Anything you save to a VM stays there even if you shut the VM off (unlike a live USB). It runs an operating system and has its own files. VM: A virtual machine is just a program that thinks it’s a real computer. In addition, not every system needs a lot of RAM to run what it needs to run. That’s not to say that every system will speed up if you upgrade RAM, because there are other components which could slow down a system (e.g., a fragmented hard drive, a really inefficient piece of programming). Upgrading RAM often speeds up computers because it’s a common system bottleneck that is, the system can only go as fast as its slowest component, and that’s often RAM. RAM is like your computer’s short-term memory. RAM: aka “memory,” this isn’t the same thing as storage. Windows is one Mac OS X is one Linux is one. If you’re well-grounded in the basics, the tl drs are in red. I’m not going to assume you know everything, so I’m going to cover a lot of really basic info in this article. Not everything you do to make these things run well is terribly obvious, so I’m covering it for you. I think it was successful, since when I run lsmod | grep vboxguest, I get the output: vboxguest 45056 0, which I gather means that the Virtualbox kernel module is installed and that the guest additions have been installed correctly.In this post, I’ll give you what will hopefully be a shortcut around all the nonsense I went through trying to make a Linux (specifically: Lubuntu) VM to play with. I know that this way this should work is by installing guest additions, and I've done this. When I go to full screen mode, the "Ubuntu screen" is still windowed and very small. I've set up the virtual machine all fine, but would like to view it in full screen mode, but I can't do this. I'm running an Ubuntu 20.04 virtual machine on Virtualbox. I know this is a fairly commonly asked question, but I've followed the other solutions and none of them seem to solve my problem.
