Title:
KVM Instance booting from volume stacktraces
Status in cloud-init:
Invalid
Status in cloud-init package in Ubuntu:

Status in linux package in Ubuntu:

Bug description:
I've booted two instances from the same backing image (http://cloud-
images.ubuntu.com/trusty/current/trusty-server-cloudimg-
amd64-disk1.img), one using locally attached storage for the boot
volume, one using a Cinder volume. The instance booted from cinder
volume shows a cloud-init trace in the console log, while the local
instance works correctly.
Instance booted from volume:
Cloud-init v. 0.7.5 running 'init' at Wed, 27 Jun 2018 09:43:10 +0000. Up
15.61 seconds.
