VirtualBox nested Intel virtualization is here!

VirtualBox now supports nested virtualization on Intel processors. In the past, this was only available on AMD processors. This opens up a whole range of applications with VirtualBox: You can run your GNS3 topologies on VirtualBox, you can nest hypervisors and have some fun. Great to see VirtualBox support for nested virtualization now available on both Intel and AMD processors.
These are the commands I used to enable nested Virtualization via the CLI:
Open a CMD prompt:
==================
Use these commands:
cd C:\Program Files\Oracle\VirtualBox
VBoxManage.exe list vms
VBoxManage.exe modifyvm "GNS3 VM" --nested-hw-virt on

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!

[@James_Knott]

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.

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 :-)

[@davidbombal]

Great information. Thank you for sharing!

[@kaizoku47]

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 ,

Thanks David! Very helpful video! Similar issue could happen for vmware users. The physical PC is definitely support VT-x but still, cannot run such function for VMs. Have you made a video for VMware already? :)

[@mikerfields]

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

Still early days. In my brief tests I found that VMware works better. We need more people to test and give feedback.

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?

[@davidbombal]

Yes. Nested virtualization doesn't work when WSL 2 is enabled currently. Hopefully they can solve this in future.

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 ?

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?

Hi David. I have a problem with VM Workstation and with VirtualBox. I am using AMD Ryzen 5. have Virtualization enable. When i boot a GNS3 on Virtual box a cant enable KVM, i check and mark VTX/AMD-V but still shoes me KVM false. on VM Workstation when i boot GNS3 i have a message that its not support on this platform. Other issue i have with EVE-NG, on VM Workstation a have the same problem, sa,e message when i start to boot a EVE-NG and the problem on Virtual box with EVE-NG is that when i start the noods they are shoodown after couple of second. I was your student on Udemy, CCNA course, a pass the CCNA and CCNP as well but i need to try to fix this ptoblem vith virtualization because i countinue learning with Palo Alto , Check Point and FTD Firewalls and i cant do the labs without EVE-NG or GNS3. please, some advice to fix the issues. Thanks

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.

Alright, after putting back the settings to > --nested-hw-virt off and powering off the host the VM started working again. I did import the GNS3 VM and ran the command and the command did enable the KVM hypervisor to work, the GNS3 VM now can run in my Linux host, but I am not sure why you would want to do that if you have already GNS3 running in the host > in my case Linux.
