Hi,
does anybody has the same issue?
I can´t start any virtual machine anymore. Evan new ones. And if i change the virtual machine setting to one CPU, PAE/NX and Netsted VT disabled i am getting the same failure.
I disabled SVM Mode in Bios and tried it with one CPU Core and changed it to SVM Mode enabled again. Nothing changed.
Thx

Disabling SVM mode will kill VirtualBox completely. Turn it back on.

Your original problem is because you have Hyper-v installed, or something that implies Hyper-v.

Thx, Hyper-V was disabled in the Windows feature menu. I have disabled it again via powershell and cmd.
