[SOLVED] VBoxModifyVM Problem

Hello friend!

earlier I installed virtualbox on my computer, but I found a problem that enable nested VT-X/AMD-V is greyed on the option, so i enabled SVM option on the bios and checked with command :

LC_ALL=C lscpu | grep Virtualization

and the result is :

Virtualization: AMD-V

and then i forced the vm to enable the option with :

VBoxManage modifyvm “Arch 2” --nested-hw-virt on

and then the output :

VBoxManage modifyvm “Arch 2” --nested-hw-virt on
WARNING: The vboxdrv kernel module is not loaded. Either there is no module
available for the current kernel (5.10.15-1-MANJARO) or it failed to
load. Please recompile the kernel module and install it by

       sudo /sbin/vboxconfig

     You will not be able to start VMs until this problem is fixed.

VBoxManage: error: Could not find a registered machine named ‘Arch 2’
VBoxManage: error: Details: code VBOX_E_OBJECT_NOT_FOUND (0x80bb0001), component VirtualBoxWrap, interface IVirtualBox, callee nsISupports
VBoxManage: error: Context: “FindMachine(Bstr(a->argv[0]).raw(), machine.asOutParam())” at line 546 of file VBoxManageModifyVM.cpp

Can someone explain what is this?
Processor : AMD Ryzen 5 3400G
GPU : Vega 11
Kernel : 5.10.15-1
DE : KDE 5.20.5

Is that module loaded?
Apparently not.

Hi @AtapFedora,

According to a quick Google search that lead me to this page the headers for your kernel version should be installed.

Thanks for the reply my friend!

it turned out that after several experiments, the result was that I entered the wrong virtualbox name! My virtualbox name is “Arch2” but I give the command by entering the name “Arch 2”
