Re: [Xen-devel] remus error

[Ashish Bijlani <ashish.bijlani@xxxxxxxxx>]

"tc qdisc" works fine I guess:

qdisc pfifo_fast 0: dev peth0 root bands 3 priomap  1 2 2 2 1 2 0 0 1
1 1 1 1 1 1 1
qdisc pfifo_fast 0: dev imq0 root bands 3 priomap  1 2 2 2 1 2 0 0 1 1
1 1 1 1 1 1
qdisc pfifo_fast 0: dev vif3.0 root bands 3 priomap  1 2 2 2 1 2 0 0 1
1 1 1 1 1 1 1

what could be missing?

Thanks,
Ashish
