Zero Trust VDI Without the Cloud Bill — Proxmox, Intel Arc Pro and Cloudflare Access

Part one: the architecture and the cost argument for replacing Azure Virtual Desktop with Proxmox, Intel Arc Pro SR-IOV and Cloudflare Access. On-prem OAuth for identity, browser-rendered RDP, a firewalled LXC tunnel on its own VLAN, KSM for memory density, and profiles on Ceph. The next post builds it.

One physical GPU split into virtual functions handed to separate Windows desktops

Licence-Free Windows VDI on Proxmox with an Intel Arc Pro B50 — and the Firmware Limit That Stopped It

Intel’s Arc Pro cards do SR-IOV natively, with no vGPU licence to buy — which makes a licence-free Windows VDI on Proxmox genuinely possible. The whole build on a B50, the Windows-first bootstrap problem, why the firmware caps it at two virtual functions, and how many each card in the B-series gives you.

PCIe Resizable BAR and Modern GPUs — Intel Arc, NVIDIA and AMD

Resizable BAR lets the CPU map a GPU’s whole framebuffer instead of peering at it through a 256MB window. Intel calls it required for Arc, NVIDIA enables it per game, AMD sells it as Smart Access Memory — and for AI work it changes the transfer, not the maths.
