AMD cpu (1600x) and I want to do nested VT so I can use hyper-v inside on vm. Already enabled necessary components in BIOS. Virtualbox allows me to in a test debian vm. How can I get this working on virt-manager? Currently doing pci passthrough for it too btw.
/etc/modprobe.d/vfio.conf
options vfio-pci ids=10de:1b81,10de:10f0
/etc/modprobe.d/kvm_amd.conf
options kvm_amd nested=1

EDIT:
Read:

2nd link I cannot do host-passthrough as it generates a boot loop in the vm and does first link mean I need to use WS because that's stupid as fuck.
EDIT1:
I FUCKING DID IT!! Jesus Christ that was cancer. With the files in my modprobe.d as said earlier, I just ran these two commands on this website and it lets me use!
