When the `machine start` command is executed, Podman automatically retrieves the current host's `*_PROXY` environment variable and assigns it directly to the virtual machine in QEMU. However, most `*_PROXY` variables are set with `127.0.0.1` or `localhost`, such as `127.0.0.1:8888`. This causes failures in network-related operations within the virtual machine due to incorrect proxy settings.
