Comment 1 for bug 1815887

Actually, this seems to be more of a cosmic kvm32 type issue. It feels to me that when it's not booting, it's not even reaching grub actually. I was able to get the system booting by pressing 'shift' when kvm was starting - I was getting the grub boot-menu then and could successfully start the system. Then for the next few runs it was working out-of-the-box again. Later I got the same issue.

So it all feels like not related to the actual images, more like an issue in cosmic. Marking this as Incomplete until someone else also encounters this bug.
