hi:
when I use openstack devstack to test QOS, wired phenomenon appeared,
I set qos ingress rule in tapB, but when I reboot tapA, the ingress rule of tapB automatically removed, but the egress rule is still exist.
Test enviroment:
Linux: ubuntu 14.04.1 LTS
kernel: 3.13.0-32-generic
libvirt: 1.2.2
openstack: havana
1. use nova to create vm A and vm B. for the configuration of the libvirt xml, see the last paragraph in the end.
2. use tc cmd to create qos rule for vm A and vm B
tc qdisc add dev tap3d0d2c4a-0b ingress //vmA
tc qdisc add dev tap896d5066-69 ingress //vmB
3. then use cmd
"sudo virsh destory 142a08db-6e25-4a03-be13-7073104b0745 " to first shutdown vm1
then I see ingress rule of vmB disappeared :(
configurations:
