Hmmm, I am not using the ISO, but rather the pre-installed cloudimg, and I am not so sure it is actually fixed. I just tried out the latest one, and can confirm the issue still persists with it:
https://cloud-images.ubuntu.com/focal/20200430.1/focal-server-cloudimg- amd64.img Here is the output from booting: [ 0.000000] Linux version 5.4.0-28-generic (buildd@lgw01-amd64-036) (gcc version 9.3.0 (Ubuntu 9.3.0-10ubuntu2)) #32-Ubuntu SMP Wed Apr 22 17:40:10 UTC 2020 (Ubuntu 5.4.0-28.32-generic 5.4.30) [ 0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-5.4.0-28-generic root=PARTUUID=be1f3b17-864d-49f8-8249-5fb0edc7e606 ro console=tty1 console=ttyS0 panic=-1 ...

But, because I am trying to configure the machine on the first boot using cloud-init NoCloud, it needs to actually work on the first boot. (Anyways, I think it's a moot point that first time booting should work.) In the above, the "panic=-1" followed by "Cannot open root device" indicates that there is still something amiss, at least with the cloudimg distribution. I can file a different ticket for cloudimg, if it would be more appropriate. Please advise.
