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.

That might be fun then.
QEMU can be as simple as this:
Here you are first creating a disk image with the format qcow2 and maximum 20G capacity. This is a QEMU disk image format that will take up very little space and grow as you use up the VM disk.
This will start a VM with 256MB of RAM, the alpine.iso image in its virtual CD/DVD slot, and the disk image you just created as a virtual drive. This will come with networking enabled by default, so you'll have internet access from within the VM.
It should now drop you into the Alpine installation. Alpine is very lightweight so it's great for experimenting, but you could do virtually the exact same for most other flavors of Linux and BSD images out there.
Once you are done installing, you can power off the VM and then start it with this:
That's basically the same without the
-cdromargument, this time with 2GB of RAM. I find QEMU a delight to play with because it has sane defaults like that. Hope you have fun too!Thank you for such a detailed breakdown! I'll give all of this a go over the weekend.
