Al intentar encender una máquina vagrant o en Vbox nos da un fallo: alejandrogv@AlejandroGV:~/vagrant/servicios/dhcp$ vagrant up The provider 'virtualbox' that was requested to back the machine 'servidor' is reporting that it isn't usable on this system. The reason is shown below: VirtualBox is complaining that the kernel module is not loaded. Please run `VBoxManage --version` or open the VirtualBox GUI to see the error message which should contain instructions on how to fix this error.
