I haven’t yet set up proxmox, but yeah, I think hyper-V would work well in a small to medium windows shop.

The negatives I found probably don’t apply

• for large installations, it never scaled as well as VMware. We saved millions on licenses when we switched, but had to buy a lot more hardware. In particular we were doing software QA where we needed many VMs but they didn’t need much resources, and hyper-v just couldn’t scale in that direction. More standard use cases probably won’t have this problem, plus this was 4 years ago so I don’t know if anything has changed
• for special case installations, hyper-v was a horrible experience on my laptop. I had the resources, but couldn’t pass through usb devices, and it kept messing up my networking.
