I figure machined terminates because it's idle. This would suggest the registration of the machine didn't work, or that the unit that libvirt registered went away. Right after the machine was started, but before machined dies, do you see the machine's scope registered in "systemctl list-units"? Do you see the machine show up in "machinectl"'s output?
