07:15 <shanduur[m]> Hi! Am I able to set `GRUB_CMDLINE_LINUX` anyhow in CoreOS? I want to be able to do PCIe pass through in the KubeVirt 🙂

07:41 <stephanepoq> are you looking for "--append-karg " ? https://coreos.github.io/coreos-installer/cmd/install/

07:49 <bgilbert> --append-karg only helps when running coreos-installer. it doesn't help with image-based use cases like kubevirt

07:50 <bgilbert> shanduur[m]: if you're using Fedora CoreOS and not with OKD, you can add kernel arguments with the kernel_arguments section in your Butane config

07:51 <bgilbert> shanduur[m]: if you're using OpenShift or OKD, there's a different mechanism you can use to add kernel arguments

07:52 <lucab> (depending on the kernel argument, there is also a good chance that it has a sysctl equivalent entry)

07:56 <bgilbert> dustymabe: add-override workflow fix in https://github.com/coreos/fedora-coreos-config/pull/1739

07:57 <shanduur[m]> I need to add `intel_iommu=on`

08:09 <lucab> shanduur: is FCOS the k8s host or the kubevirt guest?

08:19 <shanduur[m]> Host

08:22 <lucab> shanduur: and on which platform is it, or how do you provision the FCOS host?

08:25 <lucab> shanduur: generally speaking you are looking for https://docs.fedoraproject.org/en-US/fedora-coreos/kernel-args/#_modifying_kernel_arguments_via_ignition but there are there other options too depending on your specific/preferred flow

08:29 <shanduur[m]> Generally speaking, I will be migrating my home lab from PVE to FCOS (so bare metal deployment), as most of my workflow is on K8S. I am gathering knowledge about it now, as even I am running mostly containers, I want to add single Windows virtual machine, preferably with GPU passthrough.

12:33 <mgrundmann> how long will i be able to build with cosa v.0.13.0?

12:34 <mgrundmann> or asked another way are there features in v0.14.0 that are required for building current stable versions?

12:52 <dustymabe> ICYMI there is a fedora 36 release party going on now: https://hopin.com/events/fedora-linux-36-release-party/registration

13:01 <walters> mgrundmann: Have you considered *deriving* from FCOS rather than doing custom builds? See https://github.com/coreos/coreos-layering-examples

13:05 <dustymabe> mgrundmann: probably fine with v0.13.0 - but generally follow latest works best

13:05 <dustymabe> we'll be switching over to a Fedora 36 base soon

13:09 <mgrundmann> i will just stay on 0.13 as long as i still need the ostree tar

13:10 <mgrundmann> i will definetly check if i can do all customization using layering

15:12 <jlebon> could someone add an /approve to https://github.com/openshift/release/pull/28537 ?

15:12 <jlebon> otherwise the openshift cosa tests will keep using f35

15:14 <jlebon> dustymabe: thanks! i think i need someone from dptp now

16:59 <jlebon> dustymabe: ahhh nice. your comment rendered only after I added mine (https://github.com/coreos/fedora-coreos-tracker/issues/1175#issuecomment-1126259147)

16:59 <jlebon> should we mark them both as offtopic?

17:01 <jlebon> marked mine at least

17:01 <dustymabe> :)

18:09 <nemric> o/

18:09 <nemric> hi team :)

18:48 <dustymabe> needs review: https://github.com/coreos/fedora-coreos-config/pull/1740

18:51 <dustymabe> coreos-ci seems down - and I can't get to the OCP4 cluster

18:51 <dustymabe> i can get to the pipeline.. just FYI ^^

18:52 <jlebon> hmm, seems fine here

18:52 <dustymabe> jlebon: you can log in to https://console-openshift-console.apps.ocp.fedoraproject.org/ ?

18:53 <dustymabe> ok now it's working

18:53 <jlebon> test failed on ext.config.kdump.crash also in rerun

18:53 <dustymabe> weird

18:53 <jlebon> glitch in the matrix :)

18:53 <dustymabe> interesting
