Booting ubuntu-20.04-live-server-amd64.iso on VMware virtual machine fails

Solution 1:

Just finished installing a bunch of these, and had an error that occured in all due to missing UUIDs of disk being exposed to the VM.

To fix, I had to

  • open vSphere
  • power down the VM (cannot do this if powered on)
  • edit the VM (Right click, Edit Settings...)
  • go to the VM Options tab from the top
  • open Advanced section
  • Click Edit Configuration in "Configuration parameters"
  • click on "Add configuration params"
  • add option with disk.EnableUUID as name and TRUE as value
  • restart the machine
  • Ok, save etc and restart

Solution 2:

Rather than mounting the .iso to the VM on the console from your machine, upload the .iso as a Content Library Object. Then mount the .iso to the VM you are creating via the newly created CLO. You will still receive the message above of Plymouth: Refused to connect etc., however it will finish its check much more rapidly.

For me, the check went from 10-15 minutes (or about what you appear to be experiencing) down to ~10 seconds.
