VirtualBox is ridiculously simple to set up and get virtual machines going. Shared folders, shared clipboard and much more are no issue.
But.
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?
works decently enough for me is https://virt-manager.org/ to deal with libvirt. its not quite as nice in some ways but way less resource intensive.
