VMM supports update of an S2D host or a cluster. You can update individual S2D hosts or clusters against the baselines configured in windows server update services WSUS. See the following sections for detailed information about the new features supported in VMM You can leverage this functionality to reduce your infrastructure expense for development, test, demo, and training scenarios. This feature also allows you to use third- party virtualization management products with Microsoft hypervisor.
With these updates, in scenarios where the organization is managing large number of hosts and VMs with checkpoints — you would be able to observe significant and noticeable improvements in the performance of the job. In our lab with VMM instances managing 20 hosts - each host managing VMs, we have measured up to 10X performance improvement.
This is most useful when the VM does not have any network connectivity or want to change network configuration that could break the network connectivity. Currently, the current console connect in VMM supports only basic session where clipboard text can only be pasted through Type Clipboard Text menu option. The feature automatically improves storage resource fairness between multiple VMs using the same cluster and allows policy-based performance goals.
With the advent of the software defined network SDN , in Windows Server and System Center , the configuration of guest clusters has undergone some change. With the introduction of the SDN, VMs which are connected to the virtual network using SDN are only permitted to use the IP address that the network controller assigns for communication. At any given time, the probe port of only the active node responds to the ILB and all the traffic directed to the VIP is routed to the active node.
Using the new encrypted networks feature, end-to-end encryption can be easily configured on VM networks by using the Network Controller NC. This encryption prevents traffic between two VMs on the same network and same subnet, from being read and manipulated. Being at the heart of providing attestation and key protection services to run shielded VMs on Hyper-V hosts, the host guardian service HGS should operate even in situations of disaster.
This capability enables scenarios such as guarded fabric deployments spanning two data centers for disaster recovery purposes, HGS running as shielded VMs etc. If the primary HGS fails to respond after the appropriate timeout and retry count, the operation will be reattempted against the secondary.
Subsequent operations will always favor the primary; the secondary will only be used when the primary fails. VMM orchestrates the entire workflow. It drains the node, removes it from the cluster, reinstalls the operating system, and adds it back into the cluster.
Bare metal deployment of Hyper-V host clusters : Deploying a Hyper-V host cluster from bare metal machines is now a single step. You can now create production checkpoints for VMs. These checkpoints are based on Volume Shadow Copy Service VSS and are application-consistent compared to standard checkpoints based on saved state technology that aren't. You can't create new templates or deploy new services with the Server App-V app. However, after the upgrade you can't scale out the tier with Server App-V application.
You can scale out other tiers. After it's configure you can create storage pools and file shares on it. In VMM you can use Windows Storage Replica to protect data in a volume by synchronously replicating it between primary and secondary recovery volumes. You can deploy the primary and secondary volumes to a single cluster, to two different clusters, or to two standalone servers. You use PowerShell to set up Storage Replica and run failover. You can configure QoS for storage to ensure that disks, VMs, apps, and tenants don't drop below a certain resource quality when hosts and storage are handling heavy loads.
When you deploy a virtual machine, you might want to run a post-deployment script on the guest operating system to configure virtual network adapters. Previously, this was difficult because there wasn't an easy way to distinguish different virtual network adapters during deployment. Now, for generation 2 virtual machines deployed on Hyper-V hosts running Windows Server , you can name the virtual network adapter in a virtual machine template.
This is similar to using consistent device naming CDN for a physical network adapter. You can provide self-service capabilities for fabric managed by Network Controller. You can provision and manage guarded hosts and shielded VMs in the VMM fabric, to help provide protection against malicious host administrators and malware. Skip to main content.

Storage Storage dynamic optimization This feature helps to prevent cluster shared storage CSV and file shares from becoming full due to expansion or new virtual hard discs VHDs being placed on the cluster shared storage. Support for storage health monitoring Storage health monitoring helps you to monitor the health and operational status of storage pools, LUNs, and physical disks in the VMM fabric.
Support for configuring a Layer 3 forwarding gateway by using the VMM console Layer 3 L3 forwarding enables connectivity between the physical infrastructure in the datacenter and the virtualized infrastructure in the Hyper-V network virtualization cloud. Note You must configure the DCB settings consistently across all the hosts and the fabric network switches.
Performance improvement in host refresher The VMM host refresher has undergone certain updates for performance improvement.
Configuration of fallback HGS Being at the heart of providing attestation and key protection services to run shielded VMs on Hyper-V hosts, the host guardian service HGS should operate even in situations of disaster.
All management networks need to have routing and connectivity between all hosts in that network. Select Create a VM network with the same name to allow virtual machines to access this logical network directly to automatically create a VM network for your management network.
If you want to allocate static IP addresses to network controller VMs, create an IP address pool in the management logical network. If you're using DHCP you can skip this step. Provide a Name and optional description for the pool and ensure that the management network is selected for the logical network. In Network Site panel, select the subnet that this IP address pool will service. In Summary page, review the settings and click Finish to complete the wizard.
You need to deploy a logical switch on the management logical network. The switch provides connectivity between the management logical network and the network controller VMs. Review the Getting Started information and click Next.
Provide a Name and optional description. Select No Uplink Team. If you need teaming, select Embedded Team. In Extensions , clear all the switch extensions. This is important. If you select any of the switch extensions at this stage, it could block the network controller onboarding later.
You can optionally add a virtual port profile and choose a port classification for host management. Use the defaults for load balancing algorithm and teaming mode.
Select all the network sites in the management logical network. Click New Network Adapter. This adds a host virtual network adapter vNIC to your logical switch and uplink port profile, so that when you add the logical switch to your hosts, the vNICs get added automatically.
Provide a Name for the vNIC. Verify that the management VM network is listed in Connectivity. This allows you to take the vNIC adapter settings from the adapter that already exists on the host.
If you created a port classification and virtual port profile earlier, you can select it now. In Summary review the information and click Finish to complete the wizard.
You must deploy the management logical switch on all of the hosts where you intend to deploy the NC. These hosts must be a part of VMM host group that you created earlier Learn more. You can use the following methods:. The following example creates a new self-signed certificate, and should be run on the VMM server. Open the Certificates snap-in certlm. PFX and accept the default to Include all certificates in the certification path if possible. On the File to export page, browse the location where you want to place the exported file, and give it a name.
Request a CA-signed certificate. For a Windows-based enterprise CA, request certificates using the certificate request Wizard.
In addition, the certificate subject name must match the DNS name of the network controller. Otherwise, the communication between Network Controller and the host might not work. Import the service template into the VMM library. For this example we'll import the generation 2 template. Update the parameters for your environment as you import the service template.
Review the details and then click Import. You can also customize properties for objects such as host groups, host clusters, service instances. Type a service name, and select a destination for the service instance. The destination must map to the dedicated host group containing hosts that will be managed by network controller. It's normal for the virtual machine instances to be initially red. Click Refresh Preview to have the deployment service automatically find suitable hosts for the virtual machines to be created.
After you configure these settings, click Deploy Service to begin the service deployment job. You can disable this option. You connect the virtual adapter of a VM to a VM networks. You can use a standard pool or configure a custom pool. For example you could have a template that specifies how to balance HTTPS traffic on a specific load balancer.
Logical switches are containers for virtual switch settings. You apply logical switches to hosts so that you have consistent switch settings across all hosts. VMM tracks switch settings on hosts deployed with logical switches to ensure compliance. Port profiles act as containers for the properties you want a network adapter to have. Instead of configuring properties per network adapter you set up in the port profile and apply that profile to an adapter.
There are two types of port profiles. Virtual port profiles contain settings that are applied to virtual network adapters connect to VMs or used by virtualization hosts. Uplink port profiles are used to define how a virtual switch connects to a logical network. Port classifications are abstract containers for virtual port profile settings. This abstraction means that admins and tenants can assign a port classification to a VM template, while the VM's logical switch determines which port profile should be used.
VMM contains a number of default port classifications. For example there's a classification for VMs that need high bandwidth and a different one for VMs that need low bandwidth.
Port classifications are linked to virtual port profiles when you configure logical switches. Plan to create logical networks to represent the network topology for your hosts.
For example, if you need a management network, a network used for cluster heartbeats, and a network used by virtual machines, create a logical network for each. Review the purposes of your logical networks, and categorize them: - No isolation : For example, a cluster-heartbeat network for a host cluster.
One common way to plan network sites is around host groups and host locations. Determine which logical networks will use static IP addressing or load balancing, and which logical networks will be the foundation for network virtualization. For these logical networks, plan for IP address pools. Static IP : Logical network that will use static IP addressing, for example, a network that supports host cluster nodes.
