gampel	yuli: raofei will help you with the setup	06:19
gampel	yuli: do you have a setup running with DVR enabled ?	06:19
gampel	raofei: are we building the br-ex on the compute node as well in the devstack script	06:20
gampel	yuli: ??	06:20
raofei	yes. actually, br-ex is created by df-controller currently.	06:20
raofei	devstack script just set the neutron.conf for external network items.	06:21
gampel	we need documentation for the end user how to add the physical nic to br-ex	06:21
gampel	it can be in a different patch on our wiki on how to set up distributed DNAT	06:22
raofei	ok. I think it user use devstack, then I will add a item in local.conf to assign physical nic to connect external network	06:22
raofei	yes. I will do it.	06:22
*** yuli_s has joined #openstack-dragonflow		06:23
yuli_s	Hello all	06:23
gampel	I am not sure we need the physical nic in the devsatck but we need guide for the admin how to set it up	06:23
raofei	At the beginning, i think br-ex and physical nic is managed by adminstrator	06:23
raofei	OK	06:23
gampel	yuli: raofei will help you with the setup whats the status of the testing ?	06:24
raofei	The behaviour is similar with the original l3 feature, adminstrator manage the br-ex and physical network.	06:24
yuli_s	my computer had powered off	06:25
raofei	@Yuli, I send a message to you this morning	06:25
yuli_s	raofei, gmail ?	06:25
raofei	Before creating fip, you need 1)set the gateway into router. eg, neutron router-gateway-set router-demo ext-net; 2) then create fip. eg, neutron floatingip-create ext-net;	06:25
raofei	just irc channel	06:26
yuli_s	my computer was closed	06:26
yuli_s	please send it to stremovsky@gmail.com	06:27
raofei	when you physical service is recovery, please try to do it.	06:27
raofei	this is same with centralized router.	06:27
yuli_s	raofei, why public network is not created automatically now ?	06:28
* yuli_s running stack		06:29
raofei	I need to verify it on my setup. it's created on my setup	06:29
yuli_s	I am doing stack every day	06:30
yuli_s	it just happened yesterday for the first time,	06:31
gsagie	raofei: maybe send yuli_s your local.conf	06:31
gsagie	so you can compare, maybe the problem is there	06:31
raofei	Maybe it's because we disabled the l3-agent. but I have to check it again.	06:31
yuli_s	I run stack several times yesterday and it was heppening all the time	06:31
yuli_s	ok, give me your email,	06:32
yuli_s	i will send you the file	06:32
gsagie	also maybe its a different devstack version you are trying with	06:32
gsagie	raofei: you work with master devstack/master neutron?	06:32
raofei	yes. I use the master devstack	06:32
raofei	but I haven't update it for 1 month.	06:33
yuli_s	you better update	06:34
raofei	I think if devstack cannot create external network, it will not impact our test. we can create network manually	06:34
raofei	sure, I will update it and test it today.	06:34
yuli_s	raofei, we have done that yesterday	06:35
raofei	yes, and you found fip cannot be created successfully.	06:36
yuli_s	btw	06:36
yuli_s	what is your email,	06:36
raofei	I checked your router configuration, it's because you didn't set the gateway.	06:36
yuli_s	I will send you my local.conf	06:36
raofei	milo.raofei@huawei.com	06:37
raofei	OK, I will check it on my setup now	06:37
yuli_s	done	06:38
yuli_s	u use ubuntu ?	06:39
raofei	ok, we are same	06:39
yuli_s	if yes, remove the python api code	06:40
yuli_s	before running stack	06:40
yuli_s	in /usr/local/lib/python2.7/dist-packages/python_*	06:40
yuli_s	in /usr/local/lib/python2.7/dist-packages/neutron*	06:40
yuli_s	in /usr/local/lib/python2.7/dist-packages/oslo*	06:41
yuli_s	when running "clean.sh" it is not removed	06:41
raofei	do you mean need to clear the setup?	06:42
raofei	yes, I always clear the setup by clean.sh	06:42
yuli_s	yes, it just do not removes the library code	06:42
yuli_s	as a result, new version might not work, so you remove the libraries code too,	06:43
yuli_s	before running stack.sh	06:43
yuli_s	and you can also run "git pull" in devstack installation dir	06:44
yuli_s	to get the latest version	06:44
yuli_s	ok, I got the stack up & running	06:45
openstackgerrit	yuan wei proposed openstack/dragonflow: Impliment security group fullstack and ut cases https://review.openstack.org/299105	06:46
gsagie	yuli_s: i dont think its related to the libs	06:47
yuli_s	yes, just he used an old version of code,	06:47
yuli_s	i had to remove old libs a week ago to be able to run stack	06:48
gsagie	raofei: i will try to run your patch as well, can you please send me your local.conf	06:48
gsagie	that you were able to work with	06:48
gsagie	to gal.sagie@gmail.com	06:48
gsagie	and what other actions are you doing beside the stack? do you also connect the physical NIC to br-ex and change routing?	06:49
yuli_s	again, I have a problem like yesterday : "Port to be associated" is empty !	06:57
yuli_s	ok, found a problem this time !	07:02
openstackgerrit	Nguyen Hung Phuong proposed openstack/dragonflow: Fix typos in Dragonflow files https://review.openstack.org/299167	07:06
yuli_s	from vm I can ping private gw	07:08
yuli_s	no ping to 8.8.8.8	07:08
yuli_s	raofei, any ideas ?\	07:14
raofei	sorry, just see the message. I will send the email	07:16
raofei	@Eran, yuli I sent a mail to you.	07:23
raofei	@Eran, I create the br-ex and add a physical nic into br-ex(such as eth1). When df-controller get restart, it will create patch ports to connect br-int and br-tun.	07:25
raofei	@Yuli, do you add the private network into router?	07:26
yuli_s	yes	07:28
yuli_s	i am checking now the tcpdump	07:32
yuli_s	i see ping on tap device	07:32
yuli_s	10:32:52.980181 IP 10.0.0.3 > google-public-dns-a.google.com: ICMP echo request, id 22529, seq 98, length 64	07:33
yuli_s	nothing on br-ex	07:34
yuli_s	sudo tcpdump -i br-ex ICMP	07:34
yuli_s	sudo tcpdump -i br-ex icmp	07:34
raofei	do you test on single node or mutiple node?	07:35
yuli_s	single box	07:35
raofei	if single node, you need disable q-l3	07:35
raofei	please dump flow of br-int	07:36
yuli_s	#enable_service q-l3	07:36
raofei	show me the dump-flows	07:36
yuli_s	sending it to your email	07:36
raofei	where is you external gateway?	07:37
yuli_s	good question	07:38
yuli_s	let me check	07:38
raofei	The problem is df controller cannot learn the arp from gateway.	07:38
yuli_s	yes	07:39
yuli_s	i do not remember that I specified anywhere the external gw	07:40
yuli_s	today	07:40
yuli_s	i have this in local.config: PUBLIC_NETWORK_GATEWAY=10.100.100.8	07:40
yuli_s	how to make sure it is used ?	07:41
raofei	the external gateway is managed by administrator, you can just configure the 10.100.100.8 on some device of external network	07:42
yuli_s	I have it is place	07:42
yuli_s	br-ex has addr:10.100.100.8	07:43
openstackgerrit	Merged openstack/dragonflow: OVSDB monitor to filter port update events https://review.openstack.org/297188	07:43
yuli_s	raofei, what you advise me to do ?	07:44
yuli_s	i do not see any icmp packets on br-ex	07:45
raofei	you need to tcpdump whether br-ex send arp to br-int	07:45
raofei	you just ping fip -I 10.100.100.8	07:45
raofei	to trigger the arp	07:46
raofei	or you can do as below. tcpdump -i br-ex -n arp	07:47
raofei	and then restart df-controller	07:47
raofei	we need to capture the arp request from controller on br-ex	07:47

raofei	it's because df controller CANNOT learn the gateway arp, so there is a rule missing.	08:17
raofei	That's why I ask you to capture the arp request from controller on br-ex!!!	08:18
raofei	@Yuli, please configure the gateway ip into an external network device. and add a physical nic into br-ex, and this physical nic connect the external network.	08:27

yuli_s	i can ping 10.100.100.8 from other host	10:01
yuli_s	ping to 10.100.201.200 from other server is not working	10:01
yuli_s	gal we have a problem running ping from VM to outer world	10:03
yuli_s	only ping to local gw works	10:03
yuli_s	on public network subnet	10:08
yuli_s	1. i tried to use Ip assigned on br-ex	10:08
yuli_s	1. i tried to use Ip oh physical gw	10:08
yuli_s	2. i tried to use Ip of physical gw	10:09
yuli_s	in openflow rules we have table 30 missing (EGRESS_NAT_TABLE = 30)	10:09
yuli_s	<raofei> it's because df controller CANNOT learn the gateway arp, so there is a rule missing.\	10:10
yuli_s	so, as raofei suggested there is a problem with ARP packets	10:11
yuli_s	somewhere in my lab	10:11
yuli_s	so, we are trying to debug this	10:12
raofei	if your setup is built on vm(with nested vm), then it's vey easy to set the external gateway.	10:13
yuli_s	btw, what should I use as a gateway_ip in pub-subnet ?	10:14
yuli_s	btw, what IP should I use as a gateway_ip in pub-subnet ?	10:14
raofei	gateway_ip \| 10.100.100.1	10:14
raofei	this is the external gateway ip	10:15
yuli_s	ok great,	10:15
raofei	btw, you need disable the q-l3	10:15
yuli_s	this IP I used for the last few hours	10:15
yuli_s	it is disabled and not running	10:16
gsagie	raofei: the controller learn the physical gateway using learn flows?	10:17
gsagie	i guess you mean the physical gateway MAC	10:17
gsagie	is there anyway that yuli_s can first hard code the MAC and try it out	10:18
yuli_s	raofei, can you point me to Openflow rule where the df controller receives the gateway arp ?	10:24

oanson	Hi. It looks like the gw ip is defined badly. It should be 10.100.100.1. It looks like its configured to be 10.100.0.1. yuli_s will look into it in his env.	12:04
yuli_s	ok	12:11
yuli_s	in df db	12:11
yuli_s	Key = cb3f53f3-2694-4924-8b31-a7735906610c , Value = {"topic": "85104976665e47cfaefe8ad50e7de019", "subnets": [{"dhcp_ip": "10.100.0.2", "enable_dhcp": true, "lswitch": "cb3f53f3-2694-4924-8b31-a7735906610c", "dns_nameservers": [], "gateway_ip": "10.100.100.1", "cidr": "10.100.0.0/16", "id": "17c869eb-909c-464b-9572-e555cb044230"}], "external_ids": {"neutron:network_name": "pub-external"}, "name": "cb3f53f3-2694-4924-8b31	12:12
yuli_s	-a7735906610c"}	12:12
yuli_s	so, in df db we have a correct gateway ip - "gateway_ip": "10.100.100.1"	12:12
yuli_s	in openflow rules we have:	12:14
yuli_s	cookie=0x0, duration=6411.445s, table=15, n_packets=0, n_bytes=0, priority=100,arp,arp_spa=10.100.0.1,arp_tpa=10.100.201.200,arp_op=2 actions=CONTROLLER:65535	12:14
yuli_s	cookie=0x0, duration=6411.445s, table=15, n_packets=0, n_bytes=0, priority=100,arp,arp_spa=10.100.0.1,arp_tpa=10.100.0.1,arp_op=1 actions=CONTROLLER:65535	12:14
yuli_s	so, you need to alter these rules on gateway_ip change event	12:14
yuli_s	here is a command I used to change gateway_ip:	12:16
yuli_s	neutron subnet-update 17c869eb-909c-464b-9572-e555cb044230 --gateway_ip 10.100.100.8	12:16

raofei	Hi yuli, current dnat doesn't process the subnet update event and router update event. it will be supported later.	12:28
raofei	so please test dnat without change external subnet gateway.	12:29
yuli_s	ok, great !	12:30
yuli_s	it is very strange	12:30
raofei	dnat APP doesn't process these two updation event.	12:30
yuli_s	my recommendations might not be fully correct.	12:30
yuli_s	this is is taken from floatingip table : "external_gateway_ip": "10.100.0.1"	12:31
yuli_s	this IP is taken from floatingip table : "external_gateway_ip": "10.100.0.1"	12:31
yuli_s	i have restarted DF controller,	12:31
yuli_s	the old value is still in use ("10.100.0.1") and not ("10.100.100.1"	12:32
raofei	I think when you create external subnet first time, the gateway ip is 10.100.0.1	12:32
yuli_s	yes !	12:32
yuli_s	this where from this IP is originating	12:33
*** openstackgerrit has quit IRC		12:33
