I use Proxmox as a VDI server. I understand that this isn’t homelab territory, but selfhosted VDIs have proven exponentially more reliable and easier to manage than cloud based ones (after the initial PitA setup). Flawless copy/paste, screen resize, and most importantly, file transfers. When you connect to 12 different clients, each with a different set of security requirements, system hardening, monitoring, and VPN access, being able to console amd fully interact with a sandboxed desktop becomes priceless.
