...). But in the case that we still need a proxy for some reason on the host side, I think it would be better to have it in the same process where virtio-gpu is implemented. In crosvm's case it would be in a process separate from the main VMM, as device processes are isolated from each other with minijail (see https://chromium.googlesource.com/chromiumos/platform/crosvm/ ).
