A Windows Server Essentials vs Standard comparison is outside the scope of this blog post. CAL licenses are required for both Standard and Datacenter editions. For example, if you have licensed Windows Server Standard for all processor cores of a physical server and install Windows Server Standard on a host with the Hyper-V role enabled, then you can run two VMs with Windows Server Standard.
If you need to run 4 virtual machines on a server, then you need to buy one more license a set of two-core licenses to cover all cores for this server the total number of VMs is four and Windows Server Standard is used in this example. One Standard license covers two virtual machines. If you need to run 4 VMs on a physical server that has two 8-core processors, you must buy 16 dual-core Standard licenses for Windows Server Two license sets cover all cores twice and allow you to run 4 VMs.
If you need to run an odd number of VMs on a host, you need to buy licenses for the next even number of VMs. If you need to run 4 VMs on the same physical server that has two 8-core processors but with the Windows Server Datacenter license, you need to buy 8 dual-core Datacenter licenses for Windows Server VM licensing order: Physical cores must be licensed first and only after that virtual machines must be licensed.
Taking into account the current price for Windows Server licenses, it may be better to buy Windows Server Standard licenses if you are going to run up to 12 virtual machines on a single physical server. If you need to run 14 VMs or more, the more rational decision is to buy Windows Server Datacenter.
VM migration is especially needed if you run VMs in a cluster. In this case you need to buy the number of licenses to cover all VMs on all hosts for each physical server as if you are migrating all VMs from all hosts to one host.
In this case, each VM is licensed to migrate to any host. You can migrate a Windows Server license between physical servers once every 90 days.

We have two physical servers. If you purchase Standard edition today but find you need to expand the virtualization capacity of your licensed server, you can do one of the following: Purchase additional Standard edition licenses and assign them to the same physical server, giving you the rights to run additional instances of Windows Server.
The server must have the appropriate number of licenses assigned to it to ensure coverage of all of the virtual OSEs that are running at any given time. Purchase a Software Assurance Step-up license to Datacenter edition, changing the license to a higher edition that allows unlimited virtual OSEs.
To use this benefit, your underlying license must have Software Assurance. With the Windows Server R2 Standard edition licensing model, you can grow your virtualization environment by either buying a step-up license to Datacenter edition if you have Software Assurance, or by simply buying additional Standard edition licenses and assigning them to the same physical server.
For example, if you have a two-processor server and want to run a total of four VOSEs, you can purchase two Standard edition licenses and assign them to the same server.

We continue to have the unlimited virtualisation licensing. That means if you buy 1 copy of Datacenter for a 2 CPU host any virtualisation and you get unlimited installations of Windows Server or lower any edition for unlimited VMs on that host … no changes there!
