How does Qubes OS work?

1- You said VMs are already preinstalled. What does it mean? When you install the Qubes OS, then by default some VMs already there? Which OSes?

Yes. Here is my super-short introduction to Qubes explaining which VMs are preinstalled. They are based on Fedora by default.

2- You said No, and you don’t have to do it on Qubes (although some people do it). You use VMs as security domains,… so, Is the Qubes OS a hardened OS? If yes, then why install a virtual machine?

Qubes OS is hardened by the fact that you run everything in VMs, which are isolated from each other by hardware virtualization.

@Hack3rcon

3- How Qubes OS use both of the Debian and Fedora operating systems simultaneously?

You can have several VMs, some of which are based on Debian and some on Fedora.

4- Are templates complete operating systems?

Yes.

@Hack3rcon

Do you mean AdminVM is Qubes OS itself?

Qubes is Xen, and it runs minimized Fedora in a special, privileged VM (dom0, adminVM), which is only used to manage other VMs.

@Hack3rcon

For example, when you install a Linux distribution, then some applications like the Internet browser, LibreOffice, Media player and etc. are part of the distribution.

On Qubes, you have all these in VMs.
