VirtualBox is ridiculously simple to set up and get virtual machines going. Shared folders, shared clipboard and much more are no issue.

It eats resources. The installed virtual machines (VM) run relatively slow. What have you found to be feature comparable - and most importantly more resource-efficient - alternatives for running VMs under Linux?
Containers don’t emulate anything. They have an OS installed within them. Typically you use Alpine Linux which super minimalistic and lightweight.
yes, valid point, thank you for the correction
