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?
Yea, the installation isn’t too difficult. Looking at my groups as well I think it’s only the
libvirtgroup that you have to add a user to for KVM/QEMU with Virt-Manager, but the same could be said for VirtualBox as I believe you have to still add the user to thevboxusersgroup if you were to install it instead.
