Solved LMDE7 run Virtualbox and Docker aside

[tinfoil-hat]

Hi, I have a relativley fresh install of LMDE7 and would like to run Docker alongside Virtualbox.
The steps to install Docker, I chose

Install Docker Engine on Debian

Learn how to install Docker Engine on Debian. These instructions cover the different installation methods, how to uninstall, and next steps.

docs.docker.com

I installed my Docker Containers via User, which is also in Docker Group.

Virtualbox is installed trough their APT Repo. it's Version 7.2.4 with Extention Pack. I already have added the user to vbox group.
I also tried to reboot and

sudo modprobe vboxdrv

I get the Error Message:

M Name: -Gateway-Xfce

AMD-V is being used by another hypervisor (VERR_SVM_IN_USE).
VirtualBox can't enable the AMD-V extension. Please disable the KVM kernel extension, recompile your kernel and reboot (VERR_SVM_IN_USE).
Result Code:
NS_ERROR_FAILURE (0x80004005)
Component:
ConsoleWrap
Interface:
IConsole {xxxxxx-xxxxxx-xxxxxx-xxxxxx}

If you need any information, let me know

I figured Unchecking

Enable Nested VT-x/AMD-V

in Virtualbox. solved it for me. Can you help me, enable nested AMD-V? I want to setup a Kubernetis Cluster next. Thanks

Running

lscpu | grep npt
lscpu | grep svm

Returns me the CPU Flags are available

Okay, I git the VM to start, but ONLY if I do the Following:

sudo modprobe -r kvm_amd
sudo modprobe -r kvm

And disable

Enable Nested VT-x/AMD-V

VM Name: -Gateway-Xfce

AMD-V is being used by another hypervisor (VERR_SVM_IN_USE).
VirtualBox can't enable the AMD-V extension. Please disable the KVM kernel extension, recompile your kernel and reboot (VERR_SVM_IN_USE).
Result Code:
NS_ERROR_FAILURE (0x80004005)
Component:
ConsoleWrap
Interface:
IConsole {XXXXXX-XXXXX-XXXXX-XXXXX-XXXXXXX}

I'd REALLY like to start the VM just as it's intended by clicking the "Start VM" button in Virtualbox

Turns out, I don't have to disable

Enable Nested VT-x/AMD-V

And everything works AFTER I execute

sudo modprobe -r kvm_amd
sudo modprobe -r kvm

lsmod | grep kvm

gives me

user@machine ~ [4]> lsmod | grep kvm
kvm_amd               217088  0
kvm                  1396736  1 kvm_amd
irqbypass              12288  1 kvm
ccp                   163840  1 kvm_amd

Maybe someone can help me to make it start without these commands

I was able to solve this by following:

Basicially I did

sudo rmmod kvm_amd
sudo rmmod kvm

Edit /etc/modprobe.d/blacklist

blacklist kvm_amd
blacklist kvm

and reboot
