Hi Hiroaki-1024,
In this case, we buy a 2 core subscription license for the first VM (1 year minimum according to the website), it will be deleted after testing.The second VM, we will buy a 2 core subscription license for the second VM (VM is 4 core)
To license individual VMs using the Per Core model, customers must purchase a core license for each v-core (or virtual processor, virtual CPU, virtual thread) allocated to the VM, subject to a four-core license minimum per VM.
Please refer to SQL Server 2019 licensing Guide for more details.
And for detailed information about the license issue, I suggest that you call 1-800-426-9400, Monday through Friday, 6:00 A.M. to 6:00 P.M. (Pacific Time) to speak directly to a Microsoft licensing specialist. For international customers, please use the https://www.microsoft.com/en-us/licensing/worldwide to find contact information in your locations. For Volume Licensing Service Support, please use the https://learn.microsoft.com/en-us/licensing/contact-us to contact information for your country.
