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.

vSphere+Debian+KDE Plasma=Crash? (lemmy.world)

I needed a test VM at work the other day so I just went with Debian because why not, during the install I chose KDE plasma as the DE. I did nothing else with it after installing it and after leaving it alone for a while (somewhere between 20-60 minutes) the CPU useage shot up to the point vSphere sent out an alert and the VM was unresponsive (the web console just showed a blank console which I couldn't type in) It did this every time I booted the VM.

It seems to be the combination of vSphere Debian and KDE that causes this as I installed GNOME on the same VM and it was fine. I also created another Debian VM this time choosing GNOME during the install and that was also fine, until I installed KDE on that and then it started doing the same thing. I also created an Arch VM with KDE and that didn't have any issues.

Any idea why this combination causes issues? Journalctl output of the last boot from both Debian VMs below:

Original VM: https://text.is/032Z Secondary test VM: https://text.is/JR45

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
