Functions

func Launch

func Launch() error

Launch a control process around qemu VM manager.

This function is invoked from 'talosctl qemu-launch' hidden command and wraps starting, controlling 'qemu' VM process.

Launch restarts VM forever until control process is stopped itself with a signal.

Process is expected to receive configuration on stdin. Current working directory should be cluster state directory, process output should be redirected to the logfile in state directory.

When signals SIGINT, SIGTERM are received, control process stops qemu and exits.
