Seven of fourteen models named Proxmox VE first on the direct prompt; zero named KVM. Proxmox VE was named by fourteen of the fourteen models and KVM by thirteen and Proxmox VE carries 76 labels and KVM 23, so the shares are not directly comparable.

Share is the count of first choices across the direct, paraphrase, budget and scale prompts over all fourteen models, for a mid-market B2B company; rank is within the category; every quote names the model and the prompt it came from. Both figures come from the server virtualization platforms page.

By framing
