I tested this on Ubuntu 5.4.0-1133 directly in focal. As well as a Noble system container under that focal
root@f-vm:~# uname -a Linux f-vm 5.4.0-1133-kvm #142-Ubuntu SMP Fri May 2 19:51:44 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux root@f-vm:~# numactl --membind=0 echo success success root@n-2ndlvl:~# numactl --membind=0 echo success setting membind: Invalid argument So it might be that noble container (with the new code) on an older kernel (without the MPOL_PREFERRED_MANY) is the way to go. Ready for a backport + PPA + tests. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2136104 Title: numactl gives "Invalid argument" error when trying to set a node for memory using membind To manage notifications about this bug go to: https://bugs.launchpad.net/appmajix/+bug/2136104/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
