Re: [CentOS] IOMMU and kernel (solved?)
I think i might have solve it. For some reason grub2-mkconfig doesnt work. (Have no idea why) I manage to solve it with grubby. sudo grubby --args="intel_iommu=on" --update-kernel=ALL For some reason it works. I dont know if it works if my kernel gets upgraded. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Hi, > I think i might have solve it. > > For some reason grub2-mkconfig doesnt work. (Have no idea why) Is this on CentOS 7? Well, yes, I remember that it didn't work for me when I installed new servers one or two years ago, that was with CentOS 7 and they were my first EFI installs. > > I manage to solve it with grubby. > > sudo grubby --args="intel_iommu=on" --update-kernel=ALL > > For some reason it works.

That way it has always worked for me. And I was a bis scared by the whole EFI, grub2 and everything around it because I felt I don't really understand how it all interacts in detail.

I dont know what happened either :-s Thanks On Fri, 2020-04-03 at 20:55 +0200, Simon Matter via CentOS wrote: > Hi, > > > I think i might have solve it. > > > > For some reason grub2-mkconfig doesnt work.
