Hyper-V vNextTomica Kaniški, Vipnet

Hyper-V Manager improvements

• WinRM connection (instead of WMI in previous versions)

• support for alternate credentials

‐ CredSSP needs to be enabled on the server and client

• use IP address to connect to a Hyper-V host

• ability to manage downlevel versions of Hyper-V(2012 and 2012 R2) from the new/sameHyper-V Manager Console

VM version/upgrade

• new VM version (not generation!) – 6.0/6.2/7.0

‐ Windows Server 2012 R2 VMs were 5.0

• Hyper-V will not automatically upgrade VMs

• upgrading a virtual machine is a manual operationthat is separate from upgrading the host

• individual virtual machines can be moved backto earlier versions, until they have been manuallyupgraded

‐ Update-VMConfigurationVersion

‐ or GUI, of course

Configuration file changes

• new virtual machine configuration file

‐ binary format for efficient performance at scale

‐ resilient logging for changes

‐ new file extensions

.VMCX and .VMRS

Integration services

• drivers (integration services) delivered directly to the guest operating system via Windows Update

• no vmguest.iso anymore…

• however, keep one copy local, just to be safe(and for upgrades/isolated environments)

Runtime memory resize

• dynamic memory was/is a great feature, but…

• now you can increase and decrease the memory assigned to virtual machines while they are running

Network adapters

• hot add/remove of network adapters

‐ network adapters can be added and removed from (Generation 2)virtual machines while they are running

• network adapter naming

‐ you can name individual network adapters in the virtual machine settings – and see the same name inside the guest operating system(hosting, service providers)

‐ (host) Add-VMNetworkAdapter -VMName "ATD11_Upgraded" -SwitchName "LAN" -Name"ATD11_Public" -Passthru | Set-VMNetworkAdapter -DeviceNaming On

‐ (guest) Get-NetAdapterAdvancedProperty | ?{$_.DisplayName -eq "Hyper-V Network Adapter Name"} | select Name, DisplayValue

Linux & Secure Boot

• Secure Boot support for Linux

‐ kernel code integrity protections for Linux guest operating systems (Ubuntu 14.04 and later, and SUSE Linux Enterprise Server 12)

Set-VMFirmware "Ubuntu" -SecureBootTemplate MicrosoftUEFICertificateAuthority

Production checkpoints

• two kinds of checkpoints – Standard and Production

‐ Standard delivers the same "legacy" experienceyou had in Windows Server 2012 R2

‐ "new one" (Production) is fully supportedfor production environments

• you can choose which to use or turn them offcompletely

• uses VSS instead of Saved State to create checkpoint

• restoring a checkpoint is just like restoring a system backup

• "ON" by default!

Cluster OS Rolling Upgrade

• easily upgrade a Hyper-V or Scale-Out File Server failover cluster(without downtime or "migration")

• stop the Cluster-Aware Updating role, drain and remove nodes and replace them with new ones

• when it's all done – pass the "point of no return" (i.e. upgrade the clusteritself) by using PowerShell cmdlet Update-ClusterFunctionalLevel

PowerShell Direct

• run commands inside VM directly through VMbus (no network needed!)

Other improvements (1)

• Nested Virtualization

‐ perfect for demos, training and… Azure

‐ run Hyper-V (and your entire datacenter ) inside a single virtual machine

• Hot-Add disks to Hyper-V Replica

‐ any new disk added to a VM being replicated gets added to the not-replicated set -> replication continues and everything resynchronizes

• new Shared VHDX format (VHDS)

‐ can be resized while "online"

Other improvements (2)

• Virtual TPM & Shielded VMs

‐ encrypt the contents of your VMs using BitLocker for secure hosting outsideof your datacenter (cloud?)

‐ with Shielded Virtual Machines enable you to run VMs only in fabrics that are designated as owners of that virtual machines

• Host Resource Protection

‐ dynamically identifies “rough” virtual machines and reduces their resource allocation (Azure feature)

• Storage Replica

‐ replicated storage for files or VMs, within the same cluster or to another one

Other improvements (3)

• Virtual Machine Storage Resiliency

‐ storage fabric outages no longer mean that virtual machines crash – they getpaused and resumed automatically in response to storage fabric problems

‐ Virtual Machine gets paused until the storage comes back or fails over

• Virtual Machine Cluster Resiliency

‐ virtual machines running on the node that fell out of the cluster are kept alive until the node joins back into the cluster

‐ if the cluster node does not come back within four minutes, the virtual machines failover to another Hyper-V node

Other improvements (4)

• Windows and Hyper-V Containers

‐ operating system-level virtualization within environment that has its own process and network space, instead of creating full virtual machines

Romeo Mlinar, 17:05 (D5)

• Nano Server

‐ new installation option of Windows Server, fully optimizedfor large scale deployments, automation and remoteadministration
