I am working on a server running ESXi 6.7. I have a VM which has a Linux guest. I installed the Linux guest in text mode with no graphics. After the installation and post-install configuration was completed, I created a snapshot. I then installed KDE Plasma and configured it which worked wonderfully. When I was finished, I created a second snapshot.
At some point an hour or so later, I wanted to go back to the VM as it was in the first snapshot, when only the base Linux was installed with no graphical components. I shut down the VM and created a third snapshot so I could go back to the current state of the VM, then I restored the 1st snapshot. The GUI reported success and showed the YOU ARE HERE indicator at the 1st snapshot - the one when there was only a basic text mode installation on the VM. However, when I booted it up, the state was unchanged. It was still in full graphics mode. Also, to verify it had not somehow reverted to a different snapshot I verified that the log files contained entries from before I shut it down to start the whole reverting process so the state was, in fact, unchanged.
Why does this happen? From reading, it seems I could clone one of the snapshots but I don't actually need it that bad. However, I will want to get the snapshots function working going forward. What should I do.
Thank you for your time.
