| 12:44:11 | sean-k-mooney | which can degreed performance so if you have not already tried expliclty having only 1 numa node in the guest that is wroth testing | |
| 12:44:33 | grami[m] | Ah yeah right now I'm going to see if I can get the instance to work by editing the xml then will look to see what needs to change. | |
| 12:45:10 | grami[m] | Yeah made sure it's only one numa zone for testing and will go from that. | |
| 12:46:53 | sean-k-mooney | right now i dont know of a way to change the bar space allocated to the viruatlised device. i assuem that need qemu supprot and im not sure if livbirt and qemu are hooked up such that it can be adjusted | |
| 12:47:48 | sean-k-mooney | there is memReserve | |
| 12:47:56 | sean-k-mooney | ```memReserve | |
| 12:47:58 | sean-k-mooney | Some PCI devices have non-prefetchable memory bar larger than 2MiB. Use this attribute to override value computed by firmware and thus make controller reserve more memory (in KiB) so that such PCI device can be hot plugged. For cold plugged PCI devices, the firmware will automatically reserve the correct amount of memory``` | |
| 12:48:25 | sean-k-mooney | but i dont think that is correect | |
| 12:59:59 | sean-k-mooney | grami[m]: you not trying to use resizable bar ar you? | |
| 13:04:16 | sean-k-mooney | just doing a little quick resarch qemu/libvirt wont do the resize for you you have to do that manually today before bindign the device to vfio-pci. second there is a limisation in ovmf by default where the adress apce resverd sames to default to 32GB for mmio mappings https://edk2.groups.io/g/discuss/topic/59340711 | |
| 13:05:37 | sean-k-mooney | we do not allow any use of <qemu:commandline> in nova so you woudl need that to be supproted in libvirt nativly before turnign the mmio apature via "fw_cfg name=opt/ovmf/X-PciMmio64Mb,string=65536" coudl be supproted | |
| 13:05:56 | gibi | sean-k-mooney: | |
| 13:06:07 | gibi | thanks for the review in https://review.opendev.org/c/openstack/nova/+/954149 | |
| 13:06:42 | gibi | I responded inline. bottom line your reserved idea is probably correct, but I'm afraid of the complexity of the patch already | |
| 13:07:08 | sean-k-mooney | gibi: that not a blocker | |
| 13:07:16 | sean-k-mooney | we can consider it in a followup | |
| 13:07:24 | sean-k-mooney | i was jsut trying to think is there a way to close that gap | |
| 13:09:21 | grami[m] | sean-k-mooney: Yeah had to add that Nvidia says it's a requirement for the larger gpus | |
| 13:09:50 | sean-k-mooney | grami[m]: based on https://bugzilla.redhat.com/show_bug.cgi?id=1578278 it looks lime https://specs.openstack.org/openstack/nova-specs/specs/2023.1/approved/libvirt-maxphysaddr-support.html may also impact that | |
| 13:09:57 | sean-k-mooney | but i dont think the two ar the same | |
| 13:10:12 | grami[m] | Already have a patch for this but it's medieval in its method but works for now. | |
| 13:10:16 | sean-k-mooney | we cant accapt any change that uses raw <qemu:commandline> elements in nova | |
| 13:10:52 | sean-k-mooney | so if we need to tweak the ovmf parmater seperatly form teh cpu adress space | |
| 13:10:58 | sean-k-mooney | we will need to modify libvirt first | |
| 13:11:52 | grami[m] | Ah thanks for that | |
| 13:37:43 | opendevreview | ribaudr proposed openstack/nova master: doc: mark the maximum microversion for 2025.2 Flamingo https://review.opendev.org/c/openstack/nova/+/959180 | |
| 13:40:42 | opendevreview | ribaudr proposed openstack/nova master: Update compute rpc alias for epoxy https://review.opendev.org/c/openstack/nova/+/959181 | |
| 13:41:01 | gibi | sean-k-mooney: it is the freqency and the impact of the gap vs. my fears of the complexity to close and test that gap is what makes me reluctant | |
| 13:45:44 | gibi | bauzas: re | |
| 13:45:45 | gibi | 10:32 < bauzas> honestly, I don't have any number, if the job works up to tomorrow, then if so, let's leave it to be voting :) | |

| 16:04:25 | Uggla | Anythink special with the gates ? | |
| 16:04:33 | Uggla | Anything special with the gates ? | |
| 16:04:34 | gibi | just a heads up | |
| 16:05:15 | gibi | that I see multiple cases when the ceph multistore job failed due to volume build issues and mostly in the encrypted volume tempest tests | |
| 16:05:41 | gibi | I did not dig deeper but I feel it is a pattern | |
| 16:07:06 | Uggla | an idea of the success/failure rate ? | |
| 16:07:30 | gibi | https://zuul.opendev.org/t/openstack/builds?job_name=nova-ceph-multistore&project=openstack/nova | |
| 16:07:33 | gibi | not terrible | |
| 16:08:49 | gibi | I will try to dig into the failure tomorrow | |
| 16:08:59 | Uggla | ok thanks gibi | |
| 16:09:16 | Uggla | although that looks not easy. | |
