Public bug reported: LXD image provided in the ubuntu: remotes do not contain BPF kernel module.
BPF module is present in the stock linux-generic versions of the kernel package but *-kvm kernel does not appear to be built with it -- this is a request for its inclusion. Repro: --- 1. Deploy a 20.04 or 22.04 release image (ubuntu:focal or ubuntu:jammy should suffice) VM on LXD (not container) 2. Observe uname -r to see that the -kvm variant of the ubuntu kernel is running 3. Check to see if BPFilter module is available: # find /lib/modules/$(uname -r)/ -type f -name '*bpfilter.ko' There are use cases where the BPF module is still used and it may be a while before users are able to transition to 24.04+ which I understand transitions to using the generic kernel. ** Affects: linux-meta-kvm (Ubuntu) Importance: Undecided Status: New ** Affects: linux-meta-kvm (Ubuntu Focal) Importance: Undecided Status: New ** Affects: linux-meta-kvm (Ubuntu Jammy) Importance: Undecided Status: New ** Also affects: linux-meta-kvm (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: linux-meta-kvm (Ubuntu Jammy) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-meta-kvm in Ubuntu. https://bugs.launchpad.net/bugs/2054155 Title: Add BPF kernel module to 20.04 and 22.04 images Status in linux-meta-kvm package in Ubuntu: New Status in linux-meta-kvm source package in Focal: New Status in linux-meta-kvm source package in Jammy: New Bug description: LXD image provided in the ubuntu: remotes do not contain BPF kernel module.
