Hi. I'm trying to create new KVM images using the --cpuset=auto option "to automatically determine the optimal cpu pinning using numa data" (from the man page). Problem is, I can't get this to work. The following always appears in my virt-install.log file when creating a new image: DEBUG (cli:833) Not setting cpuset: unsupported operand type(s) for *: 'NoneType' and 'int' I'm pretty sure I do have NUMA support properly configured and enabled and all of that, but unfortunately I don't have a great deal of experience with this stuff yet, so I can't guarantee that this isn't a user problem. I've primarily been following the advice in this guide: http://berrange.com/posts/2010/02/12/controlling-guest-cpu-numa-affinity-in-libvirt-with-qemu-kvm-xen/ When I run the nodeinfo and capabilities commands, I do get the appropriate NUM cell(s) and topology output as shown in his examples. Similarly for freecell, memtune, numatune, and all the other related commands I could find discussed on the internet. However, no matter what I try, I can't get virt-install to do the auto pinning for me. Is there anything else I could be missing? Some library or process dependency outside of libvirt that I'm missing? or could this be just a bug? Would appreciate any guidance in troubleshooting and identifying the problem. I've been working on this off-and-on for a couple nights now and have had no luck. Thanks. -- Jared
