Sandboxing ComfyUI for AI agents in a VM with a single shared GPU remains unsolved on Windows
johnshedletsky · reddit · 2026-09-23
The author wants agents like Codex to create, edit, and run ComfyUI workflows without full machine access, so ComfyUI should live inside a VM. The blocker: paravirtualizing a single GPU to a guest isn't supported by mainstream Windows VM hosts like VMWare Workstation Pro, and the author avoids WSL. They're asking if anyone has gotten it working via AppSandbox or raw GPU-PV, acknowledging it's an uncommon, likely time-sink configuration.
