Configuring Intel GVT-g on Proxmox VE: Sharing Your iGPU Across Multiple VMs Simultaneously

Put your existing Intel iGPU to work by splitting it into multiple virtual vGPUs with GVT-g, running simultaneously across multiple VMs in Proxmox VE. This guide covers the full process: enabling kernel parameters, creating mediated devices, assigning them to VMs, and real-world monitoring — the result: Jellyfin transcodes 4K H.265 at just 15% CPU instead of 100%.
