time.sleep(2)
newinstance.instances[0].add_tag('Name',instancename)

print "Waiting for public_dns_name..."
counter = 0
while counter < 70:
    time.sleep(1)
    conn.close()
    conn = boto.ec2.connection.EC2Connection(ec2auth.access_key,ec2auth.private_key)
    startedinstance = conn.get_all_instances(instance_ids=str(newinstance.instances[0].id))[0]
    counter = counter + 1
    if str(startedinstance.instances[0].state) == "running":
        break
    if counter == 69:
        print "Timed out waiting for instance to start."
print "Added: " + startedinstance.instances[0].tags['Name'] + " " + startedinstance.instances[0].public_dns_name
