| 21:29:55 | sean-k-mooney | its just slower, more work and not supported by openstack by defualt | |
| 21:30:17 | spatel | Got it.. so hugepage has big role here | |
| 21:30:34 | sean-k-mooney | if you are using a new enought ovs-dpdk you can actully get 0 copy packet transmistion betwwen the guest and the nic | |
| 21:31:17 | openstackgerrit | Merged openstack/nova master: update constraints url https://review.opendev.org/664771 | |
| 21:31:19 | sean-k-mooney | e.g. when the guest kernel rights the packet to the tx queue it is nver copyied and is drieectly trasmited by the nic similar to sriov | |
| 21:31:34 | sean-k-mooney | 0 copy recive i think is also posibel but experimental | |
| 21:32:12 | sean-k-mooney | that obviorsly depend on if you are using vxlan or vlans feature that may or may not be supported in your nic hardware | |
| 21:32:20 | spatel | ah! ok.. in short it bypass the kernel | |
| 21:32:47 | sean-k-mooney | yep and does everything in userspacce or in hardaware | |
| 21:33:07 | spatel | Do you guys running dpdk in production? | |
| 21:33:31 | spatel | very few people i found using dpdk in prod cloud | |
| 21:33:36 | sean-k-mooney | well i dont run a production cloud. i just work on upstream stuff | |
| 21:33:56 | sean-k-mooney | spatel: but redhat has customer using it in production yest | |
| 21:34:01 | sean-k-mooney | *yes | |
| 21:34:19 | sean-k-mooney | it is much less common then kernel ovs or sriov | |
| 21:34:28 | spatel | Let see how successful i can run in my production. | |
| 21:35:05 | sean-k-mooney | if you want the full intel pitch then https://software.intel.com/en-us/articles/yahoo-japan-accelerates-l7-performance-using-open-vswitch-with-dpdk | |
| 21:35:52 | spatel | Thanks for that link.. | |
| 21:36:53 | sean-k-mooney | hehe when i was working at intel i help some of the yahoo folk tuen there deployment alittle but after it was working i never heard form them how it worked out long term | |
| 21:37:55 | spatel | sean-k-mooney: you are smarty pants :) | |
| 21:39:04 | spatel | sean-k-mooney: hope dpdk support bonding too | |
| 21:39:40 | sean-k-mooney | it does | |
| 21:39:58 | sean-k-mooney | you can have dpdk do it(not recommended) or use ovs bonding of dpdk ports | |
| 21:40:22 | sean-k-mooney | ovs bonding give you more contol and can be modifed while the switch is running | |
| 21:40:57 | sean-k-mooney | dpdk bonding required the switch to be restareted, is less configurable but used to be slight faster at failover and throuput | |
| 21:41:20 | sean-k-mooney | honestly however dpdk bonding not via ovs is an operations pain that is best avoid | |
| 21:41:32 | sean-k-mooney | you should just use ovs bonding | |
| 21:41:42 | sean-k-mooney | anyway im gong to call it a night o/ | |
| 21:43:52 | spatel | sean-k-mooney: Thank you for wonderful tips | |
| 21:43:54 | spatel | Good night | |

| 00:21:01 | izza_ | Hi,can anybody here help me pls...i'm testing rally heat(scenario: create_stack_scale) and i'm encountering below error: ***heat-engine***** 2019-06-13 18:27:19,809.809 1 ERROR heat.engine.service ResourceFailure: resources.asg: HEAT-E99001 Service nova is not available for resource type OS::Nova::Server, reason: Authentication cannot be scoped to multiple targets.

| 00:23:34 | izza_ | i badly needed ur help guys...i have deadline Today | |
| 00:45:05 | sean-k-mooney | izza_: i think you need to try the heat or rally channel. this looks liek an issue with the heat templat that rally is using | |
| 00:45:20 | sean-k-mooney | izza_: i dont think this is related to nova from that error | |
| 00:50:41 | igordc | hello sean-k-mooney | |
| 00:51:02 | sean-k-mooney | igordc: o/ | |
| 00:51:04 | igordc | sean-k-mooney, since you're here, can I ask if you had a look at https://review.opendev.org/#/c/576607/ after Stamatis last comment? | |
| 00:51:18 | igordc | cc stephenfin | |
| 00:51:31 | sean-k-mooney | i have not | |
| 00:51:42 | izza_ | ok noted..i already sent message to rally channel...yet no answer..just looking for a chance..if anyone knows how to resolv that issue..but thanks:) | |

| 13:48:35 | dansmith | lyarwood: did you see mriedem's query about "q35" on the master patch for the sata bus thing? | |
| 14:11:58 | artom | dansmith, lyarwood at a medial appointment, but we've volunteered kashyap to follow up on that just now during our internal bug call :) | |
| 14:13:06 | artom | dansmith, while I have you, is looking at https://review.opendev.org/#/c/644881/ again anywhere near the top of your review list? | |
| 14:14:17 | dansmith | artom: mriedem has been shitting on my reviews all week, so I'm going to wait for him to +2 that | |
| 14:14:21 | kashyap | artom: Got a link to the backport patch? | |
| 14:14:33 | dansmith | kashyap: the backport isn't in question, it's the merged master one | |
| 14:14:52 | dansmith | kashyap: https://review.opendev.org/#/c/663011/ | |
| 14:15:06 | artom | Jinx! | |
| 14:15:28 | artom | dansmith, :( for mriedem. I may have been too pestery with him yesterday | |
| 14:17:27 | kashyap | dansmith: Matt answered the casing question, just saw that :) | |
| 14:18:13 | dansmith | kashyap: oh sorry, hadn't refreshed my tab | |
| 14:18:40 | kashyap | dansmith: No-no, but still it's a good question, the answer is not "complete" | |

| 14:18:56 | dansmith | I'm guessing that if someone puts Q35 we'll just break, but earlier because we pass that to qemu? | |
| 14:19:35 | kashyap | dansmith: Yes, that's what I'd expect; I wonder if there's equivalent of 'ignore_case' for image properties | |
| 14:20:03 | dansmith | kashyap: well, it's all in the handling of it really | |
| 14:20:13 | kashyap | For now, we're not in the ditch: as Matt noted, libvirt itself reports (in its capabilities) it in lower case | |
| 14:20:48 | dansmith | yeah, the patch doesn't make it worse, which is all that matters for the backport, that's fine | |
| 14:23:55 | kashyap | And we can rely on "instinctive laziness" of most folks, in terms of casing: people tend to "default" to lower case, as it comes "naturally" :D | |
