VM use rights
Certain licensing rules allow for covering not only the physical host but also associated virtual machines. With VM use rights, each licensed installation entitles the use of a fixed or an unlimited number of virtual instances of the application.
VM use rights are registered when adding a license purchase and can only be registered for licenses with assignment type Computer/datacenter. Note that VM use rights will only be applied to associated virtual machines if the physical host is fully compliant.
Snow License Manager 9.2 introduces a feature that takes Microsoft Windows Server licensing rules into account: when a Windows Server license is added, the VM use rights are fixed, that is, automatically applied in accordance with Microsoft licensing rules.
If Windows Server Standard is used, the fixed VM use right is two VMs per each fully licensed host.
If Windows Server Datacenter is used, the fixed VM use right is an unlimited number of VMs per each fully licensed host.
A computer is assigned four licenses. VM use rights allow each assigned license to be used on three virtual instances. This means that the four assigned licenses can cover 12 virtual machines.
From one license purchase, Server A is assigned eight licenses and Server B is assigned four licenses. VM use rights allow each assigned license to be used on one virtual instance per server.
Server A has 16 associated virtual machines. The VM use rights for Server A are changed so that eight specific virtual machines are assigned a license each. The remaining ones need to be covered by another license purchase. The changed VM use rights for Server A overrides the original VM use rights.
The VM use rights for Server B are not changed and will continue to be dynamically assigned as needed. The four assigned licenses are still allowed to be used on four virtual instances.
