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?
You can specify the virtualization engine in VirtualBox, including KVM.
A couple of easy virtualization tools that allow you to create VMs in a few clicks are Gnome Boxes and QuickEmu, which leverages Qemu and KVM
Good tip. Thanks.
