[virt-tools-list] virt-install cpuset=auto error

[Jared]

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.
