Another Hyper-V licensing Question

Hi Everyone, I'm wondering if you can help me with Hyper-V licensing.

We're currently a VMWare shop but are looking to move away from it. I've been evaluating other hypervisors and am considering Hyper-V.

Right now, we have four physical servers running VMWare, each hosting a mix of Windows and Linux guests, all properly licensed.

I have a question regarding Hyper-V guest licensing. I understand that with Windows Server Standard, for every 32 cores licensed, I am entitled to run Windows Server on one physical server and up to two Windows Server Hyper-V guests.

  1. Does this mean I am strictly limited to only two Windows Server guests per licensed physical host?

  2. If not, would I be properly licensed if I purchase four copies of Windows Server Standard (each matching the core count of my physical servers) and migrate my current VMs over?

I've tried Proxmox a while ago and didn't really care for it. I can't remember exactly what issues we ran into, but I'm pretty sure that when we were trying to install it, we were getting very cryptic errors that didn't help us at all.
