#openstack-nova - 2019-08-29
19:21:07 sean-k-mooney is ther more then one node
19:21:34 sean-k-mooney if so it should work. you can always try booting a vm with that flavor too
19:21:41 sean-k-mooney if it works then its all good
19:23:02 sean-k-mooney on a numa host it will look like this
19:23:04 sean-k-mooney stack@cloud-3:~/devstack$ ls /sys/bus/node/devices/
19:23:06 sean-k-mooney node0 node1
19:23:21 sean-k-mooney or in your case you should have node 0-3
19:31:18 openstackgerrit Merged openstack/nova master: rt: soften warning case in _remove_deleted_instances_allocations https://review.opendev.org/673873
19:33:11 donnyd sean-k-mooney: I will check it out and report back
19:35:22 donnyd node0 node1 node2 node3
19:35:22 donnyd ubuntu@compute-1:~$ sudo ls /sys/bus/node/devices/
19:37:39 donnyd woot woot
19:38:05 sean-k-mooney yep that all looks fine
19:39:08 donnyd another plus is that flavor also already has a bit more for memory, so that may be helpful on the nested virt side
19:39:32 sean-k-mooney it will be helpful for hugepage testing in the vm
19:40:05 sean-k-mooney because it means its less of a blancing act between the memroy needed for openstack vs the nested vms
19:40:25 donnyd i don't have hugepages enabled
19:40:33 sean-k-mooney you dont need them on the host
19:40:41 sean-k-mooney if you look at https://review.opendev.org/#/c/652197/20/playbooks/nfv/nfv.yaml
19:41:00 sean-k-mooney you see in my curent nfv job i ame allocating only a limited amount
19:41:01 donnyd do i look for the same parameters inside the vm?
19:41:24 sean-k-mooney how do you mean
19:41:39 sean-k-mooney do you mean the cpu flags
19:41:52 donnyd looking for numa nodes inside the instance launched with that flavor
19:42:00 donnyd the instance created fine
19:42:09 donnyd but how do i tell if its right
19:42:15 sean-k-mooney oh ya if you run the sam command in the vm you shoudl see 2
19:42:24 prometheanfire how's the lxml issue coming?
19:42:41 sean-k-mooney i need to rework it to use the helper function
19:42:44 donnyd there is no /sys/bus/node dir
19:42:45 sean-k-mooney but its fixed
19:43:05 sean-k-mooney really?
19:43:09 donnyd no
19:43:24 sean-k-mooney what kernel/os is the vm using
19:43:31 donnyd i am going to try again with a different image and maybe not use one i am developing on
19:43:45 sean-k-mooney prometheanfire: https://review.opendev.org/#/c/678964/
19:44:14 sean-k-mooney ill respin it sortly to use self.assertXmlEqual
19:44:25 sean-k-mooney but once thats done it should be good to go.
19:44:33 sean-k-mooney prometheanfire: can you unabandon your change by the ay
19:44:39 sean-k-mooney *way
19:44:49 sean-k-mooney prometheanfire: https://review.opendev.org/#/c/673848/
19:45:42 openstackgerrit Matt Riedemann proposed openstack/nova master: Test heal port allocations in nova-next https://review.opendev.org/669879
19:45:55 prometheanfire the lxml change?
19:45:58 donnyd yea, i tried with a different image and its good to go
19:46:10 prometheanfire done
19:46:21 sean-k-mooney donnyd: cool can you provide the output of lcpu from the guest too
19:46:25 prometheanfire should I update it to 4.4.1?
19:46:35 sean-k-mooney i just want to check the flags
19:46:50 sean-k-mooney prometheanfire: i used the latest version on pypi for my testing
19:46:59 sean-k-mooney so you can updated it to whatever that is
19:47:11 donnyd u mean lscpu
19:47:11 prometheanfire wfm
19:47:19 sean-k-mooney yes
19:47:33 donnyd https://www.irccloud.com/pastebin/dvV8SBKk/
19:48:30 sean-k-mooney yep so that supports hugepages and vmx is there so nested virt will work in the vm
19:48:46 sean-k-mooney and it have avx/sse4 so dpdk would work too
19:49:13 sean-k-mooney donnyd: also you can see it has 2 numa nodes
19:49:26 donnyd pretty slick
19:49:29 donnyd that was easy
19:49:45 sean-k-mooney donnyd: this is totally optionaly but can i ask you to tweek somthing else that annoys me
19:49:47 donnyd anything else you need to see
19:49:50 donnyd sure
19:50:26 sean-k-mooney can you add hw:cpu_sockets=2 hw:cpu_cores=2 hw:cpu_threads=2
19:50:47 donnyd sure thing
19:50:57 sean-k-mooney that will emulatate a 2 socekt system with 2 core cpus with hyperthreading
19:51:12 sean-k-mooney currently the vm thing it has 8 sockets
19:52:08 donnyd more sockets are more better
19:52:31 sean-k-mooney not when windows and vmware licening used to be per socket
19:52:39 sean-k-mooney although now its per core
19:53:24 donnyd sean-k-mooney: more sockets is web scale
19:53:34 openstackgerrit Matt Riedemann proposed openstack/nova master: Add FUP unit test for port heal allocations https://review.opendev.org/672142
19:54:47 sean-k-mooney the e7 line goes up to 8 i belive an then you get int the craze hyper scaleble skus
19:54:49 donnyd https://www.irccloud.com/pastebin/QLruofuP/
19:55:12 sean-k-mooney thanks
19:55:15 sean-k-mooney much sainer
19:55:23 donnyd NP
19:55:51 donnyd at some point we probably want to update the labels to reflect what they actually do - but its fine for now
19:55:52 sean-k-mooney ok ill try this configurtion and see if i hit any road blocks. proably next week however.
19:56:01 donnyd yea that is cool
19:56:20 sean-k-mooney well it still has 8 cpus and 16 GB of ram adn 80G of disk
19:56:31 sean-k-mooney they are now jsut arranged a little differently
19:56:32 donnyd yes
19:56:44 donnyd that is a true story
19:56:58 donnyd hope nova can make use of it
19:57:11 donnyd lmk if there is anything else i can do in FN to make lives easier
19:57:59 sean-k-mooney i think you have done more then enough for now. the next step is on us/me to get an experimtal job using it
20:01:00 donnyd btw for those who won on the bet, I am going to need a piece of that
20:01:14 donnyd :) :) :)
