Windows Server licenses can only be assigned to physical devices. Whether we are assigning a license to a physical device running Windows Server or a physical hypervisor running one or more virtual Windows Servers, the Windows Server license is always assigned to the physical device.
On the ‘IO\Microsoft Licenses\Windows Server’ allocation page, servers are grouped into three categories. Those categories include:
1. Clusters: Includes hypervisor clusters and standalone hypervisor hosts:
This view exposes several key data points, including: the number of physical hosts in each cluster, the operating system and version installed on each host, the number of active virtual Windows Servers in the cluster, each host’s name and the number of processors and cores it has, and the number of processors and cores in the cluster.
The virtual Windows Servers within each cluster or residing on each standalone hypervisor host can be seen by clicking on the ‘Show Guests’ button. Physical devices are colored green while virtual devices are colored blue. Clicking on the ‘Show Guests’ button will reveal the first 25 guests in the cluster or on the standalone host. If there are fewer than 25 guests, then all guests present will be revealed. If there are more than 25 guests, then clicking the ‘More Guests’ button will reveal the next 25 guests in alphabetical order. To return to the original host only view, click on the ‘Hide Guests’ button:
To the right of each hosts core count you will see this graphic followed by a number. This represents the total number of active Windows Servers that have run on that host, based on the activity data available from each cluster going back up to 90 days. If a device is identified as MSDN licensed or Excluded, then it is removed from this count.
NOTE: This count should NOT be misinterpreted as the highest number of Windows Servers to run on the host at the same time, i.e. the Windows Server high watermark. If a Windows Server (or System Center) high watermark count is required, then that can be obtained from the ‘Device\Virtualization\Windows High Watermark’ view.
If a Windows Standard license is assigned to a host, then the high watermark count is used to calculate the number of Standard licenses to be “stacked” on that host. If Windows Datacenter license is assigned, then the number of cores installed in the host is used to calculate the number of licenses required. To assign a license to a particular host use the license selection box next to the host’s name:
Movere will only expose the license editions and versions that can be assigned to a host. If the host or any of its guests have Windows Datacenter edition installed, then Movere will only expose the Windows and Core Infrastructure Suite (CIS) Datacenter edition. The same applies to the version, if any of the guests on the host have Windows 2012 installed, then Movere will only expose the 2012 and CIS (and above) versions:
To the right of each virtual guest’s Operating System you will see this graphic followed by a number. This represents the number of physical host(s) that guest has run on based on the activity data available going back up to 90 days. This count does not include cluster migrations, i.e. the host migration count is specific to the hosts within the cluster that the virtual guest currently resides on.
2. Physical: Includes physical devices running Windows Server not in a hypervisor role:
For physical devices running Windows Server, you assign a license using the license selection box next to the device’s name. Movere will only expose the license options that can be assigned. For example, you cannot assign a Windows 2008 license to a server running Windows 2012, but you can assign a version equal or higher than the installed version, e.g. assigning a Windows 2012 license to a device running Windows 2003. Assigning a higher version license is typically done to minimize the number of license versions appearing on the license summary page.
The number of licenses assigned to a physical server is based upon the version and edition assigned. For example, Windows 2008 Datacenter is 1 license per processor while Windows 2012 Datacenter is 1 license for every 2 processors installed. The same applies to Windows Standard, Windows Standard 2008 is 1 license per device while Windows 2012 is 1 license for every 2 processors installed.
Movere can automatically link ESX and Hyper-V based virtual guests. While Hyper-V mappings can be extracted from the host, guest and the System Center management platform Virtual Machine Manager; ESX mappings can only be extracted from vCenter. When vCenter isn’t available, for example, when working with standalone ESX hosts, or when working with XenServer based guests, the guest to host mapping (for licensing purposes) needs to be completed manually.
Any unlinked virtual Windows Servers will appear in the unlinked section and will be colored blue, like all other virtual Windows Servers. To assign licenses manually, calculate the number of Windows Server licenses required and assign those to the necessary number of guests then mark any remaining guests as ‘Host Licensed’.
For example, the two unlinked virtual Windows Servers below, both are running on a single standalone ESX host. The first is running Windows Server 2008 Enterprise R2, while the second is running Windows Server 2012 Standard R2. A Windows Server 2012 Standard R2 license permits the use of two virtual guests on a licensed host. By assigning a 2012 Standard R2 license to the second guest then marking the first as Host Licensed, the license count on the Windows Summary page will only include 1 2012 Standard R2 license, but include the first guest in the Assigned License Count:
How do I confirm that every active Windows Server has been assigned a license?
On the ‘Summary Table’ view, within the ‘Windows’ section of the Movere website, the total number of licenses assigned can be seen, and exported, by version and edition. Above the assigned license counts are three control totals (refer below). The first, titled ‘Unassigned Server Count’ represents the number of active Windows Servers that have not yet been assigned a Windows Server license. The second, titled ‘Assigned Server Count’ represents the total number of active Windows Servers that have been assigned a license across all versions and editions. The number next to it, presented as a percentage, represents how many active Windows Server have been assigned a license as a percentage of the total active Windows Server population:
No further Windows Server license assignments are required once the percentage value next to the Assigned Server Count equals 100% and turns green:
