It sounds like the user account was successfully created. Check if SSH is listening on both the public and private addresses:
netstat -l -n | grep ':22'

If it isn't listening on the public address, then there's probably a problem with /etc/ssh/external_sshd_config or /etc/init.d/ext_sshd. Check the end of external_sshd_config. There should be 2 lines containing the correct username and public IP address for the reservation:

ListenAddress <public IP>
AllowUsers <username>

Also, check if you can SSH from the management node to the VM using the username/password for the reservation on either the VM's public or private address.

Thank you all, the issue was the image groups and computer groups weren't
mapped together and I have fixed it now.
I am able to make a reservation now but the issue which I am now facing is
that when I try to connect to the remote machine through the credentials got
from the web front end, the login fails because of user authentication
issues. however using the same user id and password I am able to login
through the VM console. . Both the ssh daemons are running and node is
accessible.I suspect some configuration issues with the ssh. any help or

Thanks and Regards

I am facing few issues when trying to make a new reservation. even though
have computers available loaded with the desired image, I still get "There
are currently no computers available that can run the application you
selected". Is there any selection /setting which I am missing.
