But that's Linux
Honnest question: why is it Linux? I can't find relevant information on the matter. Every source point the fact that it's a bare metal hypervisor therefore not Linux but that's all. Could you enlighten me on the matter? Thanks in advance.
That was my first impression after a quick glance at it, since it listed Fedora, Debian and several other linux "flavors", plus wikipedia lists it as "OS Family: Linux".
Looking and paying proper attention, I see that it doesn't actually use the linux kernel, the OS just starts VMs for whatever applications you need. The dom0, the "main virtualized OS" and basically the bare minimum the user will interact with, runs Fedora, which is linux.
I see why I'd still call it linux, even if it's "not really" linux due to the kernel (Xen hypervisor) being something completely different, because all the user interaction goes through Fedora.
Thanks for the explanation, I understand now your point of view. It sums up on which layer we consider then. BTW qubes is a fantastic OS if you want isolation of information or privacy. One VM could serve for work, another for browsing, and eventually for privacy. Take care !
