Automating the deployment of Hyper-V hosts with VMM 2016 with Baremetal deployment

To deploy a new Hyper-V host from bare metal, the following simple steps are carried out by System Center 2016 Virtual Machine Manager (VMM) :

  1. VMM Discovers the physical computer through out-of-band management (BMC)
  2. VMM Installs an OS image on the physical computer using a previously created physical computer profile.
  3. VMM Enables the Hyper-V role on the physical computer.
  4. VMM Brings the computer under VMM management as a managed Hyper-V host.

Now in order for that to happen, let’s see what pre-requisites you are required to provide first:

  1. DNS and Active Directory
    Create DNS entries and Active Directory account for the machine names.
  2. BIOS

    a. Set up the BIOS on the machine to support virtualization: Configuring the BIOS boot order to boot from (PXE)-enabled network adapter as the first device.
    b. Configure the BMC settings. Configure the logon credentials and IP address settings for the BMC on each computer.
  3. Add a PXE server environment: A PXE server integrated to VMM is required for Bare Metal deployment.
  4. Add resources to VMM library: Add a generalized virtual hard disk with an suitable OS to use as the base image, and driver files that will be added to the during installation of the OS.
  5. Create a Run As account. In VMM create a Run As Account with permissions to access the BMC.
  6. Create Physical Computer profiles: In the VMM library, create one or more physical computer profiles. These profiles include configuration settings, such as the location of the operating system image, and hardware and OS settings.


Now let’s have a look on the step by step to provision a Hyper-V host using Baremetal Deployment:

  1. Click Fabric > Servers > Home > Add > Add Resources > Hyper-V Hosts and Clusters.
  2. In the Add Resource Wizard > Resource location, select Physical computers to be provisioned as virtual machine hosts.
  3. In Credentials and Protocol select the Run As account with permissions to access the BMC. In the Protocol list, click the out-of-band management protocol that your BMCs use. If you want to use Data Center Management Interface (DCMI), click Intelligent Platform Management Interface (IPMI). Although DCMI 1.0 is not listed, it is supported. Make sure the correct port is selected.
  4. In Discovery Scope, enter the single IP address, the IP subnet, or the IP address range that includes the IP addresses of the BMCs

Note:

  • If you specify a single IP address, when you click Next, the computer is restarted.
  • If you specify an IP address range, when you click Next, information about the computer is displayed, and you can confirm that you specified the computer that you meant to.

4a. If you specified an IP subnet or IP address range the Target Resources page appears. Select the BMCs you want to provision as Hyper-V hosts.

  1. In Provisioning Options, click a host group for new Hyper-V hosts. Select the physical computer profile you want to apply.
  2. In Deployment Customization, provide information for each computer that you want to provision as a Hyper-V host:

Note: To remove a BMC from the list, select it and then click Remove.

For each BMC IP address in the list:

    • Click the BMC IP address and specify a unique computer name, without wildcard characters.
    • Select or clear Skip Active Directory for this computer name. The Active Directory check prevents deployment if the computer account already exists.
    • For each BMC IP address in the list:
    • Click on the Network Adapter (on the left) to modify the configuration, or fill in more information. You can specify the MAC address of the management NIC (not the BMC) and static IP settings for this network adapter.
    • To specify an IP address select a logical network and an IP subnet if applicable. If the selected IP subnet includes IP address pool, you can check Obtain an IP address corresponding to the selected subnet. Otherwise, type an IP address that’s within the logical network or its subnet.
    • Configure the adapter settings for each network adapter. You must specify any information that is missing for the adapters.
    • When all information for the listed BMC are completed, click Next.
  1. In Summary, confirm the settings, and then click Finish to deploy the new Hyper-V hosts and bring them under VMM management.

Make sure that all steps in the job have a status of Completed.

  1. To confirm that the host was added click Fabric > Servers > All Hosts > host group, and verify that the new Hyper-V host appears in the group.

 

Note: Nano Server is not a supported OS for infrastructure-related roles like Hyper-V. I recommend that you use Windows 2016 Core Server version

Windows 2016 released and with it Hyper-V and System Center

September 27, 2016 Leave a comment

Microsoft released today at the Microsoft Ignite conference in Atlanta the newest release of Windows Server 2016!

Windows Server 2016 is jam-packed with innovation and customer response has been overwhelming, with more than half a million devices running the final Technical Preview. These customers range from large global enterprises to private cloud hosters to organizations of every size from every corner of the globe – Erin Chapple, General Manager, Windows Server

 

Windows Server 2016 delivers powerful innovation across three areas:

  • Advanced Multi-layer Security: Use Shielded Virtual Machines to help protect your virtual machines from a compromised fabric as well as improve your compliance. Shielded Virtual Machines are encrypted using BitLocker and will run on healthy hosts. To help prevent attacks and detect suspicious activity with new features to control privileged access, protect virtual machines and harden the platform against emerging threats.Watch an introduction to Shielded Virtual Machines
  • Software-defined Datacenter with Hyper-V: Run your datacenter with the utmost confidence with an automated, resilient server operating system. Azure utilises Windows Server and Hyper-V at a massive scale. Windows Servers delivers a more flexible and cost-efficient operating system for any datacenter, using software-defined compute, storage and network features inspired by Azure. Explore server virtualization with Hyper-V
  • Cloud-ready Application Platform: Run your existing apps on Windows Server 2016 without modifying them. Take advantage of enhanced security and efficiency features in the fabric. Applications are at the heart of every organization and its ability to serve customers and compete effectively for their loyalty.  Windows Server 2016 delivers new ways to deploy and run both existing and cloud-native applications – whether on-premises or in Microsoft Azure – using new capabilities such as Windows Server Containers and the lightweight Nano Server deployment option.  Learn more about containers  and Learn more about Azure Service Fabric on Windows Server 2016

Hyper-V 2016 Tp5: Hyper-V Manager Console new features

Here are some important information and improvements Microsoft released for Hyper-V Manager in Tp5:

  • Alternate credentials support. You can now use a different set of credentials in Hyper-V Manager when you connect to another Windows Server 2016 TP5 or Windows 10 remote host. You can also save these credentials to make it easier to log on again.
  • Previous version management: the New Hyper-V Manager will allow you to manage versions manage computers running Hyper-V on Windows Server 2012/R2 and Windows 8.x client version.
  • Updated management protocolHyper-V Manager has been updated to communicate with remote Hyper-V hosts using the WS-MAN protocol, which permits CredSSP, Kerberos or NTLM authentication. When you use CredSSP to connect to a remote Hyper-V host, you can do a live migration without enabling constrained delegation in Active Directory. The WS-MAN-based infrastructure also makes it easier to enable a host for remote management. WS-MAN connects over port 80, which is open by default.
  • No more Integration services for Windows Virtual Machines. Updates to integration services for Windows guests are distributed through Windows Update. For service providers and hosting companies, this puts the control of applying updates into the hands of the tenants who own the virtual machines. Customers (tenants Administrators) can now update their Windows virtual machines with all updates, including the integration services, using a single method.
  • Integration services for Linux and FreeBSD Virtual Machines. Hyper-V supports both emulated and Hyper-V-specific devices for Linux and FreeBSD virtual machines. Linux Integration Services (LIS) or FreeBSD Integration Services (BIS) , the collection of drivers that are required to run Hyper-V-specific devices, has been added to the Linux kernel and is updated for new releases, but Linux distributions based on older kernels may not have the latest enhancements or fixes. Microsoft provides a download containing installable LIS drivers for some Linux installations based on these older kernels.
    Note: As some Linux distributions include versions of LIS, make sure you install the latest downloadable version of LIS, if applicable, for your installation.

Hyper-V. CSV Volumes pause states 5120‏: Workaround

 

Microsoft is aware that after installing KB3126593 (MS16-014) there may be an issue that causes loss of network packets.

This may cause Cluster Shared Volumes (CSV) on the nodes Failover Clusters to going into a paused state with an event ID 5120 in the System event log what indicates “Status c000020c – STATUS_CONNECTION_DISCONNECTED”. 

You will also find that, on the node that owns the CSV volume(s), there will be an event 7031 with the source: “Service Control Manager”, which indicates “The Windows Firewall Service terminated unexpectedly”. 

Troubleshooting Cluster Shared Volume Auto-Pauses – Event 5120. https://blogs.msdn.microsoft.com/clustering/2014/12/08/troubleshooting-cluster-shared-volume-auto-pauses-event-5120/

Microsoft is aware of this problem and are working on a fix. But until it is release here is what you could do to get around this issue:

Option 1: Disable the Firewall LOGGING for all profiles (domain, private, public). (just the logging, not the firewall . You don’t want to be un-protected)

1.  Start the Windows Firewall with Advanced Security management console (wf.msc)

2.  Right-click Windows Firewall with Advanced Security on Local Computer and select Properties

3.  For all profiles (Domain, Private, Public), under Logging, click Customize. Set Log Dropped Packets and Log Successful connections to NO.

Option 2. Uninstall https://support.microsoft.com/en-us/kb/3126593 from the systems.

I will post an update once Microsoft releases the Hotfix.
