Comment 2 for bug 1758409

Example run on a slower machine shows how nocloud-kvm does require more time:

So it seems I do need to add additional timing to the _wait_for_system for nocloud-kvm

ec2 uses the boto3 library to "wait for system" to start and lxd launches so fast it doesn't hit this condition.
