That is what is throwing me off... When I edit the /etc/kernel/cmdline, it is empty! I do not even know where cat /proc/cmdline gets it's information.
Yes, I did copy/paste the line in the /etc/default/grub.

/proc/cmdline appears to come from your /etc/default/grub. I don't think you have to worry about /etc/kernel/cmdline as you system does not appear to use systemd-boot.
/proc/cmdline looks strange because of the wrong character that is not recognized as a double-quote and therefore the value in /etc/default/grub is being cut off at the first space.

I mean, crap, I am pretty sure it is using grub!! When I installed, I did not specify anything, unless it does not use grub by default... Maybe I am not.

Just change GRUB_CMDLINE_LINUX_DEFAULT=”quiet mitigations=off intel_iommu=on iommu=pt initcall_blacklist=sysfb_init pcie_acs_override=downstream,multifunction pci=nommconf” to GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on" (notice the different characters for double-quotes) and run update-grub (check for any warnings or error messages) and reboot before checking again with cat /proc/cmdline.

Holy F! That did it! Thank you, and yes I do indeed see your meaning of the quotes I had wrong. I thank you my friend.

Hey Guys! i have an very simliar problem

IOMMU is enabled but a get an error when i try to start a VM with a GPU Also on a DL380p G8



Im using the newest Bios that exists for that Server

 

[Adrian.Contigo]

nano /etc/default/grub

put

GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on,relax_rmrr iommu=pt intremap=no_x2apic_optout"

update-grub

Hello everyone

Just started setting up what santa bought me a nice DL360 G9 and what fixed it for me was
nano /etc/default/grub and update the line GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on"
Then do a grub-update && systemctl reboot and thadam! 132 IOMMU groups appeared

Then whenever i passtrough the P440AR Smart Array Raid Controller it didn't let me do that with vfio-pci 0000:03:00.0: DMAR: Device is ineligible for IOMMU domain attach due to platform RMRR requirement. Contact your platform vendor. to fix this i had to go in to BIOS and go to the P440ar board configuration from BIOS and disable Smart Memory something option then go ahead in the BIOS and there was one other thing i disabled, can't remember, i just looked for a similar option in the bios

HP Support thread on that helped me find the remaining information to make it work
