-## PLAIN QEMU WITHOUT LIBVIRT
-### WORK IN PROGRESS
-### ONLY USE THIS IF YOU KNOW WHAT YOU'RE DOING
-
-I don't use VMs so I didn't test it extensively. \
-Only tested it for if it actually passes GPU, and it seems to do the job. \
-You need to figure out missing pieces on your own.
-
-Passthrough can be done with plain qemu without using libvirt. \
-The general idea of using plain qemu is to avoid managing libvirt configurations and rather use a single portable script.
-
-Stuffs taken from YuriAlek's [script](https://gitlab.com/YuriAlek/vfio/-/blob/master/scripts/windows-basic.sh).
-
-Create disk image with QEMU.
-```sh
-qemu-img create -f raw Disk.img 256G
-```
-
-The script should be run as superuser. \
-Run with nohup to make the script run even after terminal closes.
-```sh
-doas nohup ./passthrough.sh > ~/qemu.log 2>&1
-```
-
-Use ``lspci -nn`` command to get device ids.
