Hello David. First of all, thank you for the guide. Very helpful! Second, i have an issue with the nested virtualization, maybe you can help me. So in windows 10 last ver 1909, i have installed the latest virtualbox ver of 6.1.2 r135662. Activated the nested virtualization as per your instructions, installed Ubuntu 18.04 as the first VM. And inside Ubuntu i need to install a minikube with all its dependencies(kvm or virtualbox as driver; docker; kubectl). The issue is that after all is installed successfully, when i start either the KVM as a test or type in "minikube start", the VM freezes completely. Only a restart or shutdown can revive it. Please advise!
This video was super helpful in getting the nested process up and running on the VirtualBox. Now I can continue to build out my Pen testing lab. Thank you Cheers Alex
Actually, I've had nested VMs on my ThinkPad for about 11 years. I have a ThinkPad E520, which I bought almost 12 years ago and run openSuSE on. Shortly after I got it, I installed VirtualBox. I created VMs for Windows 7 (later updated to W10), Windows 98 and OS/2 Warp 4. One thing that OS/2 had was virtual machines for DOS and Windows 3.x, going back to OS/2 version 2 in 1992. You could even create a VM for CP/M-86! Warp 4 includes Windows 3.1. So, when I run the OS/2 VM and then open Windows, I have nested VMs. For fun, I set up 4 desktops in Linux, 1 each for Linux, Windows 10, Windows 98 and Warp 4 with Windows 3.1, all running at the same time on my ThinkPad! Before OS/2, IBM was really big with VMs on the "big iron" mainframes. BTW, back in the late 90s I used to do 3rd level OS/2 support at IBM Canada. That's also where I started with Linux, as we were encouraged to work with it on company time. I'd even get packs of Linux disto CDs in my mail slot occasionally.
Thanks David for making our life more easier. Ive tried it at end of 2019, but unfortunately i was unable to checked the box, it was greyed out. Now i know how to enable it. God bless you David.
David a billion times thanx for the CCNA packet tracer in Udemy, Man that gives me a good a clear view about things I found hard. Sorry it is a different topic. P.s you should have done more " no ip domain lookup" hahaha just joking THANX AGAIN MAN
I think just rolling up a vmware linux Ubuntu machine, installing gns3 and the appropriate IOS Virl works the best. No other vms needed and a decent pc with 16GB runs it just fine. Seems the easiest, but its nice to see virtualbox getting caught up.
i couldn't run NETSTED VIRTUALIZATION DUE AN ERROR,i had to uncheck it ! but the problem is whenever i run the machine of GNS3 VM the default setting changes the machine settings and recheck "activate nested virtualization" well ,so i had to uncheck it manually ,start the machine and paused it ! ,then save settings,then run gns3 to not load default setting ,unfortunately ,it works to run VM on gns3 but without nested functionality.i want to keep it disabled but everytime the default settings are loaded !!! i tried to attribute the VBoxManger.exe as readonly but it doesn't work ! thank you ,
hi david its doesnt work for me it gave me this error when i click start : Cannot enable nested VT-x/AMD-V without nested-paging and unresricted guest execution! (VERR_CPUM_INVALID_HWVIRT_CONFIG).
I use WSL 2 in my windows 10. And I can't start the GNS3 VM, they say like this "gns3 windows VBoxManage.exe: error: Cannot enable nested VT-x/AMD-V without nested-paging and unresricted guest execution!" is this because I use WSL 2?
Hi David, I have a question. How are you managing to run CiscoIOSV15.7(3)M3 on Virtualbox GNS3 VM, every time I attempt to run it there it crashes it. I have also checked the GNS3 Documentation on Cisco VIRL and it says it doesn't support virtual box. My configurations are exactly the same as yours on Virtualbox for the GNS3 VM, and I can run other machines on it but any QEMU VM templates don't seem to work. Thank you.
i followed all the steps to allow nested visualization on intel,I get the below error C:\Program Files\Oracle\VirtualBox>VBoxManage.exe modifyvm "GNS3 VM" --nested-hw-virt on VBoxManage.exe: error: The machine is not mutable (state is Saved) VBoxManage.exe: error: Details: code VBOX_E_INVALID_VM_STATE (0x80bb0002), component SessionMachine, interface IMachine, callee IUnknown VBoxManage.exe: error: Context: "SetCPUProperty(CPUPropertyType_HWVirt, ValueUnion.f)" at line 851 of file VBoxManageModifyVM.cpp. Pls how can I fix it
So this is the better free option? Less hassle to set up vs Vmware workstation player as you need to do some modifications to get that working properly. Also with Intel support now how is it speed wise do you notice a difference between using it and Vmware
Tested for EVE-NG: kvm module is enabled but heavy node like a CSR crashes... So IMHO, the VBOX nested virtualization is still incomplete and unstable... :-(
One downside of Virtualbox 6.1 that i've found is it is not supported by current 2.2.6 version of Vagrant. So if your using Vagrant for the dev you might want to wait with VBox upgrade till 2.2.7 comes out. Great video :-)
Hello David, I've successfully enabled nested virtualization on my Mac in VirtualBox, but I'm still encountering issues. My GNS VM is reporting "KVM: FALSE," and I'm still receiving an error when trying to import the CSR1000V appliance in GNS3. The error message states, "The selected server does not support KVM. A Linux server or the GNS3 VM running in VMware is required." Can you help me troubleshoot this problem?
I can't get the virtual box move beyond importing the gns3vm.ovf. Once the file is opened, the whole screen is full and when I reduce the virtualbox to see the "continue tab" to hit it, it does not do anything. I am running Mac Sierra 10.13.6. Any suggestion or help is much appreciated. Thanks
I'm trying to run Windows XP mode using MS Virtual PC (microsoft official software for XP support) inside Windows 7 running in a VBox on a mac. I've followed this tutorial and I'm looking at coreinfo's output and VMX "Supports Intel hardware-assisted virtualization" is still disabled. My application (Windows XP mode) is not working, and it fails with a very useless error message "Installation failed, Please try again". Google research tells me it's probably due to this VMX problem stated above. Any idea ?
Thank you again David for your precious work! So now… in your opinion, without filters ☺️, which is your advice about VM support to use on OSX? For your labs, what platform do you advise ? VMWARE or even VirtualBox? I tried the large BGP labs, but with Virtualbox I am experienced slowness… Again thank you!!!

How come i just update vbox today and the latest version I've got was 6.0.16 r135674(Qt5.6.2)??, You already have v6.1 since last year!. Anyway, nested virtualization is available in my version as well, need to activate it through the cmd line through.
If you go to the main virtualbox.org site you will be able to download 6.1 - are you using Intel or AMD? Nested VTx has been available in AMD since December 2017.

Good idea Augustin
@@davidbombal Actually I did try to integrate, but then I can't get it running, virtual box vm is kicking but not going up green inside the GUI.
How come i just update vbox today and the latest version I've got was 6.0.16 r135674(Qt5.6.2)??, You already have v6.1 since last year!. Anyway, nested virtualization is available in my version as well, need to activate it through the cmd line through.
If you go to the main virtualbox.org site you will be able to download 6.1 - are you using Intel or AMD? Nested VTx has been available in AMD since December 2017.
can you give the commands for a Mac please?
"Virtualization core: Support for nested hardware-virtualization on Intel CPUs (starting with 5th generation Core i, codename Broadwell), so far tested only with guest running VirtualBox" :-\
Yeah, I wasn't able to get a windows server VM to enable its virutalisation
