This article is Part 2 in a two-part series on building a FREE Hyper-V Server 2012 Cluster to support highly available virtual machines as a foundation to a Private Cloud solution. If you missed it, be sure to check out Part 1 of this article series on the initial steps for building Hyper-V Server 2012 hosts in a Failover Cluster configuration.
In this article, we’ll walk through provisioning highly available virtual machines on our new FREE Hyper-V Server 2012 cluster and testing Live Migration failover scenarios.
It’s Time to Build Highly Available VMs!
Now that we have our Hyper-V failover cluster up and running, it’s time to provision our virtual machines in a highly available configuration. Once provisioned in this manner, highly available virtual machines can failover to other physical nodes within our cluster in both planned and unplanned failover scenarios.
If you’ve installed the Hyper-V Manager and Failover Cluster Manager GUI tools on a Windows Server 2012 management server or Windows 8 admin workstation, you can easily perform these steps remotely using these tools. See my article on the Remote Server Admin Toolkit for Windows Server 2012 to learn how to setup a Windows 8 admin workstation for remote management of Windows Server 2012 and Hyper-V Server 2012 hosts.
However, in this article, we’ll assume that you’ll be performing these tasks from the console of your Hyper-V Server 2012 hosts using our built-in Hyper-V cmdlets and Failover Clustering cmdlets in PowerShell 3.0. PowerShell 3.0 ROCKS and is really quite easy to use for these tasks as you’ll see below.
Here are the steps that we’ll be using to build each highly available virtual machine:
- Create new Virtual Hard Disks (VHDs or VHDXs) in a shared storage location that is accessible to your clustered configuration.
As you may recall from my Part 1 article, we’re using the new SMB 3.0 shared application folder functionality to provide a shared storage location for our highly available VM’s. To create a new virtual hard disk in this shared location, I’ll use the New-VHD cmdlet in PowerShell 3.0:
New-VHD -Path \\CAFSC01\HVCVMStorage\HAVM01.VHDX -Dynamic -Size 127GB
- Now that we have our Virtual Hard Disk(s) sitting in a shared storage location that is accessible from our clustered hosts, next we’ll use the New-VM cmdlet to provision each new Virtual Machine in the same shared storage location:
New-VM -Name HAVM01 -Path \\CAFSC01\HVCVMStorage -Memory 1GB -SwitchName "KEMLABNET01" -BootDevice CD -VHDPath \\CAFSC01\HVCVMStorage\HAVM01.VHDX
- After each new Virtual Machine is provisioned, we can use additional cmdlets, such as Set-VM, Add-VMDvdDrive and Add-VMHardDiskDrive, to set additional VM settings and/or attach additional virtualized storage devices, as necessary.
Since my new Virtual Machine in this example is using a blank Virtual Hard Disk for its storage, I’ll attach an ISO image as a DVD boot device to this VM so that I can install Windows Server 2012 when this VM starts up for the first time:
Add-VMDvdDrive -VMName HAVM01 -Path \\CAFSC01\ISO\WS2012RTM.ISO
- Since the Failover Cluster manages the startup and failover of highly available VMs, we’ll want to disable the Hyper-V Automatic Start Options for each of our VMs in this scenario. This will prevent Hyper-V from trying to directly manage the startup of these VMs and instead rely on the cluster for startup and failover tasks:
Set-VM -Name HAVM01 -AutomaticStartAction Nothing
- Our VM’s are now setup with the necessary VM configuration settings. To add our new VMs to the cluster and make them highly available, we’ll now use the Add-ClusterVirtualMachineRole cmdlet as follows:
Add-ClusterVirtualMachineRole -VirtualMachine HAVM01
- Once you’ve setup your new highly available VM’s you can check their status and bring them online with the following cmdlets:
Start-ClusterGroup –Name “HAVM01”
- Your Virtual Machines will start up and you can now connect to their consoles via the VMConnect.exe command-line tool from a remote Windows Server 2012 management server or Windows 8 admin workstation. VMConnect is included with the Hyper-V Management GUI tools.
VMConnect.exe <Hyper-V Host> <Virtual_Machine_Name>
We can use our VMConnect remote console connection to complete the installation and configuration of the Guest OS within each new virtual machine.
We’re finished … Let’s Test!
Our highly available VMs are up and running in our cluster, so let’s test our failover cluster with a Live Migration planned failover using the Move-ClusterVirtualMachineRole cmdlet. I’ll move one of my highly available VMs to the second physical node in my cluster live while it’s running with the following command line syntax:
Move-ClusterVirtualMachineRole -Name "HAVM01" -Node KEMLABHV07

Most of the IoT Gateway scenarios involve collecting data from machines/processing and pushing data upstream to cloud for further analytics. The gateway hardware varies from Raspberry Pi to Industrial PCs. The document states the process of allowing deploying polyglot data pipelining software with the clear notion of supporting immutability. In his session at @ThingsExpo, Shashank Jain, a development architect for SAP Labs, discussed the objective, which is to automate the IoT deployment process from development to production scenarios using Docker containers.

The cloud. Like a comic book superhero, there seems to be no problem it can’t fix or cost it can’t slash. Yet making the transition is not always easy and production environments are still largely on premise. Taking some practical and sensible steps to reduce risk can also help provide a basis for a successful cloud transition. A plethora of surveys from the likes of IDG and Gartner show that more than 70 percent of enterprises have deployed at least one or more cloud application or workload. Yet a closer inspection at the data reveals less than half of these cloud projects involve production...

Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem" in this scenario: microservice A (releases daily) depends on a couple of additions to backend B (re...

Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
