virtio-gpu

Helix gives each coding agent its own desktop. On a Mac that desktop is not its own GPU. One QEMU VM. One physical GPU. Each agent gets a virtual output through virtio-gpu. Helix’s own blog says one desktop is fine, two are fine, and deadlocks show up at 4+ sessions on that GPU. On Linux plus NVIDIA it is different: real per-session containers and hardware encode. Isolated screen. Shared silicon. At least on Apple Silicon.

Helix为每个编码代理分配独立桌面，但Mac上共享物理GPU可能导致4个以上会话死锁，Linux+NVIDIA实现更彻底的资源隔离。
