GNS3 VM "KVM Support Available: False" on VirtualBox Windows 11

Question

Dear all Microsoft Agents,

I have computer and laptop, my computer uses windows 10 and my laptop uses windows 11. Both installed GNS3 and VirtualBox. On my computer the KVM on GNS3 VM VirtualBox is True, while on my laptop is False. I have enabling virtualization on BIOS, disabling Hyper-V on windows feature and enabling nested VT-x/AMD-V on VirtualBox but the KVM still False. I wonder there's problem with windows 11 while windows 10 can run it. Hopefully, there is a solution that can solve this.

Hi Mohammed Aryo,

Welcome to Microsoft Community.

Disabling the Hyper-V feature may not have completely blocked Hyper-V related services.

The content in the following links described a similar issue.
