[one-users] Problem Login/ssh into vm

I would like to note that when I added tty-linux - kvm from the
marketplace, created a simple template(same as the centOS), and run it, I
was able to login and use the vm. So I know the host works, and my problem
most likely is in the way ssh works from the controller to vm's...

Also noteworthy, I cannot ping the vm's from the controller...only from the
host. Im not sure this is correct or not.
