Ugglabauzas, short msg to tell you that I have added a point about virtiofs next features. It would be great to have a short session to discuss that especially with Adri2000 who could be a potential user.09:43
Ugglabauzas, I know it is maybe a bit early, but I guess it could help me to figure out what will be the next topics to address.09:44
bauzasUggla: yeah, np, for sure09:51
Ugglabauzas, \o/09:52
bauzasUggla: as you can see, I eventually didn't really created an agenda, we'll lookup the topics one after the other09:52
bauzaseach one after the other one*09:52
Ugglabauzas, maybe for this one it could be good to have a slot. I guess it will be easier to Adri2000 to join.09:53
Ugglabauzas, maybe that could stand right after the manila one ?09:54
bauzasUggla: in general I ping the courtesy ping list before a topic, to ask them when they have time to discuss09:55
Ugglabauzas, I'm saying that because Adri2000 told me, he will join the manila session. Just to let you know, if it could help you.10:01
bauzasI can discuss with Adrien, np10:01
Ugglabauzas, good so now I jump back to the virtiofs stuff to rework the interfaces because you dislike them. ;)10:04

zigobauzas: When live-mig fails, I have this in my syslog: https://paste.opendev.org/show/b2sqj6SSBsGOdN2D4phz/14:21
zigo(sorry, didn't noticed it yesterday)14:21
zigoDoes this help a little ?14:21
kashyapzigo: Randomly noticing it here.  That's a strange error I've never seen14:24
kashyapinternal error: qemu unexpectedly closed the monitor: 2023-03-24T14:19:28.554056Z qemu-system-x86_64: VQ 2 size 0x80 < last_avail_idx 0x83d9 - used_idx 0x014:24
zigokashyap: Yeah, this feels like a libvirt / qemu bug, rather than an issue in Nova...14:26
kashyapThe error is definitely coming from QEMU14:27
kashyapzigo: Are you hitting it consistently?  What QEMU/libvirt versions?14:27
kashyapCan you post the full guest QEMU invocatoin?14:27
kashyapAll of 'em preferably in a bug (if it's reproducible) :-)14:27
zigoqemu: 1:5.2+dfsg-11+deb11u214:28
zigolibvirt: 7.0.014:28
zigo(this is a plain Debian Bullseye...)14:28
zigokashyap: When the VM can't live-migrate, it goes back to state MIGRATING to ACTIVE, and I can make it happen again, yes.14:28
zigokashyap: When the VM can't live-migrate, it goes back from state MIGRATING to ACTIVE, and I can make it happen again, yes.14:29
kashyapSame versions on source and destination hosts?14:29
zigoYeah.14:29
zigoWhat's weird is that, on each compute, we run maybe 100+ VMs, and each time, 2 or 3 are stuck, refusing to migrate this way.14:29
kashyapHm, these bugs need a more systematic debugging.  Please file a bug.  But it might very well be fixed upstream (I know)14:31
kashyapSee this, for example: https://www.mail-archive.com/qemu-devel@nongnu.org/msg441182.html14:31
kashyapA similar error)14:31
zigoYeah.14:33
zigoIs there a qemu IRC channel?14:33
kashyapYes14:35
kashyap#qemu, OFTC14:35
zigoWill try.14:35
bauzastmazur: so you want to have a cross-project session for Horizon ?16:03
tmazurbauzas: it would be nice, but we do not insist. We would like to just clarify things about potential implementation python bindings. It's pretty clear that osc-placement is not the right place for them anyway, and you pointed it in the etherpad. Is something like python-placementclient coming in any reasonable future?16:08
vishalmanchandabauzas: hello, Can we have a 20-25 mins nova-horizon cross-project session on Tuesday, March 28 at 15 UTC?16:16
