| 19:03:59 | efried_nomnom | Also sean-k-mooney we wouldn't know how to do that offhand. But since you've volunteered to guide us.... :) | |
| 19:04:06 | cfriesen | I'm trying to figure out if a bug is in nova or libvirt/qemu. Do we have any functional/tempest tests of live migration with a config drive and an attached cinder volume? | |
| 19:04:45 | Roamer` | hmm, if mriedem is really on vacation, could I interest any of you in taking a quick look at https://review.openstack.org/140733/ - the StorPool libvirt volume attachment driver? :) The Cinder and os-brick support is in, and Nova's requirements.txt has a dependency on the new version of os-brick now. | |
| 19:05:31 | Roamer` | of course, "leave it till he gets back" might also be kind of reasonable... although it may be cutting it a bit too close to the January 25th deadline | |
| 19:06:34 | sean-k-mooney | efried_nomnom: sure im happy to help. its not a huge amount of work to do but it means you dont have to submit patches to nova to take advantage of things like ovs now support jumbo frames with datapath x or other network backend specific features | |
| 19:07:15 | efried_nomnom | sean-k-mooney Thanks in advance | |
| 19:08:25 | sean-k-mooney | efried_nomnom: other then requireing a powerpc system is there any other requirement to be able to deploy powervm. e.g. is it opensouce? | |
| 19:10:10 | efried_nomnom | sean-k-mooney As long as "having a POWER system" includes relevant licensing (e.g. for VIOS), no other requirements I believe. Everything else is free (though not all of it is open source). | |
| 19:11:21 | sean-k-mooney | efried_nomnom: hum ok i was wondering if i could emulate PPC under kvm and in stall powervm hyperviors under something like ubunut but i guess not | |
| 19:11:30 | cfriesen | melwitt: do you know what the fix was for https://bugzilla.redhat.com/show_bug.cgi?id=1394964 (I'm guessing "mwitt@redhat.com" is you...) | |
| 19:11:31 | openstack | bugzilla.redhat.com bug 1394964 in openstack-nova "Live migration with config-drive fails with InvalidSharedStorage error" [High,Closed: errata] - Assigned to mwitt | |
| 19:11:52 | efried_nomnom | sean-k-mooney No, fraid not. | |
| 19:12:23 | efried_nomnom | sean-k-mooney I mean, if you *could* actually emulate POWER (which isn't PowerPC, btw) then I imagine you could do that. | |
| 19:13:00 | efried_nomnom | sean-k-mooney But emulating POWER is very, very hard. There is/was a project around here to do it, but I don't think it's up to date; and it's dogggggg slow. | |
| 19:13:15 | sean-k-mooney | oh i did not know they were different. PPC is ibm right is POWER openPOWER | |
| 19:13:37 | efried_nomnom | I'm not sure what the status of ppc is actually. | |
| 19:13:54 | efried_nomnom | And POWER is *almost* openPOWER. | |
| 19:14:09 | melwitt | cfriesen: yes, that is me. looking ... | |
| 19:14:20 | efried_nomnom | I think openpower is a way for not-IBM to build POWER-compatible systems. | |
| 19:15:12 | efried_nomnom | But I'm totally not a terminology/marketing guy. I just try to write as much code as possible. | |
| 19:16:25 | cfriesen | melwitt: maybe bc4b9980f ? | |
| 19:16:26 | sean-k-mooney | til well i shoudl be able to help in anycase. there is a lot you can do with unitest to fake things out + there is the IBM PowerVM CI so if you remind me/ i get time i might take a go at it but not before the PTG/end of Q1 | |
| 19:19:07 | melwitt | cfriesen: so it was fixed by having https://review.openstack.org/#/c/227278 and removing VIR_MIGRATE_TUNNELLED from the block_migration_flag in nova.conf | |
| 19:19:29 | melwitt | and I think config drive has to be vfat also | |
| 19:20:49 | cfriesen | melwitt: okay, was wondering about that last part. we're still (in Pike) hitting issues with iso9660 config drives and boot-from-volume on a compute node with local storage. | |
| 19:21:45 | cfriesen | melwitt: specifically with block-live-migrating such instances | |
| 19:22:03 | cfriesen | I'm trying to see if it's something we broke or an upstream issue. | |
| 19:22:07 | melwitt | cfriesen: yeah, I can't remember the context now but if you dig into the libvirt driver code there are a lot of conditions that have to be met before live block migration will work, and if you have a config drive, that's local storage so has to be a live BLOCK migration | |
| 19:22:43 | melwitt | you can't have the tunneling but I don't remember why | |
| 19:23:48 | cfriesen | melwitt: that part I know...tunnelling prevents the "block migrate some disks but not others" behaviour in libvirt | |
| 19:23:56 | melwitt | oh, okay. cool | |
| 19:24:12 | melwitt | now I know then :) | |
| 19:29:10 | melwitt | cfriesen: I know that in the past iso9660 config drives couldn't be live migrated, I don't know when/if that was fixed. based on the absence of 'vfat' in the pike code I'm guessing it was fixed | |
| 19:30:12 | melwitt | I just updated the BZ to make a lot of the comments public that didn't need to be private | |
| 19:30:32 | melwitt | in case that might help ppl that happen upon it | |
| 19:36:37 | melwitt | looks like iso9660 migration was enabled by https://review.openstack.org/#/c/234659 | |
| 20:09:20 | openstackgerrit | Merged openstack/nova master: Rename block_device_info_get_root https://review.openstack.org/529028 | |
| 20:21:50 | sean-k-mooney | jaypipes: looks like the gate is happy with it. https://review.openstack.org/#/c/534307/2 once that is merged im happy to go with a 1.8.1 release. | |
| 20:24:07 | jaypipes | sean-k-mooney: question... why don't we just straight revert the pyroute patch from rodolfo>? | |

| 20:47:51 | sean-k-mooney2 | jaypipes rodolfo patch also introduces the infra for functional testing and deduplicates the logic from linux bridge plugin and ovs | |
| 20:48:52 | sean-k-mooney2 | So i would like to keep that and just delay moving to pyroute2 until a new release is out | |
| 20:49:52 | jaypipes | sean-k-mooney2: ok... | |

| 21:42:50 | matrohon | sean-k-mooney: hi | |
| 21:45:33 | cfriesen | melwitt: mdbooth: it turns out that if you have an instance with an iso9660 config drive and a ceph-backed attached cinder volume, then block-live-migration fails in libvirt with "qemuMigrationPrecreateStorage:463 : Operation not supported: pre-creation of storage targets for incremental storage migration is not supported". With iscsi-backed cinder volumes it works fine. | |
| 21:46:51 | cfriesen | At least in our code....still trying to track down whether we broke something or if it's upstream. | |

| 09:42:10 | kashyap | stephenfin: Heya, when you get a moment, mind taking a gander at this (one of the use cases is right in your wheel house)? https://review.openstack.org/#/c/534384/ -- "[WIP] libvirt: Allow to specify granular CPU feature flags" | |
| 09:42:29 | kashyap | stephenfin: It's still WIP, I need to fix the 11 or so broken tests | |
| 09:42:58 | kashyap | But thought I'd put it out there, as we should it'll alleviate the performance impact that the recent "Meltdown" CVE fixes cause. | |
| 09:43:11 | kashyap | The commit message tells it all (I mean, all) :-) | |
| 09:47:06 | stephenfin | kashyap: Sounds good | |
| 09:48:18 | bauzas | stephenfin: just in case, you could also be interested in https://review.openstack.org/#/c/528832/ | |
| 09:48:20 | kashyap | stephenfin: Just to note --- next two days I'm a bit sporadic in my availability, Friday night, I'lll be back home | |
| 09:48:31 | bauzas | stephenfin: ;) | |
| 09:56:42 | BKaminski | There any etiquette on adding someone as a reviewer to a commit if you know they know that code well? | |
| 09:58:03 | kashyap | BKaminski: Sure, it's fine. | |
| 09:58:28 | BKaminski | Alrighty, thanks :) | |
| 09:59:38 | kashyap | BKaminski: E.g. sometimes I run this command: git shortlog -nse nova/$File-of-Interest | |
| 09:59:46 | kashyap | To get a sense of who might know a certain area | |
| 10:00:03 | BKaminski | Ah that does maek sense | |
| 10:00:03 | kashyap | Then check if they're still active, and add them to Cc. | |
| 10:00:28 | kashyap | (I do it for mailing lists based projects mostly, as it requires explicit Cc) | |
| 10:00:47 | kashyap | But obviously, the trick applies for any Git-based project | |
| 10:00:58 | BKaminski | That makes sense.. i'll give it a go just to get it on a couple of peoples radars that I know worked on this code, since XenAPI code is kind of hard to catch a reviewer on I think :D | |
| 10:01:42 | kashyap | Yup | |
| 10:04:00 | BKaminski | Last commit into .Xenapi was Aug 2017 .. whew... | |
| 10:05:43 | BKaminski | OH nevermind.. December.. i apparently had a temporary brain to vision disease there hehe | |
