I recently found out about a Linux Distro named Q4OS and I wanted to test out their claim that it only requires 256 MB of ram when using the trinity desktop environment. However, when I used the live cd in virt-manager with 256 MB or ram, it just kernel panicked at boot. So I then tried it with 512 MB of ram. In addition to some issues that are not present when you are using at least 1 GB of ram, such as “sudo apt update” causing the entire VM to become unresponsive, I noticed that it seemed to actually use anywhere between 290 MB to 370 MB of ram when the only thing running was the process viewer (which is htop).

Obviously, this is still very low for a modern Linux distro but I was wondering how accurate VMs are for testing ram usage.

And, yes I know that it would be pretty much useless on a PC that only had 256 MB of ram even if it did work. I’m actually checking the ram usage because there is a possibility that I may be using a very old computer of mine that only has 1 GB of ram at some point in the future. So I’m just testing it and eventually other distros out to to see which one I’m going to end up using (assuming I do actually end up even using that computer).

Edit: I just tried the 32-bit version in virt-manager and htop stated it was only using 232 MB of ram, which means that their claim was right and that I might have been using the wrong version.

Edit 2: I just tried installing the 64-bit version in virt-manager and htop stated that it was using about 350 MB of ram, so I don’t know if installing it actually made a difference.

    Are you conflating a claim that the system requires less than 256mb or ram with a claim that it can run on hardware with only 256mb of ram?

    Maybe those two claims are not the same?

      In what situation would those two not be the same?

      On their website, it states that the minimum requirements for the OS are 256 MB, that’s what I was going off of. I even mentioned in my post that even if it was installable on a computer with 256 MB of ram that it would be pretty much useless.

      Also, I just tested the 32-bit version and, like what another user stated, it does use less than 256 MB of ram, which means that their claim is right.
