Re: [Xen-devel] remus error

Sounds like your kernel is missing netlink support. I don't remember
the exact config option required, but if 'tc qdisc' (from the iproute
package) works, that probably means you've enabled the right
option. As I think I mentioned before, turning on something like Token
Bucket Filter ought to drag in the necessary dependencies.
