Out File Server for file based storage

Host Based Backup of Shared VHDXIn Windows Server 2012 R2 the backup story for Shared VHDX clusters was to use a guest agent• Now you can backup shared VHDX clusters

as easily as any other virtual machine

Online Resize of Shared VHDXYou can now resize shared VHDX virtual hard disks while the guest cluster is running

Demo: Storage Availability

Replica Support for Hot Add of VHDXWhen you add a new virtual hard disk to a virtual machine that is being replicated – it is automatically added to the not-replicated set. This set can be updated online.

Set-VMReplication "VMName" -ReplicatedDisks (Get-VMHardDiskDrive "VMName")

Runtime Memory ResizeDynamic memory is great, but more can be done.

For Windows Server Technical Preview 3 / Windows 10 guests, you can now increase and decrease the memory assigned to virtual machines while they are running.

Hot add / remove of network adaptersNetwork adapters can be added and removed from Generation 2 virtual machines while they are running.

Demo: Hot Add

Rolling Cluster UpgradeYou can now upgrade a 2012 R2 Hyper-V cluster to Windows Server Technical Preview 3 with:• No new hardware• No downtime• The ability to roll-back safely if needed

New VM Upgrade ProcessWindows Server 2012 R2:• Hyper-V automatically upgrades virtual

machines to the latest version• No ability to roll-back the upgrade process

New VM Upgrade ProcessWindows 10 / Server Technical Preview 3:• Hyper-V will not automatically upgrade

virtual machines• Upgrading a virtual machine is a manual

operation that is separate from upgrading the host

• Individual virtual machines can be moved back to earlier versions, until they have been manually upgraded

Demo: Upgrade

Operational Improvements

Production CheckpointsDelivers the same Checkpoint experience that you had in Windows Server 2012 R2 – but now fully supported for Production Environments• Uses VSS instead of Saved State to create

checkpoint• Restoring a checkpoint is just like restoring

a system backup

PowerShell Direct to Guest OSYou can now script PowerShell in the Guest OS directly from the Host OS• No need to configure PowerShell Remoting• Or even have network connectivity• Still need to have guest credentials

ReFS Accelerated VHDX OperationsTaking advantage of an intelligent file system for:• Instant fixed disk creation• Instant disk merge operations

Hyper-V Manager & PowerShell ImprovementsMultiple improvements to make it easier to remotely manage and troubleshoot Hyper-V Servers:• Support for alternate credentials• Connecting via IP address• Connecting via WinRM

Demo: Operational Improvements

Cross version management• Hyper-V Manager: Able to manage

Windows Server 2012, 2012 R2 and Technical Preview 3 from a single console

• Hyper-V PowerShell: Windows 10 and 2012 R2 modules included in-box (v1.1 and v2.0)

Changing how we handle VM servicingWindows 8.1 / Server 2012 R2:• VM drivers (integration services) updated

with each new host release• Require that VM driver version matches

the host• Drivers shipped with host operating

system

Changing how we handle VM servicingWindows 10 / Server Technical Preview 3:• VM drivers (integration services) updated

when needed• Require latest available VM drivers for that

guest operating system• Drivers delivered directly to the guest

operating system via Windows Update

Enhancing the platform

VM Configuration ChangesNew virtual machine configuration file• Binary format for efficient performance at

scale• Resilient logging for changesNew file extensions• .VMCX and .VMRS

Hypervisor power management improvements

Updated hypervisor power management model to support new modes of power management.

SummaryLots of new functionality in Windows Server Technical Preview 3 and Windows 10!• More to come in the future!• Please try out the new functionality – and

provide us with feedback!• Talk to me at @VirtualPCGuy
