[ec2] Bug... somewhere :-P

[Guillem Cantallops Ramis]

Hi All,

Sometimes (this has happened in roughly half of my tests) I cannot SSH 
to the Ubuntu instances I launch on EC2 and my user-data scripts aren't 
executed. The only solution is terminating the rogue instances and 
trying again. It works, eventually, but this is both annoying and expensive.

I'm attaching two logs I got from the AWS Console, showing a good boot 
and a bad one, I'm sure you will spot the differences at the end. 
Fortunately there are clues there.

I would be very happy to use official Ubuntu images for several demos, 
running our own software (a grid middleware) in EBS volumes and 
launching it from a user-data script. But if this fails half of the 
time, I can't!

Any help will be appreciated. Regards,
