Microsoft’s new VMware migration offer for Windows Server 2016

Microsoft just announced a new VMware migration offer for Windows Server 2016. In a nutshell: If you switch from VMware to Hyper-V from during September 1, 2016, through June 30, 2017, you can get free Windows Server Datacenter licenses when buying Windows Server Datacenter + Software Assurance. That ultimately means customers only pay for Software Assurance.

Microsoft also released a new TCO calculator to compare VMware and Hyper-V, which you can find here: VMware Shift

There are also a lot of great technical reasons to switch from VMware to Hyper-V. Check out my blog post about What’s new in Windows Server 2016 Hyper-V to get an overview about new features.

To get started just follow these steps:

To be eligible for the VMware migration offer, customers must follow these steps:

  • Step 1: Engage your account executive or sales rep to begin the process.
  • Step 2: Identify virtualized workloads to migrate and specify the Windows Server Datacenter cores required.
  • Step 3: Provide your account executive proof of eligibility. (Offer applicable to customers migrating from VMware to Microsoft).
  • Step 4: Engage your partner to start the migration process.
  • Step 5: Receive free Windows Server Datacenter licenses with Software Assurance and pay only the cost of Software Assurance to kick start your migration.

Feel free to contact us to help you switch!

Windows Sysprep for Virtual Machines

For using the same system image for different virtual machines or physical computer, Microsoft created a tool called sysprep.exe. Most people should be already familiar with that tool. If not here is the description:

Sysprep prepares a Windows installation (Windows client and Windows Server) for imaging, allowing you to capture a customized installation. Sysprep removes PC-specific information from a Windows installation, “generalizing” the installation so it can be reused on different PCs. With Sysprep you can configre the PC to boot to audit mode, where you can make additional changes or updates to your image. Or, you can configure Windows to boot to the Out-of-Box Experience (OOBE).

This is great so you can sysprep a virtual machine copy the VHD or VHDX file and use it for the first boot of different VMs. In Windows Server 2012 and Windows 8, Microsoft added an addition to sysprep called the mode switch “/mode:vm”. The mode:vm switch allows you to identify the Windows as a Virtual Machine and sysprep.exe will generalize a Virtual Hard Disk (VHD or VHDX) so that you can deploy the VHD as a VHD on the same Virtual Machine (VM) or hypervisor. You must deploy the VHD on a Virtual Machine (VM) or hypervisor with the same hardware profile. For example, if you created VHD in Microsoft Hyper-V, you can only deploy your VHD to Microsoft Hyper-V VMs with a matching hardware profile, and you can only run VM mode from inside a VM.

This will boost the performance and time for the virtual machine for the first startup and installation. This also work of course with virtual machines running on other hypervisors such as VMware or Xen.

Run the following command inside the Virtual Machine (You find sysprep.exe in the  C:\Windows\System32\Sysprep folder):

Now you can copy the VHD or VHDX file from that virtual machine and use it for other VMs.

VMware ESXi 6.0 Enable SSH Service

Enable SSH on VMware ESXi 6.0 via vSphere Client

In another blog post I wrote how you can enable SSH on a VMware ESXi 6.0 host directly on the host it self. In this blog post I show you how you can enable SSH on your VMware ESXi 6.0 host via the VMware vSphere Client.

Open the VMware vSphere client and connected to your ESXi server and open the Configurations tab.

VMware ESXi 6.0 Configuration

On the Configurations tab choose Security Profile.

VMware ESXi 6.0 Security Profile

Open the Properties tab so you cen see the Security Profile properties and the Remote Access services. Here you can enable the SSH Server on the VMware ESXi host.

VMware ESXi 6.0 Enable SSH Service

If you have some issues check the firewall settings on your VMware ESXi host.

If you want to enable SSH on directly on your VMware ESXi host check out the following post: Enable SSH on VMware ESXi 6.0

Enable SSH on VMware ESXi 6.0


I already wrote some blog posts how you can enable SSH access for older VMware ESXi versions such as VMware ESXi 4.1, VMware ESXi 5.0, VMware ESXi 5.1 and VMware ESXi 5.5. This post now shows you how you can enable SSH on the VMware ESXi 6.0 host. As in the other versions this is pretty simple. By enabling SSH allows you to remote troubleshoot your VMware ESXi host and also coping files on your server.

On the Login screen of your VMware ESXi host press “F2”

VMware ESXi Logon Screen

It will ask you about username and password to login to the VMware ESXi server:

VMware ESXi 6.0 Login

After the login go to the Troubleshooting Options on the System Customization page.

VMware ESXi 6.0 Troubleshooting Options

You can now enable SSH on your VMware ESXi 6.0 host. After you have enabled SSH you can connect to the ESXi host via your favorite SSH client.

If you want to enable SSH on your VMware ESXi host directly from the VMware vSphere Client you should have a look at the following post: Enable SSH on VMware ESXi 6.0 via VMware vSphere Client

Microsoft Azure Site Recovery Services

Disaster Recovery using Azure Site Recovery

Nearly a year ago Microsoft released a Disaster Recovery solution called Hyper-V Recovery Manager. This was basically a hosted orchestration engine in Microsoft Azure which allowed you to orchestrate datacenter failovers using the in Hyper-V build in feature called Hyper-V Replica.

Microsoft Azure Site Recovery

In 2014 Microsoft invested a lot of work and time to improve this service and in January 2014 HRM changed the name to Azure Site Recovery (ASR).

  • In January 2014 Microsoft announced GA of the Azure Site Recovery service which allowed you to use it for DR Orchestration between on-premises Hyper-V sites using Hyper-V Replica
  • In July 2014 Microsoft acquired a company called InMage and integrated DR Orchestration between on-premises VMware sites using the InMage solution.
  • In October 2014 Microsoft announced the GA for Azure Site Recovery DR Orchestration between Hyper-V on-premises and Microsoft Azure.

At TechEd Europe, Microsoft announced some new stuff coming in the next couple of months.

  • In November 2014 Microsoft will offer a public preview for Azure Site Recovery using SAN Replication. This allows you to use your existing SAN replication and orchestrate your DR with Microsoft Azure Site Recovery.
  • In 2015 Microsoft will allow you to use Azure Site Recovery to replicate your VMware and physical servers to Microsoft Azure.
  • With Update Rollup 4 for System Center 2012 R2 and Azure Pack, Microsoft integrated Azure Site Recovery as a plan or Add-on property for VM clouds. This allows service providers to offer Azure Site Recovery to customers as an option of a VM Cloud plan or Add-On.

Microsoft Azure Site Recovery Services

This is just a quick overview about the possibilities you have with Azure Site Recovery. I will cover some advanced scenarios in with a series of blog posts in the next couple of weeks. Until then I would recommend you to watch the session with Michel Lüscher and me at System Center Universe Europe where we talked about the Azure Site Recovery solutions before the TechEd announcements.



System Center Universe Europe 2014

My sessions from System Center Universe Europe 2014 available on Channel9

As I already posted I was presenting at System Center Universe Europe 2014 (SCU Europe) in Basel this year. Microsoft now made the recordings available on Channel9 and you can now watch them for free.

Disaster Recovery with Azure Site Recovery

Together with Michel Lüscher (Architect at Microsoft) I was showing how you can deploy a fully automated Disaster Recovery solution based on Microsoft Hyper-V Replica, System Center Virtual Machine Manager and Windows Azure Hyper-V Recovery Manager.

Software Defined Networking – Comparison of different solutions

Together with Walter Dey (Former Cisco Distinguished Engineer) I held the session about different SDN (Software Defined Networking) solutions on the market. This session will provide an overview about Software-Defined Networking and compare different solutions such as Microsoft Hyper-V Network Virtualization based on NVGRE and Cisco VXLAN and VMware NSX.
