Thank you for your answer.
Does OVS respect the queues issued with tc? I have not tested it yet,
but pfifo_fast could be in effect if type= is omitted.

I want to create QoS flows.
The examples on the Internet that I can find realize this by using
the type=linux-htb in the creation, like the command below:
ovs-vsctl set port p1p1 qos=@newqos -- --id=@newqos create qos
type=linux-htb other-config:max-rate=1000000000
queues:1=@eth04queue1 queues:2=@eth04queue2 -- --id=@eth04queue1
create queue other-config:max-rate=10000000 -- --id=@eth04queue2
create queue other-config:max-rate=20000000
This will create a HTB scheduler as can be seen from this:
5: p1p1: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500 qdisc
htb state UP mode DEFAULT group default qlen 1000
link/ether 68:05:ca:39:da:bc brd ff:ff:ff:ff:ff:ff
What other schedulers can I use for type? I want to use the
pfifo_fast scheduler, but when I enter the first command with
type=pfifo_fast or type=linux-pfifo_fast the result from ip link
show will not change.
This leads me to believe that type=pfifo_fast or linux-pfifo_fast
has no effect.
On some Linux versions pfifo_fast is the default queueing mechanism,
some newer versions use mq, but that might not be relevant here.
Is it documented somewhere what strings I can use for those mechanisms?
Documentation is at 'man ovs-vswitchd.conf.db'. Search for "QoS TABLE"
