KVM/QEMU/Virt-Manager is a hypervisor and a good alternative to Virtualbox. Performance should be better using this combination since KVM is built into the Linux kernel itself. And it's not difficult to convert your existing Virtualbox VM's over to Virt-Manager.
SOME COMMANDS I USED IN THIS VIDEO:
LC_ALL=C lscpu | grep Virtualization
yay -S qemu virt-manager ebtables
sudo systemctl enable libvirtd
sudo systemctl start libvirtd
sudo systemctl status libvirtd
sudo usermod -G libvirt -a dt
sudo qemu-img convert -f vdi -O qcow2 Ubuntu\ 20.04.vdi /var/lib/libvirt/images/ubuntu-20-04.qcow2
