  • Hi Sir,

    One standard server 2012R2 license may allow two VM instances running on it .

    If I recall it correctly , you may need to call Microsoft to get the key for VM activation (For details ,please contact with Microsoft ).

    As you mentioned , you have two server (I assume that will run windows server 2012R2 standard version) and you want to run 4 VMs on them .

    If it is the case , you may only need two license for two server if two VMs run on each physical server .

    But , if you want to build a cluster against two physical server , you may need to by 4 standard licenses , because it is possible to run 4 VMs on one physical server (If I recall it correctly ).

    Actually , license issue is out the scope of what we can support here .

    I'd still suggest you contact with Microsoft to get the accurate answer :

    Hope it is helpful to you .

    Best Regards,
