Platform emulation does not work with Apple Virtualization Framework on macOS 15.7.2

[jpelkonen]

Description

Since upgrade to macOS 15.7.2 on apple silicon, I get exec format error when trying to run linux/amd64 or linux/i386 images when Apple Virtualization Framework is selected. Switching to Docker VMM seems to fix the issue. Colleague on macOS 15.7.1 does not have the same issue.

docker run --platform linux/amd64  -it ubuntu:24.04 bash
Unable to find image 'ubuntu:24.04' locally
24.04: Pulling from library/ubuntu

Status: Downloaded newer image for ubuntu:24.04
exec /usr/bin/bash: exec format error

Reproduce

1. Turn Apple Virtualization Framework on
2. run: docker run --platform linux/amd64 -it ubuntu:24.04 bash

Expected behavior

Should launch emulated bash
