johnsomHi Nova community. The Octavia team is seeing some strange behavior with libvirtd. https://storage.gra.cloud.ovh.net/v1/AUTH_dcaab5e32b234d56b626f72581e3644c/zuul_opendev_logs_c77/759973/3/check/octavia-v2-dsvm-scenario/c77fe63/controller/logs/libvirt/libvirtd_log.txt16:19
johnsomWarning, that is a 136MB log file16:19
johnsomIt seems to go into some sort of tight loop:16:20
lyarwoodops, opening that in chrome was a mistake16:20
johnsomhttps://www.irccloud.com/pastebin/c6NcVeeF/16:20
johnsomAlmost 90% of that log file is the above16:20
lyarwoodkashyap: ^ if you have time16:20
lyarwoodring any bells?16:21
*** hamalq has quit IRC16:21
johnsomEventually it seems to finally exit. The issue we have is while it's stuck in this loop other VMs are not going ACTIVE in nova, so causes all sorts of timeouts.16:21
kashyaplyarwood: Just a sec; lost in two other convo threads :-(16:21
lyarwoodkashyap: np16:22
*** hamalq has joined #openstack-nova16:22
kashyapjohnsom: As a quick question - in what scenario do you see that?16:22
lyarwoodjohnsom: might be useful to write that up in a nova bug that kashyap can follow up with16:22
lyarwoodops sorry16:22
kashyapjohnsom: That "End of file" ... simply means libvirt lost connection to QEMU16:22
johnsomIt appears that nova was trying to delete the instance16:22
kashyaplyarwood: No worries; a bug also helps - as a record16:22
johnsomHere is a chunk of the log right before the loop:16:23
johnsomhttps://www.irccloud.com/pastebin/LRErlmPf/16:23
kashyapjohnsom: Yeah, but that doesn't tell us what events led to that (they're in the 130MB log file).  :-) Is this reproducible?16:26
johnsomIt is reproducible, but intermittent. Not every job triggers it.16:27
gibi#nova now refresh connection_info / avoid storing stale connection_info in Nova16:28
johnsomWe are seeing it while we run our scenario test suites.16:28
kashyapjohnsom: A write-up in a bug would be nice to track.  Along w/ a description of a test case that's hitting it.  (I'm almost out of neurons tonight, and my mind now has the "thousand yard stare")16:30
johnsomYeah, I'm writing one up. I will link to the long, but I don't think I should attach it given it's size, so it will expire off the object store.16:31
johnsomI will paste in a few snippets.16:31
