| kata-irc-bot | <xwlpt> Does anyone met this issue? https://github.com/kata-containers/kata-containers/issues/28#issuecomment-459351456 | 14:44 |

| kata-irc-bot | <eric.ernst> What’s your CRI? | 15:50 |
| kata-irc-bot | <eric.ernst> Implementation, @xwlpt | 15:50 |
| kata-irc-bot | <eric.ernst> I saw this yesterday as well. | 15:50 |
| kata-irc-bot | <eric.ernst> It is painful. | 15:51 |
| kata-irc-bot | <graham.whaley> another sighting maybe reported here as well https://github.com/kata-containers/runtime/issues/1203 | 15:55 |
| kata-irc-bot | <eric.ernst> I see w and w out vsock | 15:55 |
| kata-irc-bot | <eric.ernst> This is in a nested vm | 15:55 |
| kata-irc-bot | <eric.ernst> I don’t see it when running in the L1 | 15:55 |
| kata-irc-bot | <eric.ernst> (Only test docker in L1, and k8s w containerd 1.2.2 in L2) | 15:56 |
| kata-irc-bot | <eric.ernst> ..,thought it worked w crio though... will dig in this today... | 15:57 |
| kata-irc-bot | <eric.ernst> @james.o.hunt what distro for you? | 15:59 |
| kata-irc-bot | <eric.ernst> And, bare metal, or..? | 16:01 |
| gwhaley | @eric.ernst - I think @jodh may have to drop in a bit - on another channel he confirmed bare metal, but not what distro | 16:04 |
| kata-irc-bot | <james.o.hunt> baremetal 18.04 fully updated. @sebastien.boeuf, @julio.montes - what distros are you on? | 16:04 |

| devimc | jodh, eernst ubuntu with 4.18 works | 17:11 |
| devimc | seem like the problem is the kernel 4.15 | 17:12 |
| kata-irc-bot | <eric.ernst> I have it working fine on Linux version 4.15.0-1036-azure | 17:13 |
| kata-irc-bot | <eric.ernst> And, when I see the issue, it is irrespective of vsock. | 17:13 |
| devimc | eernst, kata-runtime kata-env | grep -i vsock | 17:15 |
| devimc | can you run this command? | 17:15 |
| kata-irc-bot | <eric.ernst> no proxy running here. | 17:17 |
| kata-irc-bot | <eric.ernst> ``` /opt/kata/bin/kata-qemu kata-env | grep -i vsock UseVSock = true SupportVSocks = true ``` | 17:18 |
| kata-irc-bot | <eric.ernst> ``` $ cat /proc/version Linux version 4.15.0-1036-azure (buildd@lcy01-amd64-006) (gcc version 7.3.0 (Ubuntu 7.3.0-16ubuntu3)) #38-Ubuntu SMP Fri Dec 7 02:47:47 UTC 2018 ``` | 17:18 |
| devimc | uhhm ok, i guess it's a problem with the generic kernel | 17:19 |
| kata-irc-bot | <eric.ernst> why do we think its the kernel? I missed some context. | 17:21 |
| devimc | eernst, https://github.com/kata-containers/runtime/issues/1203 | 17:22 |
| kata-irc-bot | <eric.ernst> see this too: https://github.com/kata-containers/kata-containers/issues/28#issuecomment-459351456 | 17:23 |
| kata-irc-bot | <eric.ernst> i'd liek to reproduce and gather the qemu.logs like @xwlpt did. | 17:24 |
| devimc | 4.15.0-43.generic.x86_64 | 17:24 |
| kata-irc-bot | <eric.ernst> if you have the failure there, can you please do the same? | 17:24 |
| devimc | :S | 17:24 |
| devimc | eernst, https://github.com/kata-containers/runtime/issues/1203#issuecomment-459425044 | 17:24 |
| kata-irc-bot | <eric.ernst> Yeah; can you gather output from qemu as well? | 17:25 |
| kata-irc-bot | <eric.ernst> this is FUN! | 17:25 |
| kata-irc-bot | <eric.ernst> When I see the issue, i'm not using VSOCK. | 17:25 |
| kata-irc-bot | <eric.ernst> Let me get my failing VM back up though first... | 17:25 |
| devimc | eernst, I think this is a different problem | 17:25 |
| devimc | that issue was found in ubuntu 14.04 kernel 3.18.118 | 17:27 |
| *** sameo has joined #kata-dev | 17:31 | |
| kata-irc-bot | <eric.ernst> that last comment was? | 17:33 |
| kata-irc-bot | <claire> Hey there - I’d love to add some recorded Kata demos to the website refresh that I’m working on. So if you have any available that you’d be willing to share, please send me the links or files. Thanks! | 17:34 |
| kata-irc-bot | <eric.ernst> @julio.montes : ``` clear@clr-01 /usr/lib/systemd/system $ sudo docker run --runtime=kata-runtime -it alpine sh docker: Error response from daemon: OCI runtime create failed: Failed to check if grpc server is working: rpc error: code = Unavailable desc = transport is closing: unknown. clear@clr-01 /usr/lib/systemd/system $ cat /proc/version Linux version 4.14.81-413.lts (mockbuild@kojibld02) (gcc version 8.2.1 20180502 (Clear Linux OS | 17:35 |

| kata-irc-bot | <eric.ernst> not using vsock | 17:35 |
| kata-irc-bot | <eric.ernst> Unfortunately I can't get the qemu log. I tried just adding a wrapper around our QEMU call, ala: ``` #!/bin/bash /usr/bin/kata-qemu-lite-system-x86_64 -D /tmp/qemu.log "$@" ``` | 17:39 |
| davidgiluk | eric.ernst: I've never seen -D - just use 2> /tmp/qemu.log | 17:40 |
| kata-irc-bot | <eric.ernst> same story. | 17:42 |
| kata-irc-bot | <eric.ernst> The qemu process is still hanging around there. | 17:42 |
| kata-irc-bot | <eric.ernst> Is there a more polite way to kill that'd get me a log... | 17:42 |
| davidgiluk | odd | 17:43 |
| devimc | eernst, might be the journal can give you more information | 17:43 |
| kata-irc-bot | <eric.ernst> Not yet, anyway -- I just get the gRPC timeout. | 17:44 |
| devimc | with serial port | 17:44 |
| devimc | that's weird | 17:45 |
| kata-irc-bot | <eric.ernst> I can put your ssh key in if you want to poke/tmux on | 17:45 |
| gwhaley | @eric.ernst, @devimc, @sboeuf - if you make progress on the whole gRPC hang up stuff, and/or have things left to try etc., make sure to leave some breadcrumbs (on Issue would be best maybe) so if jodh and I need to pick something up in the morning we can... | 18:00 |
