If you add another virtual machine, where possible, you should keep the same arrangement for the VHDs windoqs that virtual machine. VM properties by FCM. There are no limitations for the number of virtual machines that can be supported on a single CSV volume. If there are no issues, you can configure your virtual machine in the cluster environment.❿

Failover Cluster, planned failover. For example, run the validation tests when you make the following configuration changes to the failover cluster:. Its not 2 VMs per license❿
Setting up Hyper-V Failover Cluster in Windows Server R2. Windows server 2012 r2 standard edition failover cluster free
You will require two or more servers to function as Hyper-V hosts. You can build a new cluster with just one server node. That allows you to build a cluster when you are temporarily short on hardware, albeit without actually having virtual machine high availability HA until you add a second host. Ideally you will use identical servers when you build the cluster.
This will simplify support of the servers, of Windows Server, and of your storage solution more on that later. However, from the Microsoft perspective, the servers need only be fairly similar. The processors must be either all-Intel or all-AMD to allow live migration. Hyper-V does allow you to have mixed generations functionality of processor from the same manufacturer, but to enable live migration you must disable advanced processor features in the virtual processor settings of each virtual machine.
My advice: Keep it simple. Keep the hosts identical and get the newest processor that you can afford. Doing that will probably mean that the processor will still be available after a year when you need to add host capacity to the cluster.
Its 2 VM per physical host. In order to enjoy the 2 OSe, you will need to run them on a Windows server hyper-V host. Furthermore, you may want to speak and get a written confirmation from your authorised MS re-seller to confirm about the licensing with Hyper-V or VMware etc.
However, you may want to get get a written confirmation from your authorised MS re-seller to confirm. In this case, in order to run 7 Windows Server VMs on either of two hosts, each host needs to be licensed for the 7 VMs. Each host will need 4 licenses.
The total licenses required is therefore 8, or one more than what the OP currently has. Buy 1 more and you are covered. I think I would upgrade to a single license of R2 Datacenter and then not worry about how many VMs you can run on the host. Of course, if you are clustering 2 machines, then you will need 2 licenses for Datacenter which makes it a bit more than the cost of those 7 standard licenses.
If you are using fail over clustering forget about using Windows Server R2 standard legally. You need datacenter license on each host. As far as I can tell you do not need SA since that license covers an unlimited number of VM’s on that host. I have seen comments that SA gives you mobility rights, but I am not so sure about that.
If you are using shared nothing migration and replicas than you can get away with server r2 standard as long as you have the right number of licenses to cover your VM’s.
So if you have 4 virtual machines on 2 servers and they could be on either server due to migration non failover clustering you need 2 standard licenses her host. In a clustering scenario I suspect you’d be best served by running the Hyper-V Server on the hardware and running 14 VMs, but you must keep an even number of VMs on each machine for licensing purposes.
The reality is that you might actually be better off getting two DataCenter licenses and then not worry about the number of VMs.
Additionally, you cannot split the virtual machines from a given license across hosts. If you want 1 vm on Host1 and 1 vm on Host2, you still need 2 licenses which gives you room for an additional vm per host.
Starting with fresh licensing, going with Datacenter for unlimited VMs may make sense. Given that 7 licenses already exist, current licensing requirements would be met by purchasing just 1 additional Windows Server Standard license. That would allow 14 VMs one one host, and unlimited on the other, for a net total of 14 that you can safely run in the cluster. I would need to check pricing from Microsoft, but as I recall Microsoft increased the price of Datacenter relative to Standard with The breakeven point used to be 7 VMs, but it is higher now.
I may be in danger of breaking the fourth wall here but there is no location to enter multiple licenses in to windows server. As long as your environment has enough OSE use rights to cover the notional locations of VMs in a cluster then you can be compliant at audit.
The MS audit documentation only asks the OS versions of hosts, guests and if clustering is in use on each host. So yes OSE use rights in batches of two on each host.
Having been through this discussion at Length with Chris Microsoft he linked me this fantastic PDF that does go into the detail you’d need.
This was of particular concern for us because VMware’s documentation listed it, but XenServer’s was a little more ambiguous to my liking. Install the AVMA key in the virtual machine. License Mobility Rights do not apply to the server software. Page 82 explains what is granted under License Mobility Rights, which does not apply to Windows Server here as the rights are not granted. Guest OS VM licenses have to be fully assigned to hardware.
The licenses do not fail over with the VM. You cannot install any additional roles to the Host and preserve the free Guest OS license. Only Hyper-V. As confusing as the licensing plan seems for R2 based on the variety of answers, I can hardly wait for to hit the scene, with it’s ‘core pack’ licensing It’s no wonder there is confusion when things are so poorly written, as if no one would ever confuse the term ‘physical processor’ vs.
I would like to draw your attention to a thread I created on instruction from spiceworks regarding a quizz question about this same topic I found to be misleadingly worded. We just got don Good afternoon and welcome to today’s briefing. Hope you are starting to enjoy the warmer weather up in the north it has been pretty awesome.
That said Security doesn’t sleep and so do we have to keep our systems and our knowledge up to date. We have some Online Events.
Log in Join. Hello, We have total 7 qty. Verify your account to enable IT peers to see that you are a professional. Spice 10 flag Report. Gopal Vembu This person is a verified professional. Spice 2 flag Report. Please clarify on this scenario Thanks in advance..
Hrrmm I think the base idea is right but think there are issues with evenly placing the VMs With these licenses, you apply them to the host.. Thoughts from others? Spice 4 flag Report. That’s two VMs per license.. But you can have multiple licenses per host. Software assurance only comes in if you are upgrading version. Not quite Spice 8 flag Report. Don’t forget about live migrations and 60 days ban for applying license back.
This could x2 amount of virtual machines licensed. Welcome to the wonderful world of MS-Licensing! Leave a Comment Cancel Reply Your email address will not be published. Scroll to Top. The Before you. Users can also download the free Windows Server R2 Licensing update services and failover clustering are not available in the Foundation edition. So if you have 4 virtual machines on 2 servers and they could be on either server due to migration non failover clustering you need 2.
In the meantime: 1. Good luck! Spice 11 flag Report. If the cluster nodes are connected to networks that should not be used by the cluster, you should disable them.
To disable a network, in Failover Cluster Manager, select Networks , select the network, select the Properties action, and then select Do not allow cluster network communication on this network.
Network adapter properties. In the properties for all adapters that carry cluster communication, make sure that the following settings are enabled:. To enable SMB, also ensure that the Server service and the Workstation service are running and that they are configured to start automatically on each cluster node. In Windows Server R2 and later, there are multiple Server service instances per failover cluster node. There is the default instance that handles incoming traffic from SMB clients that access regular file shares, and a second CSV instance that handles only inter-node CSV traffic.
Also, if the Server service on a node becomes unhealthy, CSV ownership automatically transitions to another node. SMB 3. For more information, see Server Message Block overview. The filter is disabled because it can cause issues with Hyper-V clusters which have a Guest Cluster running in VMs running on top of them. This can result in communication issues with the guest cluster in the VM. If you are deploying any workload other than Hyper-V with guest clusters, enabling the NetFT Virtual Adapter Performance Filter will optimize and improve cluster performance.
Cluster network prioritization. We generally recommend that you do not change the cluster-configured preferences for the networks. IP subnet configuration. No specific subnet configuration is required for nodes in a network that use CSV. CSV can support multi-subnet stretch clusters.
Policy-based Quality of Service QoS. We recommend that you configure a QoS priority policy and a minimum bandwidth policy for network traffic to each node when you use CSV. For more information, see Quality of Service QoS. Storage network. For storage network recommendations, review the guidelines that are provided by your storage vendor. In most cases, a LUN used for one set of cluster servers should be isolated from all other servers through LUN masking or zoning.
This provides the highest level of redundancy and availability. If you are implementing a multipath solution for your cluster, work closely with your hardware vendor to choose the correct adapters, firmware, and software for the version of Windows Server that you are running.
