As the title mentions I d like to pass through a sata/usb3 controller so before I (if ever) manage to passthrough the gpu I need first to pass through the controller upon which is the ssd i have dedicated for the VM.
The controller is an Asmedia with an isolated iommu group and need it only for the VM.
Can anyone tell me in which files do I have to put the pci id’s in order to pass it / exclude it for the host OS etc?
In a guide I tried for the gpu he used the files
/etc/default/grub
/etc/initramfs-tools/modules
/etc/modules
/etc/modprobe.d/amdgpu.conf (probably not in this one but do i need to make an identical for the controller?)
/etc/modprobe.d/vfio_pci.conf
/etc/modprobe.d/kvm.conf (probably not this one too because its just for the installation of Win)
/etc/apparmor.d/abstractions/libvirt-qemu (for the permitions of apparmor)
If you follow a guide meant for a GPU you can simply substitute the address for the controller where you’d put the GPU? It all kinda depends on the distro and if you’re planning on doing a GPU in the end anyway is there any harm in using one?
Passing through a gpu doesnt necessary means that same steps need to be followed for each device. As you see above some new files were created upon gpu pass through such as
/etc/modprobe.d/amdgpu.conf (do I need to create a new file like Asmedia.conf and what procedure is going to call that file?)
What about here
/etc/modprobe.d/vfio_pci.conf
or
/etc/modprobe.d/kvm.conf
or apparmor?
Also why should I put a line inside the /etc/default/grub since it was only to enable the iommu just once (of course this is jsut my thought doesnt mean that I am right thats why I need the verification from someone of what I need to do exactly)
I dont know about you but it isnt as easy for me .
Kinda why I recommended following a guide if you don’t know what’s what and are just getting your feet wet. Specifically, the guide I linked uses a method that is device agnostic. There’s no modifying module options either. There are other guides too. If you want to use a specific distro you might be able to find a matching guide. Ask questions on it if something isn’t clear.
In that case there shouldn’t be too much differences I think? I applied the guide to Pop Os 18.04 w/kernel 4.15, which is ubuntu based. If anything it should be easier as Debian uses grub out of the box doesn’t it?
I think yes but I cant figure out if its grub (has been depricated) or grub2. I was searching yesterday now that you reminded me for the command to check the version of the boot loader but then again it wasnt clear to which it was using
