Even though SC 2012 R2 and WS 2012 R2 are not released yet Microsoft published a guide to setup lab for Hyper-V Network Virtualization. There are no screenshot in the guide but you can have a sneak peak preview of the architecture of the new Multi-Tenant NVGRE Gateway. Check it out here.
Microsoft has released a tool that will help you plan your capacity for Hyper-V Replica. The tool and the documentation for it you can find here.
The last issue I’ve stumbled upon with System Center is with VMM component.
- You have SCVMM 2012 SP1 UR2 installed
- You have Windows Server 2012 Hyper-V for hosts
- You use SMB 3.0 share for storing virtual machines
- Some or all of your virtual machines does not use FQDN path to their vhd/x files
- You’ve added your File Server in VMM by FQDN or NetBIOS Name
- You receive the following error: Error (13924) The highly available virtual machine (VMNAME) is not supported by VMM because the virtual machine uses non-clustered storage.
- Some or all of your virtual machines show as Unsupported Cluster Configuration
I’ve managed to resolve this issue by executing the following steps:
1. Make sure you’ve added your file server in VMM by FQDN. If it is not added by FQDN you have to add it.
2. Create new share. You can create it on the same server. Give the share appropriate permissions.
3. Locate the new share in VMM. Add it as storage location to your hosts/clusters.
4. After is added make sure it show green in the properties of the hosts/clusters.
5. Storage migrate all your virtual machines from the old share to new share. For the machines with status Unsupported Cluster Configuration you can change the status to Running by live migrating them trough the Failover Cluster console.
6. After storage migration of each virtual machine refresh it and make sure in the properties of the machine in Status tab all is green.
7. After successful migration of all virtual machines you can remove the old share from the hosts/clusters and delete it from the File Server.
I’ve also may had problems with the permissions on the old share but it is easier to create new share than fixing permissions on existing share with running virtual machines.

Software I’ve used:
- Windows Server 2012 with latest updates
- SCVMM 2012 SP1 UR2
- File Server with SMB share
If you are working in one of those companies that are building IaaS there are two guides from Microsoft to help you with the basics. Check them out:
These days I’ve managed to get my hands on another Hyper-V book and review it. These book reviews aim to give you more insight so you can make your mind if this book is for you.
The books starts at a very basic level by explaining what is Virtualization and the basic concepts of Hyper-V. After that as usual there is a chapter for planning, designing and implementing so you can get a grasp on the basic features of Hyper-V. The third chapter is for Hyper-V Replica which is a very popular feature since the release of Hyper-V 3.0. Network and Storage have their own chapters as there are a lot of improvements there. Unfortunately in the Network chapter there is not detailed information about Network Virtualization (NVGRE) which is becoming very popular topic. PowerShell is implemented in every enterprise Microsoft product and because of that the author of the book hasn’t missed to place a chapter about automation with PowerShell. The next three chapters include more advanced content. You can find a chapter on how to use VMM 2012 to manage Hyper-V, a chapter on how to achieve high availability with Hyper-V and a chapter with best practices for securing Hyper-V. The last chapter that you will find in the book is about Backup and Recovery. It is interesting how in real world topic like Backup and Recover is also left last . It may not be the most attractive part of Hyper-V and servers in general but it is something that we should take care good.
As a summary the book aims not so much to show you how to configure a certain feature but more to explain you the capabilities of Hyper-V in order to get most of them in your specific environment. I would recommend the book to engineers who just start to work with Hyper-V 3.0, to engineers who had little experience with Hyper-V 2.0 and now are facing the challenge to migrate to 3.0 and at last but not least to engineers who have been working with “the other guys” and now are converting to Hyper-V 3.0. If you think this book is for you can find in one of the following stores:
