However, Windows detected these vCPUs as separate processors not cores and it could use only 2 of them. It means that Windows 10 is able to use only 2 cores no matter how many of them you will add. At the same time, a virtual server running Windows Server on the same hypervisor can see all 16 vCPUs allocated to it. However, this restriction is not related to the number of cores.
In order to improve the performance of your virtual machine, you can use a processor with more cores. Most hypervisors can provide vCPUs as processors, processor cores or even threads. In my KVM virtual machine running Windows 10 , all assigned virtual cores are considered as separate processors. Save the configuration file and start the virtual machine. CPU Hot Plug. Remember limitations and requirements. This frequency is the maximum frequency for a virtual machine, even if this VM is the only VM running on the ESXi host or cluster with more free processor resources.
The set limit is true for all virtual processors of a VM. If a VM has 2 single-core processors, and the limit is MHz, then both virtual processors work with a total clock speed of one million cycles per second MHz for each core. This parameter defines the priority of resource consumption by virtual machines Low, Normal, High, Custom on an ESXi host or resource pool. Hardware virtualization. Select this checkbox to enable nested virtualization. This option is useful if you want to run a VM inside a VM for testing or educational purposes.
Performance counters. This feature is used to allow an application installed within the virtual machine to be debugged and optimized after measuring CPU performance.
Scheduling Affinity. This option is used to assign a VM to a specific processor. Using this option is deprecated in vSphere 7. On the following screenshot, you see processor configuration for the same Ubuntu VM that was configured before in vSphere Client.
In the graphical user interface GUI of VMware Workstation, you should select the number of virtual processors sockets and the number of cores per processor. The number of total processor cores logical cores of physical processors on an ESXi host or cluster is calculated and displayed below automatically.
In the interface of vSphere Client, you set the number of total processor cores the CPUs option , select the number of cores per processor, and then the number of virtual sockets is calculated and displayed. The commands are used for VMs that are powered off. To configure a VM to use two single-core virtual processors two virtual sockets are used , use the command:. In the following example, you see how to configure a VM to use two dual-core virtual processors 2 sockets are used :.
In my case, I check the Ubuntu If you need to reduce the number of processors sockets for a VM, use the same command as shown before with less quantity. For example, to set one processor socket for a VM, use this command:. Task automation is important and convenient if the number of virtual machines to configure is high.

Maximum number of cores. 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. Consult your Microsoft licensing provider with all details to obtain confirmation that the interpretation is correct with respect to the actual licenses you have So many lovely little variations of license types.
Make sure you know the details of the host hardware as the licenses are often dependant on the number of CPU sockets with server licensing. Although I believe there are other combinations. Read through the detail carefully as it's confusing. Many people I have worked with over the years have been causal and quickly misunderstood the terms of the licenses having never actually read the detail. It's tedious but important.
Be mindful of restrictions on the portability of licenses in a virtual environment. Software licensing still mostly seems to be heavily dependant on being associated with physical hardware.
If you want the VMs to move, you ideally need to have SA for license mobility. The only condition that MS says is that if a host fails, you can move, but you cannot move it again for 90 days I assume that if the host fails again, it will invalidate the second part. If both servers are beefy then no issue.
However, I think if you license both server for the max VMs that you will or maybe can run, it should be OK - this is a grey area. I know its better to go with Data center license, but we already purchased standard license on last year so my organization want to use this existing licenses.

A total of 50 users will be accessing the server. Remember that a single Standard edition license covers up to two physical processors and up to two instances of virtual machines. Since the requirement is to run 8 instances of virtual machines, we need four Standard edition licenses. If we decided to use the Datacenter edition in this scenario, a single license with 50 CAL would be enough to cover our needs, because the Datacenter edition license supports an unlimited number of virtual instances and up to two physical processors.

VMware Cores per Socket Configuration Best Practice
Also, keep in mind that there are limitations to the free Developer and Express editions. Developer edition has the same capabilities as Enterprise, but the licensing agreement limits the ways in which you can use Developer edition. The Express edition does not have the usage limits that Developer edition does, but it does have limits on scale and functionality.
For containers, each v-core or virtual processor, virtual CPU, virtual thread allocated to the container must be licensed, with a minimum of 4 license units. Keep in mind with Software Assurance Microsoft includes a limited number of Big Data node core licenses. For example, if you purchase a 4 core Enterprise Edition license for your Master Instance, you are entitled to 8 times the 4 cores, or 32 cores for your Big Data nodes.
Physical servers do not count hyperthreading when licensing SQL server. Licensing is based only on the number of physical cores on the server. If the logical CPUs are from virtualization servers that are hyperthreaded, then you are licensing based on hyperthreaded CPUs.
A vCPU is connected to a virtual socket. CPU overcommitment is the situation when you provision more logical processors CPU cores of a physical host to VMs residing on the host than the total number of logical processors on the host. NUMA non-uniform memory access is a computer memory design used in multiprocessor computers.
The idea is to provide separate memory for each processor unlike UMA, where all processors access shared memory through a bus. At the same time, a processor can access memory that belongs to other processors by using a shared bus all processors access all memory on the computer. A CPU has a performance advantage of accessing own local memory faster than other memory on a multiprocessor computer. These basic architectures are mixed in modern multiprocessor computers. Processors are grouped on a multicore CPU package or node.
Processors that belong to the same node share access to memory modules as with the UMA architecture. Also, processors can access memory from the remote node via a shared interconnect.
Processors do so for the NUMA architecture but with slower performance. This memory access is performed through the CPU that owns that memory rather than directly. An example. Each CPU has 6 processor cores. This server contains two NUMA nodes. The total number of physical CPU cores on a host machine is calculated with the formula:. If hyper-threading is supported, calculate the number of logical processor cores by using the formula:. Finally, use a single formula to calculate available processor resources that can be assigned to VMs:.
For example, if you have a server with two processors with each having 4 cores and supporting hyper-threading, then the total number of logical processors that can be assigned to VMs is. As for virtual machines, due to hardware emulation features, they can use multiple processors and CPU cores in their configuration for operation. For example, if you configure a VM to use 2 vCPUs with 2 cores when you have a physical processor whose clock speed is 3.
The maximum number of virtual processor sockets assigned to a VM is If you want to assign more than virtual processors, configure a VM to use multicore processors. The maximum number of processor cores that can be assigned to a single VM is in vSphere 7. A virtual machine cannot use more CPU cores than the number of logical processor cores on a physical machine.

Is it any surprise that people get confused with MS licensing? If you have ever had to deal with MS licensing "experts" on the phone you will know that if you phone 10 times you will probably get 10 different answers!
To me, the diagram shows 1 host and 9 VMs. That is fine, but not the 2 hosts and 7 VMs mentioned in the post. Kudos to Bryce, who I think is correct here when he says "Two virtual server instances on the same host. As far as I have researched, this is not legitimate. License Mobility is not VM mobility. Actually 7 VMs will not fit so we make a diagrams for 6 VMs per host 2 hosts. What type of "paper" license you have. Microsoft have since stopped issuing paper license since Windows Are the cost and number of CALs involved?
Most of us are sometimes confused as CALs are almost never mentioned. Do you intend to do Windows Clustering you may need to read up on Windows clustering and its requirements? All physical processors need to be licensed. Each license covers up to two physical processors. If you run all of the permitted instances the instance in the physical OSE can only be used to manage the virtual OSEs.
I will always ask people to get written confirmation from their Microsoft sales representatives as whatever we say here is advise and not legally supported I do seek your kind understanding This may not be easy but this have led to much interpretations.

This means that a maximum of 25 users amongst 50 computers can access the Windows Server Essentials edition.
For example, you have 20 users rotating randomly amongst 25 computers accessing the Server Essentials edition, without any problem. A common question at this point is what if the organization expands and increases its users and computers? In these cases Microsoft provides an upgrade path allowing organizations to upgrade to the Windows Server Standard or Datacenter edition license and perform an in-place license transition.
Once the transition is complete, the user limitation, and other features are unlocked without requiring migration or reinstallation of the server. Companies upgrading to a higher edition of Windows Server should keep in mind that it will be necessary to purchase the required amount of CALs or DALs according to their users or devices. Administrators will be happy to know that it is also possible to downgrade the Standard edition of Server to the Essentials edition.
For example, it is possible to run Essential edition of Server as virtual machine utilizing one of two available virtual instances in Standard edition as shown in the figure below. This eliminates the needs to purchase Essential edition of Server Download Now!
Unlike Windows Server Essentials non-R2 , you can now run a single instance of a virtual machine. The server licensing rights have been expanded, allowing you to install an instance of Essentials on your physical server to run the Hyper-V role with none of the other roles and features of the Essentials Experience installed , and a second instance of Essentials as a virtual machine VM on that same server with all the Essentials Experience roles and features.
Definition of a socket is a CPU or physical processor. Logical cores are not counted as sockets. A single license of Standard and Datacenter edition covers up to two physical processors per physical server. Standard edition allows up to 2 virtual instances while the Datacenter edition allows unlimited number of virtual instances. For example, a Windows Server R2 Standard edition installed on a physical server with one socket CPU can support up to two instances of virtual machines.
