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

 

Availability: Windows Server 2016 is available for evaluation starting today

Note: Volume licensing customers will be able to download fully licensed software at General Availability in mid-October.

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.

Supercharging performance of your Hyper-V ‏

If you are an expert in Hyper-V or just started playing with it, I recommend you download the Hyper-V ebook provided by Altaro.

The ebook is divided in 2 sections:  (1) Diagnosing and Remediating Performance Issues and (2) Planning is Better than Remediation.

It will help you better plan your next Hyper-V deployment and how could you make the most of your existing deployment, through practical hands-on tips as well as background information you will learn how Hyper-V (and virtualization in general) affects performance and how to find issues in storage, CPU, memory and network components. This is followed by a look at planning hosts, VMs, storage, networking and management for maximum performance.

What the book covers:

  • Diagnosing and remediating Storage, CPU, Memory, and Network performance issues
  • Using Windows Performance Monitor and PAL to facilitate system and VM monitoring
  • Manage planning of Hosts, VMs, Storage, Networking, to minimize the risk of performance issues

Installing Hyper-V role on Windows 2016 Server TP2 MinShell version

As you probably are aware of, Windows 2016 Server TP2, comes with 2 installation options. You also probably have noticed as well that the graphical user interface (GUI) is no longer an option in a default install on the Technical Preview 2.NOt even Start Menu.
install-1

  • Windows Server Technical Preview 2 option, will install the server with MinShell (Minimal Shell no GUI). Assuming that you will manage the host remotely you won’t need graphical interface at all and from a security point of view, it is the better option.

install-4

  • Windows Server Technical Preview 2 (with local admin tools) option, will install the server again with MinShell, but includes Server Manager and the other GUI administration tools, although no desktop experience (traditional desktop), nor start menu.

install-3

To install Hyper-V role in the Windows Server Technical Preview 2 (with local admin tools) option, in the Server Manager console, click on Add roles and features and select Hyper-V.

To install Hyper-V role in the Windows Server Technical Preview 2 option :

in the command prompt, type:

PowerShell

PS: > InstallWindowsFeature Hyper-V

Note: If the installation fails due to “The source files could not be found” error, assuming the Windows Server Technical Preview 2 ISO image connected to the DVD drive (D:), type:

PS: > InstallWindowsFeature Hyper-VRestart Source wim:D:\sources\install.wim:4

install-2

Simple as that!
