| ralonsoh | I think we have, again, a problem with the DHCP agent | 11:36 |
| ralonsoh | the port to be added to the router is never provisioned by any DHCP agent | 11:36 |
| slaweq | ralonsoh: so the issue which obondarev was trying to solve some time ago, right? | 11:38 |

| obondarev | ralonsoh: looks like in last case 1 of 2 dhcp agents hanged and the second one does not host the net. So port was not handled | 11:49 |
| ralonsoh | obondarev, exactly | 11:50 |
| obondarev | wondering if updating config for number of agents hosting net could help | 11:50 |
| obondarev | but again only a workaround | 11:50 |
| ralonsoh | yes, this is a workaround until we can fix the privsep problems | 11:52 |
| obondarev | lajoskatona: the patch dealing with privsep was not landed, right lajoskatona? | 11:52 |
| ralonsoh | nope | 11:52 |
| lajoskatona | no | 11:52 |

| spatel | ralonsoh is it possible my floating use SRIOV? | 16:46 |
| spatel | also VxLAN tunnel traffic run on SRIOV also? | 16:47 |
| ralonsoh | spatel, sorry what? | 16:47 |
| spatel | I want high performance networking throughput in my openstack network layer | 16:47 |
| spatel | Example tenant traffic run on SRIOV or DPDK using vxlan or genev tunnel. (something like that) | 16:48 |
| spatel | is it possible ? i am new in that design so asking question myself | 16:48 |
| ralonsoh | SRIOV only supports flat and VLAN | 16:49 |
| ralonsoh | https://github.com/openstack/neutron/blob/master/neutron/plugins/ml2/drivers/mech_sriov/mech_driver/mech_driver.py#L89 | 16:49 |
| ralonsoh | not tunneled networks | 16:49 |
| spatel | ah! make sense | 16:50 |
| ralonsoh | and about having a FIP with a SRIOV port, doesn't make sense | 16:50 |
| spatel | what about DPDK ? | 16:50 |
| ralonsoh | why would you do DNAT on a port that should be connected directly to a external switch? | 16:50 |
| spatel | does that support tunnel and FIP? | 16:50 |
| ralonsoh | OVS+DPDK? | 16:51 |
| ralonsoh | OVN+DPDK? | 16:51 |
| spatel | Yes OVS+OVN + DPDK | 16:51 |
| ralonsoh | with OVN, if you use DVR (this is the default config), I makes sense to have FIP if you need | 16:52 |
| ralonsoh | that will be DNATed inside the same OVS | 16:52 |
| spatel | i am just exploring all option for my nest new cloud, requirement is to have high network throughput and low latency | 16:52 |
| ralonsoh | with OVS you'll need to send it to iptables | 16:52 |
| ralonsoh | you loose the advantage | 16:53 |
| spatel | >> with OVS you'll need to send it to iptables ?? | 16:53 |
| ralonsoh | this is how fixed IP is DNATed to FIP | 16:54 |
| spatel | not for OVN right? | 16:59 |
| ralonsoh | OVN implements everything with OpenFlow rules. With DVR, this DNAT will be done inside the same OVS instance, in the same datapath | 17:00 |
| spatel | In short SRIOV not supported for tunnel but DPDK does support right? | 17:00 |
| ralonsoh | not DPDK, but OVS or OVN | 17:01 |
| ralonsoh | DPDK is just a particular implementation of OVS | 17:01 |
| spatel | hmm! then how does people run high performance networking for inter VM communication? | 17:01 |
| ralonsoh | ? | 17:02 |
| ralonsoh | what does it means? | 17:02 |
| spatel | If i create VPC and spin up two vm1 and vm2 on two different compute node then they will use VxLAN tunnel to communicate with each other right? | 17:03 |
| spatel | if vm1 sending lots of traffic to vm2 then there will be poor performance if they use tap interface because all packet processing happened in Linux kernel.. | 17:03 |
| spatel | am i wrong here? | 17:03 |
| ralonsoh | depending on how you want to send the traffic | 17:04 |
| ralonsoh | if you are using tenant networks | 17:04 |
| ralonsoh | and those networks use VLAN | 17:04 |
| spatel | I am talking about tenant traffic | 17:04 |
| ralonsoh | you can use (1) SRIOV, the traffic will go from a SRIOV port to another SRIOV port | 17:05 |
| ralonsoh | (2) OVN+DPDK or OVS+DPDK if you don't have SRIOV | 17:05 |
| spatel | But again question is does DPDK solution work with tenant traffic? | 17:05 |
| ralonsoh | this is not a yes or not answer | 17:06 |
| ralonsoh | for OVS with VLAN traffic, the physical bridges will be connected to NICs | 17:07 |
| ralonsoh | those NICs will be in the same L2 domain | 17:07 |
| ralonsoh | those NICs will use DPDK ports --> that will be valid for high speed | 17:08 |
| ralonsoh | with OVS and tunneled traffic, there is a method to drive the tunneled traffic trhough the physical bridges | 17:08 |
| spatel | That is what i have in my current datacenter, all my VM directly connected to L2 domain of my physical switch fabric and i don't have any tenant traffic and life is good | 17:08 |
| ralonsoh | that provides the same high speed | 17:08 |
| spatel | >> with OVS and tunneled traffic, there is a method to drive the tunneled traffic trhough the physical bridges - This is i want to know and deploy in new datacenter | 17:09 |
| ralonsoh | I don't know if this is officially supported, but there is a project that provides this | 17:09 |
| ralonsoh | https://opendev.org/x/networking-ovs-dpdk | 17:10 |
| spatel | hmm if i attach my vxlan nic directly to sriov or dpdk then it should work right? | 17:10 |
| spatel | (vxlan bridge i meant) | 17:10 |
| ralonsoh | not at all | 17:10 |
| ralonsoh | again, with SRIOV you don't have tunneled traffic | 17:11 |
| ralonsoh | and with dpdk you need to redirect the tunneled traffic trough a physical bridge | 17:11 |
| spatel | I got your point SRIOV is like physical interface | 17:11 |
| spatel | Let me play with DPDK to see if i can utilize it with tenant traffic. (may need to run some experiment) | 17:12 |
| spatel | I have build 5 node OVN lab, and noticed lots of flows got installed by default on each compute nodes, I am having hard time to understand some of them. | 17:14 |
| spatel | Is there any doc about what are these flows and what is the use of them.. ? | 17:14 |
| spatel | does more flows create any performance issue with OVS? because packet need to travel each flow table | 17:15 |
