[Xen-users] Scheduling traffic based on Vif interfaces on xen dom0 using DRR

[rp-user <pinaroland@xxxxxxxxx>]

Hi
i am using tc tools on dom0 to schedule traffic that comes from
different guests using Deficit Round Robin scheduling algorithm. Here
is my scenario:

eth0------| bridge |--------------+----- vif1.0   domU 1
                 |                     |
                 |                     +----- vif2.0 domU 2
               dom0                |
                                       +----- vif3.0 domU 3
                                       |
                                       + ...  ...     ...  ...  ...
                                       |
                                       +------ vif10.0 domU 10

And i use this config:

#1
tc add qdisc add dev eth0 handle 1 root drr

#2
tc class add dev eth0 parent 1: classid1:1 drr quantum 3000
tc class add dev eth0 parent 1: classid1:2 drr quantum 1500
tc class add dev eth0 parent 1: classid1:3 drr quantum 3000
...        ...       ...       ....       ...    ....       ....
....  ....   ....   ..

tc class add dev eth0 parent 1: classid1:10 drr quantum 3000

#3
iptables -t mangle -A FORWARD -m physdev --physdev-in vif1.0 -j MARK
--set-mark 1
iptables -t mangle -A FORWARD -m physdev --physdev-in vif2.0 -j MARK
--set-mark 2
iptables -t mangle -A FORWARD -m physdev --physdev-in vif3.0 -j MARK
--set-mark 3
...        ...       ...       ....       ...    ....       ....
....  ....   ....   ..
iptables -t mangle -A FORWARD -m physdev --physdev-in vif10.0 -j MARK
--set-mark 10

#4
tc filter add dev eth0 protocol ip parent 1: handle 2 fw flowid 1:1
tc filter add dev eth0 protocol ip parent 1: handle 3 fw flowid 1:2
tc filter add dev eth0 protocol ip parent 1: handle 4 fw flowid 1:3
...        ...       ...       ....       ...    ....       ....
....  ....   ....   ..
tc filter add dev eth0 protocol ip parent 1: handle 11 fw flowid 1:10

############

the first problem is that as i just enter the first command to create
a root drr qdisc the dom0 and other guest can not be reachable outside
eth0, while inside interdomain communication is ok.

Which is  the problem?
Thanks
