I have a question about licensing Windows Server with Hyper-V installed to host VMs, and consequently the licensing for the host and the guests.
I might be asking the most novice questions and not recognize it. I spent a long time in big IT, and my role was very narrow and did not cover Windows or servers. I've changed to something different with a much smaller organization, my role is less specific and is very broad. I am the only IT person at this organization at the moment. My former-workplace friends are all BIG IT, it seems they just true-up with MS enterprise licensing at the next cycle, they never have to make these MS licensing considerations beforehand.
I use ESXi 6.7 at home to host guests; Ubuntu hosting Docker, Ubuntu hosting Plex, a Windows testing VM, tinkering silos, etc.. I just can't figure out how to truly patch the ESX host. I've followed guides from others online and they have not been exactly the same as my system (for some reason). I asked a big IT ESX/vCenter systems admin friend to help me apply a patch to it, he had trouble navigating the manual process without the vCenter licensed host patching system/app (which apparently makes patching ESX hosts so much easier).
I, however, am not prepared to stake my job on my ability to patch ESXi for vulnerabilities in a production environment.
I want to purchase a Windows 2022 server to host multiple guest servers.
The server I am considering is to be 2 processor, 16 cores each; 32 cores total.
The guests (currently planned) would be the following OS and (minimum) Core requirement;
Windows Standard 2019, 12 cores (threads? I'm not sure with Hyper-V) to the guest
Windows standard 2019, 6 cores ....
Windows Standard 2022, 4 cores ....
Ubuntu LTS, 4 cores ....
If I use Windows Server standard, how many total core licenses do I need for both the host and the guests. Is it flexible, can I tear down the Ubuntu and allocate its cores to another existing server, or would those licenses be tied to that VM guest indefinitely?
HPE seems to tell me I need 6 total 16-core licenses? Nothing more, no 2 pack of Hyper-V licenses?
Do I also need to buy VM guests base Windows standard OS licenses?
Do I need to buy Hyper-V licenses?
Is this made so much simpler with Windows Data Center? If so, what do I purchase beside the DataCenter edition to be legal with MSFT while having MS guests in Hyper-V? If I'm understanding HPE's windows licensing page (https://techlibrary.hpe.com/us/en/enterprise/servers/licensing/index.aspx
), I just get 2 datacenter 16-core licenses and I'm licensed for all the windows standard guests my hardware can accommodate without more licensing to be purchased and I never have to think about anything besides capacity going forward? HPE's guide seems to make it soo simple in regards to DC edition, and therefore I'm not sure about it.
I don't know what I don't know. If there is something obviously missing, please let me know.
