The document summarizes new features in the next version of Hyper-V including improved Hyper-V Manager, ability to dynamically resize VM memory and add/remove network adapters while running, support for Linux secure boot, production checkpoints, cluster upgrades without downtime, PowerShell direct on VMs, and other resiliency and container improvements. It also discusses VM versioning and manual upgrades being required when moving to new versions.

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

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)
