Description swat30 2014-09-29 15:07:20 UTC 
Description of problem:
When booting cloud-init on F20, it can launch its init phase prior to networking being setup. This means that, while networking does work, cloud-init may never see it.


Version-Release number of selected component (if applicable):
v.0.7.2-10


How reproducible:
100%


Steps to Reproduce:
1. Boot fully updated F20 cloud image (cloud-init v.0.7.2-10, also tested 0.7.2-7)
2.
3.

Actual results:
Boot -

Additional info:
Fixed the problem by modifying cloud-init's systemd unit file.

Comment 1 Matthew Miller 2014-09-29 15:19:19 UTC 
Sadly, we don't have a good way of doing updates for the F20 cloud image. However, we _will_ have that for F21, and we can make sure this fix gets in there.

Ooops, pressed submit accidentally.

This affects the cloud-init package in general. This actually started happening to our image when we ran updates, which included the latest version of cloud-init.
Comment 4 Garrett Holmstrom 2015-02-23 22:29:09 UTC 
This should be fixed in cloud-init-0.7.6-3.fc22.  cloud-init-0.7.6-4.20140218bzr1060.fc22 will be pushed shortly with some major changes, so it may be worth testing against that instead.

Comment 6 Garrett Holmstrom 2015-02-23 22:40:08 UTC 
Update:  cloud-init-0.7.6-4.20140218bzr1060.fc22 isn't going to make it into F22 due to bug 1194577.  If you're testing rawhide it will appear there, but otherwise feel free to go ahead and test cloud-init-0.7.6-3.fc22.  Sorry about the confusion.
