… virtual machines where you only have to select which accompanying image of Arch / Tumbleweed / Ubuntu / Fedora you want to try.
In addition, the combination of a very stable base system (say, Debian or SuSE Leap) with a fast-moving, bleeading edge virtualized system (say, SuSE Tumbleweed, Arch or Guix) on top can be surprisingly useful. And because small virtual machines, when not running, are nothing else than files on your computer, you can have many versions of them, alter things, try stuff out, then delete it and go back to the tidy original state.
now that i think of it, it’s more than a supplement because it makes the software defined networking MUCH MORE intuitive if you’re using KVM/QEMU.
Yeah. Makes it also easy to share files between host and VM via NFS, which can be handy when running cooperating desktop systems.
that too; i guess it’s wrong to call it a supplement when it unifies all these systems that seem disperate if you don’t already know the kvm/qemu ecosystem.
