I am facing problem in the log of the booted image. I booted 3 instances, all they took 3 different ips through dhcp. But only 1 is having ssh login and the cirros instance log is showing the message " network unreachable". I can ping or SSH the first instance but unable to login. It is the ubuntu image and I don't know the login username and password. The other two are not pinged or neither I can do SSH, although they have been alloted an ip by dhcp. I am not getting why it is happening so. Kindly reply

So we had the same issue, can you bundle a image without cloud-init & try starting it? It should work. This happens because your instance is not getting connected to the metadata server.

prebuilt ubuntu images most likely has cloud-init installed. The username could be ec-user or ubuntu, based on the version you are using. Often times, you are not allowed to log in using 'root' account. You are supposed to log in using a key-pair.

If you cannot ssh or ping to your instance, you may want to check whether security group has been set up properly.

Without further configuration details, there could be other reasons.
