Qubes OS 4.0 has been released

Now that most VMs are fully virtualized now on 4.x, how much RAM and disk space do you need in order to have a usable system? The 'minimum requirements' they list of 4GB RAM and 32GB hdd wouldn't be enough to run more than a small handful of VMs.

It depends how many things you want to use concurrently. At Latacora some of us use Qubes to guarantee client separation, so lots of domains open and all of them running Slack, so, yeah, my machine has 32GB and that’s not a massive luxury.

With 8Gb of RAM I have been happily using Qubes 4 in my work workstation since rc2. I suggest to use the mirage firewall image [1] to save aound a Gb of RAM

The fedora 27 images can easily reach 5Gb of use under heavy load, but in gneneral I have pretty good performances and I usually have a couple of throwaway VMs and the main work VM running and dealing with web, co pilations of various sort and editing.

Why use Fedora for images and not something leaner, like Arch or Alpine Linux? (just examples, there are others too)
