Re: [vfio-users] Any help to finish my qemu ovmf script please ?

Save xml to some location other than /etc/libvirt/.. and do all the commenting/uncommenting there. virsh define /path/to/vm.xml to use modified xml. You indeed are going the wrong direction. Even if libvirt does not expose some functionality via xml it is also possible to pass raw qemu flags. I needed it only for vga passtrhough, using efi firmware thats no longer needed (although libvirt might expose -vga via xml now, i dont know). Also unsure whats not working for you but even virt-manager exposes functionality to pass entire pci devices to vm. Be it sata or usb or whatever. If it is not working for you maybe correct solution would be figuring out pci passthrough and not reverting to a shellscript.

Libvirt doesn't allow me to comment in and out things during vm runtime.
Bash script is for me much more clearer than an xml file, since i'm almost done i might aswell finish it.

Being able to pass my 4to disk, my usb controller (required for plug and play, also i want to be able to use my usb key on win10 and not have glitchy audio with my usb headset), and having a net bridge would be a huge step forward.
Also i don't have enough configuration possibilities with virt-manager
libvirt xml is much more powerful than the features exposed through virt-manager:

I'd suggest trying to do what you want through libvirt before trying to re-invent the wheel.  This is what libvirt is meant to do after all.
