| 04:14:10 | hungnt1 | i have 1 openstack cluster run on production. | |
| 04:14:14 | hungnt1 | i have 1 openstack cluster run on production. | |
| 04:14:18 | hungnt1 | all compute run CPU Intel Xeon Gold 6126 and fixed CPU model for VM is Skylake-Server | |
| 04:14:38 | hungnt1 | now i have 10 new server run CPU Intel Xeon Gold 6330 | |
| 04:14:54 | hungnt1 | How can I check the new CPU compatibility with SkyLake-Server for migration VM ? | |
| 04:14:59 | hungnt1 | can anyone help me ? | |
| 04:23:59 | sean-k-mooney[m] | the 6126 is skylake and 6330 are icelake | |
| 04:24:33 | sean-k-mooney[m] | if you use a custom cpu model of skulake-server on all host they should be compatible | |
| 04:25:13 | sean-k-mooney[m] | you will need to set cpu_mode=custom cpu_model=skylake-server in the libvirt section of the nova.conf | |
| 04:25:24 | sean-k-mooney[m] | rather then relying on the default host-model | |
| 04:25:38 | hungnt1_ | now, my config is cpu_model=skylake-server | |
| 04:25:42 | sean-k-mooney[m] | you can check compatibality using libvirt | |
| 04:25:54 | sean-k-mooney[m] | yep that should work | |
| 04:26:48 | sean-k-mooney[m] | the simplest way yo check really is to just deploy the nodes and try the migration honestly but it should work | |
| 04:27:33 | hungnt1_ | i need check compatibility before order server | |
| 04:29:06 | hungnt1_ | model ? | |
| 04:29:06 | hungnt1_ | need confirm 6330 model contain all feature flags of skylake-server | |
| 04:33:02 | hungnt1_ | where can get list feature flag of SkyLake and IceLake | |
| 04:33:40 | sean-k-mooney[m] | normally i would suggest downloading the datasheet form intel https://ark.intel.com/content/www/us/en/ark/products/212458/intel-xeon-gold-6330-processor-42m-cache-2-00-ghz.html | |
| 04:33:57 | sean-k-mooney[m] | but it does not seam to be avaialable for that model | |
| 04:35:57 | hungnt1_ | i cann't find it too | |
| 04:36:55 | hungnt1_ | makes me not 100% sure about compatibility | |
| 04:36:56 | sean-k-mooney[m] | you could compare the cpu models in libvirt/qemu | |
| 04:37:31 | sean-k-mooney[m] | i.e. assert the icelake model is a superset of the skylake one | |
| 04:38:10 | sean-k-mooney[m] | the abstract cpu models are intended too allow this type of compatiblity | |
| 04:38:40 | sean-k-mooney[m] | but other then that im not sure there is much else we can suggest | |
| 04:39:47 | hungnt1_ | maybe i need contact Intel to get list feature | |
| 04:39:57 | hungnt1_ | and make compareration | |
| 04:41:43 | sean-k-mooney[m] | https://paste.opendev.org/show/811678/ | |
| 04:42:29 | hungnt1_ | oh | |
| 04:42:34 | hungnt1_ | tks u | |
| 04:42:51 | hungnt1_ | tôi sẽ kiểm tra, nó hữu ích | |
| 04:42:54 | hungnt1_ | i will check, it helpful | |
| 04:43:33 | sean-k-mooney[m] | no worries those xmls basicaly define the abstrack cpu models used or at least a semi human readable version of them | |
| 04:45:06 | sean-k-mooney[m] | the only think im not sure about is <feature name='intel-pt' removed='yes'/> everything else looks like a superset | |
| 04:47:10 | sean-k-mooney[m] | ah it processor tracing | |
| 04:47:12 | sean-k-mooney[m] | https://bugzilla.redhat.com/show_bug.cgi?id=1853972 | |
| 04:47:28 | sean-k-mooney[m] | looks like it was never implemented in qemu/kvm | |
| 06:33:26 | hungnt1_ | in libvirt v4.5.0, it have <feature name='intel-pt'/> in Icelake map | |
| 06:35:19 | hungnt1_ | https://www.diffchecker.com/XXMDm5kL | |
| 06:35:57 | hungnt1_ | i had diffcheck in ver 4.5.0 | |
| 10:39:30 | gibi | hi! I need a second core (other that bauzas) on the bugfix https://review.opendev.org/c/openstack/nova/+/820549 | |
| 11:26:27 | stephenfin | gibi: Done. Nice work | |
| 11:26:36 | gibi | stephenfin: thanks a lot! | |
| 11:27:45 | gibi | stephenfin: this might be intresting to you as well https://review.opendev.org/c/openstack/nova/+/821423 but it is not urgent as I have to fix tempest first | |
| 11:29:59 | stephenfin | gibi: Looking. I'm good on https://review.opendev.org/c/openstack/nova/+/766771 too. I know I originally wrote it, but that was ages ago and I'd forgotten about it so it's basically someone else's code now, heh | |
| 11:31:11 | gibi | yeah, it is a long story. funnily we got hit by it downstream so suddenly it got prioritized up on my list | |
| 11:31:44 | stephenfin | I think it was a downstream bug that caused me to work on that originally too, but I can't really be sure at this point | |
| 11:31:45 | gibi | but the parallel tempest execution actually triggers the bug and as soon as I started rejecting it tempest started to fail randomly | |
| 11:32:03 | gibi | so now I have a nice task to fix up tempest | |
| 11:32:15 | gibi | hence https://review.opendev.org/c/openstack/tempest/+/821732 | |
| 12:29:28 | sean-k-mooney | gibi: it kind of looks like it deadlocked | |
| 12:29:59 | gibi | sean-k-mooney: it has issues with the serial decorator itself as well. I'm troubleshooting locally | |
| 12:44:18 | sean-k-mooney | gibi you know looking at the decorator you could justr set __serial=True in the defition of the subclasses that should be serial too | |
| 12:44:34 | gibi | sean-k-mooney: sure, that is an alternative to the decorator | |

| 12:56:09 | gibi | sean-k-mooney: it appears that I should not rely on __serial as the __ makes is special from attribute lookup perspective | |
| 12:56:45 | sean-k-mooney | oh yes __ at the start alters name mangaling | |
| 12:58:16 | gibi | I knew I hit this before but I alway forget | |
| 12:59:17 | sean-k-mooney | gibi: i woudl just make it all UPPERCASE and remvoe the undersocres | |
| 12:59:44 | sean-k-mooney | like the class constants we have in the func test for api version and such | |
| 13:26:22 | sean-k-mooney | bauzas: elodilles: this was rebased https://review.opendev.org/c/openstack/nova/+/816883 can you +w to get it moving again | |

| 13:36:29 | elodilles | sean-k-mooney: done | |
| 13:36:40 | sean-k-mooney | elodilles: thanks | |
| 13:36:49 | elodilles | no problem :) | |
| 13:37:47 | sean-k-mooney | we had some downstream interest in it so just wanted to relay it upstream | |
| 14:00:11 | erlon | sean-k-mooney: hey, can you get some time to review https://review.opendev.org/c/openstack/nova/+/821840? Its the regression test for https://review.opendev.org/c/openstack/nova/+/815324 | |
| 14:00:31 | erlon | sean-k-mooney: please let me know if this is what you were thinking | |
| 14:01:21 | erlon | also, I need a piece of advice. I cant make it work, and it seems that the mock I'm using is just not mocking. I tried several ways, one is commented | |
| 14:37:54 | sean-k-mooney | erlon: not quite. you seam to be trying to create the reguression test more or less form scratch | |
| 14:38:41 | sean-k-mooney | erlon: i would have started by using one of our libvirt funtal test case base classes | |
| 14:39:07 | sean-k-mooney | also functional test should not really be mocking the way this is | |
| 14:39:18 | sean-k-mooney | this is closer to a unit test | |
| 14:40:35 | sean-k-mooney | erlon: so i proably should have started form 1897483 | |
| 14:40:40 | sean-k-mooney | * https://github.com/openstack/nova/blob/master/nova/tests/functional/libvirt/base.py#L31 | |
| 14:41:14 | sean-k-mooney | or from integrated_helpers._IntegratedTestBase | |
| 14:41:37 | sean-k-mooney | if it was not a libvirt specific issue | |
| 14:42:59 | sean-k-mooney | erlon: this is an example live migration functional test | |
