Make sure you can SSH or remote desktop to your VM in your original vSphere environment. AWS at the destination does not support virtual console for accessing the VMs, so you need to make sure SSHD is configured and started.
For Windows ensure RDC is allowed through the firewall for all networks public and private.
You can also view syslog via the AWS Console (http://aws.amazon.com/console/) to conduct further investigation if necessary.
