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 :(
Interesting. With the latest libvirt I am unable to reproduce - there's
a check and QoS is cleared out only if set in domain XML. Since your
domain XML lacks it, I guess it's either already fixed or not libvirt fault.
