Slides from a session on Hyper-V in Windows Server 2016 at Advanced Technology Days 11 in Croatia.

1. Advanced
Technology Days
18. i 19. studenog 2015., Cinestar Arena Centar

2. Hyper-V vNext

3. 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/same
Hyper-V Manager Console

4. 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 operation
that is separate from upgrading the host
• individual virtual machines can be moved back
to earlier versions, until they have been manually
upgraded
‐ Update-VMConfigurationVersion
‐ or GUI, of course 

5. 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

6. 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) 

7. 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

8. 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

9. 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

10. Production checkpoints
• two kinds of checkpoints – Standard and Production
‐ Standard delivers the same "legacy" experience
you had in Windows Server 2012 R2
‐ "new one" (Production) is fully supported
for production environments
• you can choose which to use or turn them off
completely
• uses VSS instead of Saved State to create checkpoint
• restoring a checkpoint is just like restoring a system backup
• "ON" by default!

11. 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 cluster
itself) by using PowerShell cmdlet Update-ClusterFunctionalLevel

12. PowerShell Direct
• run commands inside VM directly through VMbus (no
network needed!)

13. 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"

14. Other improvements (2)
• Virtual TPM & Shielded VMs
‐ encrypt the contents of your VMs using BitLocker for secure hosting outside
of 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

15. Other improvements (3)
• Virtual Machine Storage Resiliency
‐ storage fabric outages no longer mean that virtual machines crash – they get
paused 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

16. 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 optimized
for large scale deployments, automation and remote
administration
 Tomica Kaniški (), 16:25 (D5)
