GPU Passthrough using IOMMU

[CisntSharp]

So im attempting to setup a VM on my debian(buster) linux distro currently when attempting to isolate my nvidia gtx 760

so ive currently followed these steps

i ran "lspci -nnk" anf got my gpus device ids being

video: 10de:1187

audio: 10de:0e0a

i then went to the file

"/etc/initramfs-tools/modules"

and appended this to the end of it

"vfio_pci ids=10de:1187,10de:0e0a" ( i later appended it to /etc/default/grub resulting in it looking like this "GRUB_CMDLINE_LINUX_DEFAULT="quiet nouvea.modeset=0 iommu=pt intel_iommu=on vfio-pci.ids=10de:1187,10de:0e0a""

then i ran

"update-initramfs -u"

after all this the gpu is still being taken control of by "nouveau" and i cant figure out how to resolve it

Did you update grub? check the grub config file somewhere in /boot

I'm not sure what order you ran what commands in but it's likely that for some reason GRUB's configuration didn't get updated earlier.
