| 12:42:47 | sean-k-mooney | well there too but i was not reading the comit message | |
| 12:43:13 | sean-k-mooney | i rember this form when the rng supprot was first beign added | |
| 12:43:15 | kashyap | Righ; I wrote the code comment in image_meta.py | |

| 13:14:05 | dansmith | gibi: ah, based on the time, it must have been the last one before I went to bed, cool | |
| 13:19:27 | gibi | dansmith: yepp you almost saw the patch landing | |
| 13:19:30 | gibi | :) | |
| 13:21:36 | dansmith | well, sorry | |
| 13:22:54 | gibi | no worries. I'm glad you pushed the patch forwatrd | |

| 14:34:04 | sean-k-mooney | gibi: ill take a look now | |
| 14:34:26 | sean-k-mooney | gibi: a gmann has don it alredy | |
| 14:34:28 | gibi | sean-k-mooney: thanks | |
| 14:34:51 | gibi | ohh | |
| 14:35:03 | sean-k-mooney | gmann++ | |
| 14:35:15 | gibi | thanks then | |
| 15:08:12 | artom | sean-k-mooney, hey, in https://review.opendev.org/c/openstack/nova/+/783084/1/nova/tests/functional/libvirt/test_pci_sriov_servers.py#382 when you say it's a side effect of our Neutron fixture, what did you mean? | |
| 15:08:36 | artom | Btw, that should have been WIP :P | |
| 15:08:48 | artom | I'm just starting to explore wth's going on | |
| 15:08:52 | sean-k-mooney | i mean that in reality you will not get that key error | |
| 15:09:06 | sean-k-mooney | the pci_slot key will be set in the profile | |
| 15:09:12 | sean-k-mooney | it just will have the wrong value | |
| 15:09:22 | sean-k-mooney | so your test is failing but not for the correct reason | |
| 15:09:49 | sean-k-mooney | did you see my top level comment | |
| 15:09:57 | artom | sean-k-mooney, right, so... 1. what bit in the fixture isn't like reality? and 2. dvd seems to have gotten the same keyerror here: https://bugzilla.redhat.com/show_bug.cgi?id=1767797#c17 | |
| 15:09:59 | sean-k-mooney | i suggested how to write the test diffeerntly | |
| 15:09:59 | openstack | bugzilla.redhat.com bug 1767797 in openstack-nova "When unshelving an SR-IOV instance, the binding profile isn't reclaimed or rescheduled, and this might cause PCI-PT conflicts" [High,Assigned] - Assigned to alifshit | |
| 15:10:49 | artom | sean-k-mooney, yeah, I actually started like that, and then went back because... well, I wasn't thinking straight. Lemme do it "properly", and upload that I find | |
| 15:11:12 | sean-k-mooney | i think that was self inflicted | |
| 15:11:19 | sean-k-mooney | you can actully unshleve i hvae tested that | |
| 15:11:47 | sean-k-mooney | so the nasty part of this bug is it appears to work but its subtely broken | |
| 15:11:54 | valleedelisle | sean-k-mooney, can we unshelve on a host with the same pci device in use? | |
| 15:12:07 | artom | valleedelisle, oh that's your upstream nick | |
| 15:12:09 | valleedelisle | valleedelisle, I think that the point of that bz is the pci device not being re-calculated | |
| 15:12:16 | valleedelisle | yeah dvd is already in use hehe | |
| 15:12:17 | sean-k-mooney | valleedelisle: no that will cause the libvirt error in the upstream bug | |
| 15:12:30 | sean-k-mooney | libvirt/qemu will cay the device is already in use | |
| 15:12:38 | sean-k-mooney | but if the pci device is not in use then yes | |
| 15:12:46 | artom | valleedelisle, 'dvd :No such nick/channel' | |
| 15:12:49 | valleedelisle | sean-k-mooney, yeah but shouldn't we recalculate pci device ? | |
| 15:12:55 | valleedelisle | artom, it's registered | |
| 15:12:57 | sean-k-mooney | we do | |
| 15:13:02 | artom | Bleah :( | |
| 15:13:03 | sean-k-mooney | and we claim it in the db | |
| 15:13:10 | sean-k-mooney | we just dont update the port profile | |
| 15:13:18 | sean-k-mooney | which is the bug | |
| 15:13:22 | valleedelisle | ack | |
| 15:13:58 | sean-k-mooney | i repodcued the bug manually on my sriov hardware at home and confirmed that i just did not have time to work on a fix a the time | |
| 15:15:49 | openstackgerrit | Merged openstack/nova master: Update master for stable/wallaby https://review.opendev.org/c/openstack/nova/+/783217 | |
| 15:39:01 | artom | sean-k-mooney, btw, in order to actually write the unshelve func test properly, I need to fix the Neutron fixture to go further than that KeyError | |
| 15:46:00 | gibi | sean-k-mooney: you will probably like this https://storyboard.openstack.org/#!/story/2008764 | |
| 15:46:26 | sean-k-mooney | gibi: well its on story borad but lets see | |
| 15:46:45 | sean-k-mooney | oh ya i think it has uses | |
| 15:47:22 | sean-k-mooney | ya preventing loops and orpans is something we woudl have to do | |
| 15:47:32 | sean-k-mooney | to mantain the DAG stucture | |
| 15:47:36 | gibi | sean-k-mooney: how can we make orphans? | |
| 15:47:48 | gibi | sean-k-mooney: loop check is already implemented | |
| 15:47:51 | sean-k-mooney | settign parent to None | |
| 15:48:04 | gibi | that does not orphan things that creates a new root provider | |
| 15:48:05 | sean-k-mooney | or a rp that does not exist | |
| 15:48:16 | sean-k-mooney | well it would be a root provider yes | |
| 15:48:22 | gibi | yeah, non existing RP needs to be rejected (an rejected already) | |
| 15:48:31 | sean-k-mooney | but if you did that to your bandwith RPs it woudl be kind of broken | |
| 15:48:51 | gibi | broken from nova an neutron perspective but not from placement perspective | |
| 15:48:55 | sean-k-mooney | yep i just commenting on jays comment you copied | |
| 15:49:01 | sean-k-mooney | well the TODO | |
| 15:49:12 | gibi | placement does not know the intention of the clients | |
| 15:49:13 | sean-k-mooney | gibi: yep it would be a logic error | |
| 15:49:20 | sean-k-mooney | but not invalid in general | |
| 15:49:31 | gibi | yepp from placement perspective creating a new root RP is valid | |
| 15:49:39 | sean-k-mooney | so used correctly i think its a useful feature | |
| 15:49:44 | gibi | yepp | |
| 15:50:06 | sean-k-mooney | i also think its slightly diffrent then reshaping | |
| 15:50:11 | gibi | it is | |
| 15:50:19 | gibi | reshape is to move allocations around | |
| 15:50:25 | gibi | this is to move RPs around :) | |
| 15:50:42 | sean-k-mooney | allocation and inventores and potentialy creating more or less RPs | |
| 15:50:50 | gibi | reshape does not create RPs | |
| 15:50:54 | sean-k-mooney | where as moving an RP is just that changing it postion in the grap | |
| 15:50:56 | gibi | but yes it move inventories and allocations | |
| 15:51:06 | sean-k-mooney | gibi: well it does not on the placment side | |
| 15:51:13 | sean-k-mooney | but our nova reshapes do | |
| 15:51:20 | gibi | nova creates RPs, and then reshape to those RPs | |
| 15:51:21 | sean-k-mooney | for example the vgpu reshpe | |
| 15:51:25 | sean-k-mooney | yep | |
| 15:51:29 | gibi | :) | |
| 15:51:49 | sean-k-mooney | we do multipel operation in the nova fucnitons that we incorreectly refer to as reshaping as a whole | |
| 15:52:04 | sean-k-mooney | but ya reshape in the placment api is a specific thing | |
| 15:52:11 | gibi | yepp | |
| 15:52:43 | sean-k-mooney | my original use case for this was moving pci device if we later added numa nodes | |
| 15:52:50 | sean-k-mooney | or vgpus | |
| 15:53:01 | gibi | yepp, I added that to the story as a reason | |
