I'm sorry but I'll need more information to do any problem solving. I personally don't know vSphere but if you'll post the output of the logs I can help.
What is the purpose of this? Debian is stable but many users find the software to be outdated.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I've just edited the main post with links for the journalctl output. The purpose was just to test some network config, I managed to do what I needed anyway but I'm just curious as to why I had issues with these VMs!
It looks like it isn't happy. Usually this is the result of a hardware issue so keep an eye out for any other systems having issues. You may have a faulty ram.
Other than that, I would wait for someone who is better at KDE. The longs clearly show it trying to start and then failing.
Seconding the RAM issue possibility. If you can, shut down the host and run a memory test over a few days to see if it trips. Memory tests can take days to trip in some circumstances, in others, it’s immediate.
I hope its not a hardware issue, the 2 VMs were running on 2 separate hosts within the cluster so hopefully that's unlikely! Thanks for taking a look
Virtual video card settings?
I just left it as default which is 1 display and 8mb video memory
8MB?! That is abysmally low for KDE. Depending on the apps you're using, I'd recommend allocating at least 256MB, if you're going to use it for actual productivity tasks.
Edit: Here's a screenshot from nvtop showing my VRAM usage on KDE 5.27:
As you can see, Plasma alone is using 209MB, and Kwin 175MB, and this is with nothing but just Plasma and Konsole running on a very basic desktop (no fancy widgets, just one panel). Now this is at 2880x1800, so if your VM is running at a lower resolution you'd need lesser VRAM, but you can use that as a reference to see how much VRAM KDE really needs.
I just tried increasing it but the maximum I can set is 255 and that made no difference unfortunately. All the Windows VMs are also set at 8 and they don’t have any problems
