Hello Scott, or anyone else affected, Accepted cloud-utils into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/cloud- utils/0.27-0ubuntu25 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-xenial to verification-done-xenial. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-xenial. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .

[Bug 1741300] Re: mount-image-callback fails on qcow image on xenial
** Description changed:
+ === Begin SRU Template ===
+ [Impact]
+ mount-image-callback fails to mount images that are qcow2 formatted.
+
+ This function in mount-image-callback works in other Ubuntu releases
+ but not on xenial. The function does succeed some times, but is
+ brittle.
+
+ The fix applied is also applied upstream, and consists mainly of adding
+
+ blockdev --rereadpt /dev/nbdX
+ udevadm settle
+
+ where 'nbdX' is the device that mount-image-callback has set up to
+ point to the file that is to be mounted.
+
+ These above added function should not be harmful in any case.
+
+ [Test Case]
+ In a fresh install:
+
+ $ sudo apt-get update -q && sudo apt-get install -qy cloud-image-utils
+
+ $
url=http://cloud-images.ubuntu.com/xenial/current/xenial-server-cloudimg-amd64-disk1.img
+ $ wget "$url" -O xenial-server-cloudimg-amd64-disk1.img
+ $ cp -a xenial-server-cloudimg-amd64-disk1.img disk.img
+
+ $ sudo mount-image-callback -v disk.img true
+ waiting on pidfile for /dev/nbd0 in /sys/block/nbd0/pid
+ connected disk.img (qcow2) to /dev/nbd0. waiting for device.
+
+ [Regression Potential]
+ The regression potential stems from additional udev events
+ caused by calling blockdev --rereadpt.
+
+ udev events should not cause unwanted side effects, but could.
+
+ [Other Info]
+
+ === End SRU Template ===

On xenial only:
$ wget
http://cloud-images.ubuntu.com/xenial/current/xenial-server-cloudimg-amd64-disk1.img

artful and bionic are 'fix-released' as some magic in udev/systemd makes it work.
