Basically license it again to cover each pair of additional VMs or purchase a DataCenter license instead. More details below.
- Each host needs to be licensed.
- A minimum of 8 core licenses is required for each physical processor and a minimum of 16 core licenses is required for each server.
Core licenses are sold in packs of two. - Standard Edition provides rights for up to 2 Operating System Environments or Windows Servers containers with Hyper-V isolation when all physical cores in the server are licensed. For each additional 1 or 2 VMs, all the physical cores in the server must be licensed again.
- DataCenter Edition provides rights for unlimited Operating System Environments or Windows Servers containers with Hyper-V isolation when all physical cores in the server are licensed.
