Used to use Qubes OS, quit because I could not figure out how to move files / share files between VMs securely / easily.
Want to try again, but a little concerned that AWS seems to have moved away from Xen.
One of the points that look like a plus to me, was that Qubes OS was based on a widely used, battle tested hypervisor, Xen.
The biggest cloud platforms looks like AWS, Google Cloud Platform (GCP), and Microsoft Azure. I should check if what hypervisors they are using.
