Fail to load i915 on guest OS (Ubuntu 23.10 aka 6.5.0-44-generic) "err -2"

[sheetsg77]

I'm receiving an error after installing dkms per readme (no errors on compile by the way), updating grub and then initramfs. Then adding VF to hardware and restarting.

Output from dkms status

greg@ub-mantic:~$ dkms status
i915-sriov-dkms/2024.07.19, 6.5.0-44-generic, x86_64: installed

Haven't tested it in Ubuntu 23.04 but Ubuntu 22.04 with kernel 6.5.0-44-generic. Try apt install linux-modules-extra-6.5.0-44-generic and reboot.

Thanks - that worked. Now onto testing Jellyfin I'm also going to experiment with Ubuntu 24.10 (6.8 kernel), I'll let you know - Reply to this email directly, view it on GitHub<#183 (comment)>, or unsubscribe<https://github.com/notifications/unsubscribe-auth/ADTDXH3UARG5EQJQ36P2Q2DZNLPV5AVCNFSM6AAAAABLGETCNCVHI2DSMVQWIX3LMV43OSLTON2WKQ3PNVWWK3TUHMZDENBRGMYTMMZRHE>.

resolved by pasbec suggestion to apt install linux-modules-extra-6.5.0-44-generic and then reboot.
