Hello windowsguy. Firstly, your command to generate the hashed password is wrong, as you are specifying the salt and not the password. See [1].
To hash 1234asdf execute: $ mkpasswd --method=SHA-512 --rounds=4096 1234asdf $6$rounds=4096$MJ9ozPaNS2HWVZcg$rwThVdxIm33BegbW2f2gNLq3JXzej5URpdOxPKna5uSI6K/opwxdZ317vgM1btgcys89ZDu520aglKOSvjT3Z0 or $ mkpasswd --method=SHA-512 --rounds=4096 -S mycoolsalt 1234asdf $6$rounds=4096$mycoolsalt$hNRWY61tyEOF.15a9a2q8PZ5Z/vFmBcRTDJrPzrl5ZK/iVPLQjCvEKWUmjSkqE1EyIRLgaYLYY1Y6BomzTIV./ Secondly, a password field which starts with an exclamation mark in /etc/shadow means that the password is locked, see [2]. This probably happened because you tried to log in using 1234asdf as the password a lot of times. I am going to mark this bug as invalid. Please, try with one of those hashed passwords and comment here if you find any additional problem.

Also 'ubuntu' can login. After provisioning is complete and the VM reboots, I cannot login as 'ubuntu'. I log in as root and find that now a '!' was prefixed to password hash in /etc/shadow: ubuntu:!$6$rounds=4096$1.... If I remove that '!', I can login as the ubuntu user. I tried surrounding the password with single and double quotes, no difference. Initially it's provisioned correctly, so it's something that injects that '!' after that.
