[Bug 745930] Re: cloud-init timeout waiting for metadata service on EC2

[Scott Moser]

Well, if you lok at the attached console logs, you can see that cloud-
init is retrying.  In lucid, we retried 100 times with a increasing back
off, resulting in 17 minutes or so of trying.  The build scripts gave up
after 5 minutes.

In natty (both to reduce the pain if cloud-init was installed outside of
EC2, and because i had extreme amounts of data -- 2000+ instances that
waiting did not help), I reduced that timeout significantly, but made it
configurable in /etc/cloud/cloud.cfg.

So, at the point at which the build publishing scripts gave up, cloud-init had been re-trying (after network had already come up) for 2 minutes and 35 seconds.  In the natty test, it gave up after 2 minutes 45 seconds of trying.

If the metadata service isn't up 3 minutes after the instance is booted,
then there is a bug in the platform, expecting an instance to wait 3
minutes is not acceptable.
