I started with a 64 bit version of Ubuntu 9.10 Karmic server edition. (using a micro instance on Amazon EC2, costing less than $0.01 per hour)
I added GNOME desktop to it and NX server.
I re-bundled the instance into a new AMI.
Now upon trying to start another instance of my freshly created AMI. I am unable to select a "micro"/cheap server format.
What have I done wrong? What triggered this limitation?
Is Amazon really smart enough to know which AMIs will work on which Servers? I had it running fine on a micro server while I re-bundled it..?
