Drivers for recent homelab NICs in XCP-ng 8.2

stormi

@Andrew It's not planned. See https://xcp-ng.org/forum/post/61142.

So, can anyone test the intel-e1000e-alt and r8125-module drivers on real hardware?

@stormi
I can test the r8125 driver, but I already use the @Andrew drivers from his pre-renamed ISO. What do I need to do to “uninstall” his and switch to the testing?

stormi

@ajpri1998 Yes, you need to make sure the kernel package is up to date (for the display fixes, if you need them), boot the main kernel, remove Andrew's drivers, and install our package instead.

This may help: https://xcp-ng.org/forum/post/61095

@stormi
Thank you! I think I got it working. Previously had version 9.009. Now:

@ajpri1998 Is this after a reboot, to make sure the new driver is loaded?

ajpri1998

@stormi yes, this is after a reboot.

So far my R8125 is still working.

Also my Dell Optiplex 5040 does have a I219-V. It did work out of the box without issues with a iso downloaded last week. Does the alt driver add any additional features/functionality?

stormi

@ajpri1998 I don't know. I assumed @Andrew built version 3.8.7 for a reason since we already had version 3.8.4 by default in 8.2.

He wrote it adds many device IDs, so I believe that if your NIC was already working, the updated driver is not necessary for you.

However, your feedback would remain useful: if the NIC works with the updated driver, it helps validating the build. Then you can remove it and go back to the main driver to avoid unnecessary customizations.

I moved the drivers RPMs mentioned above to the xcp-ng-updates repository, so it's not necessary anymore to add --enablerepo=xcp-ng-testing to install them.

Being in xcp-ng-updates doesn't mean they will get installed automatically next time you update. No dependency will pull them on your 8.2 hosts unless you explicitly ask to install them, with yum install.

@stormi
Do you mean that if I install i225 driver, next time I do “yum update” within 8.2, I loose the driver (leaving host without network connection), or do you mean the driver will not be added when I in the future do an upgrade to 8.3 (or for instance 8.2.x)? As these drives are in 8.3, that should not cause a problem, correct?

stormi

I only mean that, if you are on XCP-ng 8.2 and haven't installed the drivers, updating the hosts will not force-install the drivers to your hosts. In other words, it's not because a package is made available in the updates repository that it is necessarily selected by RPM dependencies to update all XCP-ng 8.2 hosts that install official updates.

But if you choose to install such packages, then they will remain (at least until a full upgrade using the installation ISO).

Thanks!

Hi,

I'm new to xcp-ng and coming back to linux after about a 20 years break (so my knowledge is either very recent, or very old).

I have a new fanless computer with intel i226 chips, I'm trying to install xcp-ng on it but I can't find out how.

I have the 8.2.1 iso on a bootable usb, already used it to install on 2 older hosts.
I have downloaded the rpm and added it to the Packages directory but the installer refuses to go because I have no ethernet cards.
So I guess I need to somehow add the driver with the F9 menu on the first screen, but I have no clue how. When I try it say that no drivers were detected.

I've also tried extracting the ko file from the rpm and put it on the usb, but it is not automatically loaded and not detected by the F9 menu, so I guess it's in wrong location

Is there a guide somewhere on how to do that ?

Andrew

@nhurion Use the new 8.3 version. It has newer drivers.

nhurion

@Andrew
Thanks, I know this is an option.
However, I already have 2 hosts with 8.2.1 that I do not want to upgrade yet.
And even if I install another iso, I would still like to know how to be able to load a driver or add a driver to an existing iso.

Andrew

@nhurion If you boot 8.3 does everything work correctly? Just as a test.

The official 8.2 boot ISO does not have i225/i226 drivers. I did build an unofficial one that has drivers...

nhurion

@Andrew
Yes, installing from 8.3-apha2 does work.

Now if there is an option to load an additional driver, I guess there is a way to get that driver added.
How do I do that ?

Andrew

@nhurion You can give my Test 3 ISO a try. I have not updated it in a few months so it does need updates. Don't use the ALT kernel...

I would recommend against going for a custom solution: you might have more issues than going to XCP-ng 8.3. Despite it's alpha, it's already very stable. And a first beta version is around the corner!
