I have a Windows10 and a Windows11 machine (my new pc).
On both I have the latest version of VirtualBox 6.1.36. On both I have a ProxMox VM. Configuration is the same.
On W10 I can create and run a VM in Proxmox, on W11 I get the error wile starting a VM "KVM not installed or configured in the bios".
The new machine is an AMD5700-X, the old one an I7-6400.
Who is causing the error? W11?
And how can this be fixed?
Oh, and ProxMox is also the latest version 7.2-7

So you're doing nested virtualization? Windows > Virtualbox > Proxmox > something > another VM?jpflathead wrote:I have the latest version of VirtualBox 6.1.36. On both I have a ProxMox VM. Configuration is the same.

I'll wager that Hyper-V is enabled in 11. Do you see the green turtle in the status bar in the first layer Virtualbox VM? If so, see HMR3Init: Attempting fall back to NEM (Hyper-V is active).jpflathead wrote:on W11 I get the error wile starting a VM "KVM not installed or configured in the bios".

There is an extra step required in Win11 to completely disable Hyper-V.
In addition to all the stuff you have to disable in Win10, in Win11 you also have to disable core isolation memory integrity.
Settings > Privacy & security > Windows security > Device security > Core isolation details > Turn Memory integrity OFF

Turning Memory integrity off is mentioned in the linked tutorial.
