Hi.
Im trying to set intel_iommu=on on kernel parameters at grub but for
some reason it doesnt work.
I edit /etc/default/grub file and i add the parameter.
then i run grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg and then i
reboot.
when i run virt-host-validate i get
QEMU: Checking if IOMMU is enabled by kernel: WARN (IOMMU appears to be
disabled in kernel. Add intel_iommu=on to kernel cmdline arguments)
when i edit the grub menu durring boot and i put intel_iommu=on and the
i run again virt-host-validate i get
QEMU: Checking if IOMMU is enabled by kernel: PASS
any ideas?
I tried editing other variables like GRUB_TIMEOUT and it seems to me
that changes are applied.
Thanks in advance
