[StarCluster] building an ami corrupts the original reference machine?

[Jennifer Staab]

I can't attest to the behavior of StarCluster regarding AMI creation 
because I usually do my AMI creation from AWS console. I can say that in 
the past I had SSH go down if I created an AMI of a running instance.  
Luckily after the AMI was completed and I reboot a few times I got SSH 
functionality back without having to mount my EBS backed instance to 
another running instance to restore SSH functionality.  After that 
experience I just stop the instance prior to making an AMI.  This of 
course only works on EBS backed instances where the stopping them 
doesn't result in termination -- also stopping will dump all that you 
have stored in instance storage.  If rebooting the instance doesn't work 
you can look here <http://alestic.com/2011/02/ec2-fix-ebs-root> for 
directions on mounting to another running instance to restore functionality.

Good Luck!
