| 12:36:31 | mriosfer | Hi, We got Openstack Queens RDO. Some customers are telling us that their Windows VM CPU performs bad as a hell. We deployed the lasted virtio already to check improvements. I got a video an its true work its frustating, I/O is less than <1ms | |
| 12:40:34 | sean-k-mooney | what are you deploying on libvirt/kvm | |
| 12:41:42 | sean-k-mooney | the first thing i woudl do is alter the cpu topology to be sane for windows | |
| 12:41:56 | sean-k-mooney | by defualt we allcoate 1 cpu socket per favor.vcpu | |
| 12:42:34 | mriosfer | we're ussing quemu-kvm for instances . | |
| 12:42:41 | sean-k-mooney | if the guest dont have a numa toplogy set hw:cpu_sockets=1 and hw:cpu:threads=2 | |
| 12:42:43 | mriosfer | How do you do that? | |
| 12:42:59 | sean-k-mooney | assuming the host has Hyper thread enabled. | |
| 12:43:04 | mriosfer | yes of course | |
| 12:43:19 | mriosfer | do you setup that extra features in the flavors? | |
| 12:43:35 | sean-k-mooney | yes you can do it in the flavor or image | |
| 12:43:50 | sean-k-mooney | in the image its hw_ instead of hw: | |
| 12:44:00 | mriosfer | i prefer image | |
| 12:44:31 | sean-k-mooney | that should help the windows shcduler if you have more then 4 vcpu in the vm | |
| 12:44:45 | mriosfer | yes.. some cpu got 8cpu or 12vcpu | |
| 12:44:57 | mriosfer | and with terminal server the performance its terrible | |
| 12:45:07 | sean-k-mooney | ya so windows will see that as 8 to 12 cpu sockets with out default setting | |
| 12:45:30 | sean-k-mooney | the next thing to look at would be the graphics device model | |
| 12:45:38 | sean-k-mooney | you said you were on queens | |
| 12:45:41 | mriosfer | yes | |
| 12:45:59 | mriosfer | our nodes dont have pcie addtional graphic card just the integrated one by Dell | |
| 12:46:09 | sean-k-mooney | ya that is ok | |
| 12:46:44 | sean-k-mooney | on train+ would suggest using the virtio gpu but on queens you should set hw_video_model=qxl | |
| 12:47:18 | sean-k-mooney | i belive qxl is the best performing graphic device that qemu can emulate prior to support for virtio | |
| 12:47:28 | sean-k-mooney | https://github.com/openstack/glance/blob/master/etc/metadefs/compute-libvirt-image.json#L71-L84 | |
| 12:47:47 | sean-k-mooney | you could also use the hw_video_ram element to increase that | |
| 12:47:57 | sean-k-mooney | i belive it default to 64mb | |
| 12:48:07 | mriosfer | thath ram uses the instance ram no? | |
| 12:48:13 | sean-k-mooney | no | |
| 12:48:16 | sean-k-mooney | its addtional host ram | |
| 12:48:24 | mriosfer | oh , ok | |
| 12:48:41 | sean-k-mooney | it can only be set on the image if the flavor allows it by setting hw_video:ram_max_mb | |
| 12:49:25 | sean-k-mooney | i would start with the qxl video model and then if that is not enough after the cpu changes then increae the ram to say 128 or 256 | |
| 12:49:46 | mriosfer | sean do you know why error? https://gyazo.com/10156259f833a20decbdce821ef8e31b | |
| 12:50:06 | sean-k-mooney | yes | |
| 12:50:18 | sean-k-mooney | this is one of the model that is in the metadefs | |
| 12:50:24 | sean-k-mooney | so there is a drop down for it | |
| 12:50:32 | sean-k-mooney | use the filter box above | |
| 12:50:37 | sean-k-mooney | instead of a custom filed | |
| 12:51:21 | sean-k-mooney | our you can scoll down there should be a libvirt dropdown in the availabel metadata | |
| 12:51:47 | mriosfer | oh | |
| 12:51:56 | mriosfer | im fuck*** noob | |
| 12:52:09 | sean-k-mooney | the gui is "trying" to be help full | |
| 12:52:26 | sean-k-mooney | it actully really annoyed me when they added that "feature"] | |
| 12:52:46 | mriosfer | rebooting instance will apply the new changes? | |
| 12:52:52 | sean-k-mooney | no | |
| 12:52:55 | sean-k-mooney | unfortunetly not | |
| 12:53:05 | sean-k-mooney | you can only update the instnace with a rebuild | |
| 12:53:13 | sean-k-mooney | which would loose data on the root disk | |
| 12:53:18 | mriosfer | oh fuck | |
| 12:54:03 | sean-k-mooney | we make a copy of the data in the vm when we boot it so that it intentionall will not be affected by change in glance | |
| 12:54:19 | sean-k-mooney | if we did not you could break all your deployed vms with a typo | |
| 12:54:24 | sean-k-mooney | which would be bad | |
| 12:54:49 | sean-k-mooney | in your case once you are happy with the final image and its performace | |
| 12:55:02 | mriosfer | mmm maybe i can do a workarround at ceph level :) | |
| 12:55:04 | sean-k-mooney | you could do a db update to add the missing keys to the copy | |
| 12:55:42 | sean-k-mooney | then a hard reboot of the vm would fix it | |
| 12:56:20 | sean-k-mooney | i belive we store the instance image keys in the system_metadata table prefixed with img_ | |
| 12:56:28 | mriosfer | now looks much better the image : https://gyazo.com/cacf129fc79e2f1b23b607704b645d71 | |
| 12:56:59 | sean-k-mooney | yes but you will need to update the flaovr to have the hw_video_ram work | |
| 12:58:20 | sean-k-mooney | the reason being we did not want tenant to be abel to upload there own image and request 256GB of video ram | |
| 12:59:08 | mriosfer | do you also setup the Max vCPU threats and vCpu Cores at flavor level? | |
| 12:59:39 | sean-k-mooney | you dont need too but can | |
| 12:59:49 | sean-k-mooney | for the video ram it will hit this code https://github.com/openstack/nova/blob/a948a803b561606a892133940915caae610c080b/nova/virt/vmwareapi/vmops.py#L334-L338 | |
| 13:00:16 | mriosfer | that just for vmware no? | |
| 13:00:32 | sean-k-mooney | oh wrong file let me check the libvirt driver | |
| 13:00:43 | sean-k-mooney | vmware would reject it if the flavor is not set | |
| 13:01:44 | sean-k-mooney | ya its the same https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L5057-L5063 | |
| 13:01:57 | sean-k-mooney | i would just lave that out for now | |
| 13:02:21 | sean-k-mooney | as you would also have to update the embeded copy of the flavor or do a resize to pick up the change | |
| 13:02:56 | mriosfer | yes i will do for sure | |
| 13:02:58 | sean-k-mooney | if you find qxl and the toplogy chagne are not enough the try the ram change | |
| 13:03:14 | mriosfer | if it works i will send you a pack a beers! | |
| 13:03:59 | sean-k-mooney | ha :) well on other question is the slowness you are finding with the horizon console or do you still see that with rdp in the guest | |
| 13:04:13 | mriosfer | i see in the rdp guest | |
| 13:04:25 | stephenfin | bauzas: Assuming efried and dansmith aren't online yet, I think you ought to look at this and send it through so we can unblock neutron | |
| 13:04:26 | mriosfer | i dont recomend users work through horizon | |
| 13:04:29 | sean-k-mooney | right ok then ya this shoudl help | |
| 13:04:42 | stephenfin | We can use a follow-up if dansmith isn't happy with any of my answers | |
| 13:05:03 | sean-k-mooney | i have seen issue with novnc adding lag in the past | |
| 13:05:05 | bauzas | stephenfin: which change do you want me ? | |
| 13:05:12 | stephenfin | bauzas: oh, whoops https://review.opendev.org/#/c/705760 | |
