Hi @rhythmic-painter-76998, if you enabled the pcidevices addon, there will be a

harvester-pcidevices-controller

DaemonSet running on the cluster. You can check the Pod’s log by executing

kubectl -n harvester-system logs harvester-pcidevices-controller-xxxxx

to see if there’s any error message. And if it’s possible, please grab a support bundle file and post it here. We can help look into it. Thanks

Thank you! I quickly scan for similar issues, and it turns out there’s one https://github.com/harvester/harvester/issues/3630. But that seems to be resolved already … cc @great-bear-19718 @limited-breakfast-50094

but my pcicontroller is running image: rancher/harvester-pcidevices:v0.2.4, the code mentioned (i.e.

they should be in same iommu group.. but i see iommu group is not loaded for some reason in device status
