| kata-irc-bot3 | <archana.m.shinde> zer0def just seeing this, I have not been able to replicate this, so would like to know details about your setup | 20:18 |
|---|---|---|
| zer0def | @archana.m.shinde arch-based, linux-hardened 5.3.13, qemu 4.1.1, let me quickly generate a log | 20:22 |
| kata-irc-bot3 | <archana.m.shinde> thanks zer0def | 20:25 |
| kata-irc-bot3 | <archana.m.shinde> what version of podman ? distro provided packages? | 20:25 |
| zer0def | happens both on 1.6.3 and git master | 20:26 |
| kata-irc-bot3 | <archana.m.shinde> ok | 20:26 |
| zer0def | gimme a second, i've apparently mis-symlinked a local build i was working on to cleanup the aur pkgbuild | 20:27 |
| kata-irc-bot3 | <archana.m.shinde> sure, take your time | 20:27 |
| kata-irc-bot3 | <archana.m.shinde> zer0def stepping away for a bit, would also appreciate if you could attach output of ` sudo kata-collect-data.sh` | 20:32 |
| *** gwhaley has quit IRC | 20:34 | |
| zer0def | @archana.m.shinde https://dpaste.de/8k5h/raw and https://dpaste.de/jZ8i/raw respectively | 20:48 |
| zer0def | to be fair, the archlinux repack is straight from f30 with just a few paths tweaks: https://raw.githubusercontent.com/zer0def/PKGBUILDs/kata-containers/PKGBUILD | 20:51 |
| kata-irc-bot3 | <archana.m.shinde> zer0def thanks. Can you send me the kata journal logs as well ? | 21:32 |
| kata-irc-bot3 | <archana.m.shinde> you will need to ``` sudo sed -i -e 's/^# *\(enable_debug\).*=.*$/\1 = true/g' /usr/share/defaults/kata-containers/configuration.toml sudo journactl | grep kata-runtime``` | 21:33 |
| *** igordc has quit IRC | 21:33 | |
| zer0def | @archana.m.shinde from just now: https://dpaste.de/oChO/raw | 21:38 |
| zer0def | nothing that the command execution log doesn't have | 21:38 |
| *** igordc has joined #kata-general | 21:39 | |
| zer0def | hnh… compared to a rooted podman container run, for rootless conmon returns -1 for the PID, which is obviously wrong | 21:43 |
| kata-irc-bot3 | <archana.m.shinde> zer0def yeah, the main issue is `mkdir /var/run/netns: permission denied` | 21:46 |
| kata-irc-bot3 | <archana.m.shinde> will have to see where and why that was invoked | 21:46 |
| kata-irc-bot3 | <archana.m.shinde> zer0def was this with host networking, whats the podman command that you ran? | 21:51 |
| zer0def | `podman --log-level debug run --runtime kata --net none -ti alpine:edge /bin/sh` | 21:53 |
| kata-irc-bot3 | <archana.m.shinde> can you try without `--net none` | 21:53 |
| kata-irc-bot3 | <archana.m.shinde> and give me the kata logs | 21:53 |
| zer0def | uh, read again? :) | 21:53 |
| kata-irc-bot3 | <archana.m.shinde> so, `podman --log-level debug run --runtime kata -ti alpine:edge /bin/sh` | 21:54 |
| zer0def | this error actually turns into: `time="2019-11-26T22:51:54+01:00" level=debug msg="ExitCode msg: \"open /var/run/netns/cni-aeeccd84-64b1-2ed6-7187-45a72fb63e37: permission denied: oci runtime permission denied error\""` once /var/run/netns is created by, for example, creating a rooted container | 21:54 |
| zer0def | without `--net none` i personally consistently get: `time="2019-11-26T22:54:46+01:00" level=debug msg="ExitCode msg: \"rpc error: code = unknown desc = open /run/kata-containers/sandbox/resolv.conf: no such file or directory: oci runtime command not found error\""` | 21:55 |
| kata-irc-bot3 | <archana.m.shinde> oh ok | 21:56 |
| kata-irc-bot3 | <archana.m.shinde> can I ask you to paste the entire sequence of logs like you did earlier | 21:56 |
| kata-irc-bot3 | <archana.m.shinde> I want to see how far it gets | 21:56 |
| zer0def | for `--net none` you're probably looking at https://github.com/containers/libpod/blob/master/libpod/networking_linux.go#L395 | 21:57 |
| zer0def | sure looks like a permissions issue, let me just slap on go+w on it, see what happens | 21:58 |
| kata-irc-bot3 | <archana.m.shinde> yeah, I dont want to look into --net=none case right now | 21:58 |
| kata-irc-bot3 | <archana.m.shinde> I am interested in the one without it | 21:59 |
| zer0def | you don't have to, errors out the same way with /run/kata-containers/sandbox/resolv.conf | 21:59 |
| zer0def | actually, sorry, I confused the commands - once I make /var/run/netns go+w, the container starts | 22:01 |
| zer0def | `podman --log-level debug run --runtime kata -ti alpine:edge /bin/sh` → https://dpaste.de/bHiu/raw | 22:02 |
| zer0def | to clear up: when i run *with* `--net none` *and* 0777 on /var/run/netns, the container starts | 22:04 |
| kata-irc-bot3 | <archana.m.shinde> ok | 22:05 |
| kata-irc-bot3 | <archana.m.shinde> that seems to be a bug on the podman side for --net=none | 22:06 |
| zer0def | it does, will bring it up there later | 22:06 |
| *** MartinXu41 has joined #kata-general | 22:23 | |
| zer0def | journal log for `podman --log-level debug run --runtime kata -ti alpine:edge /bin/sh`: https://dpaste.de/4jsT/raw I'm sort of curious about the warning for devices.json on line 19 | 22:25 |
| zer0def | actually, nevermind. | 22:26 |
| kata-irc-bot3 | <archana.m.shinde> yeah thats a benign warning | 22:29 |
| MartinXu41 | @all looks like the Slack link does not work. Some one can tell me whether Slack is still avaiable for Kata? thanks! | 22:30 |
| kata-irc-bot3 | <archana.m.shinde> it looks like it was able to start the VM successfully, error seems to be while cleanup | 22:30 |
| kata-irc-bot3 | <archana.m.shinde> nvm | 22:32 |
| zer0def | looks more like line 45 is causing the issue, which means it's an error bubbling up from the agent… and @james.o.hunt just trips on line 43 instead | 22:32 |
| zer0def | possibly s/43/41/ | 22:34 |
| kata-irc-bot3 | <archana.m.shinde> could be | 22:43 |
| kata-irc-bot3 | <archana.m.shinde> seems there are some missing logs from the agent itself | 22:43 |
| kata-irc-bot3 | <archana.m.shinde> `sudo journalctl | grep kata` may provide something useful | 22:44 |
| zer0def | https://dpaste.de/HNzx/raw starting from line 105 upwards | 22:50 |
| zer0def | specifically the "&Empty{XXX_unrecognized:[],}" response | 22:50 |
| zer0def | funny thing, running `sudo podman --log-level debug run **--shm-size 0** --runtime kata -ti alpine:edge /bin/sh` achieves the same result, but that's rather obvious from the log | 22:57 |
| zer0def | ok, that response I've drawn attention to doesn't differ from a successful rooted launch, however the rooted container's agent starts correctly (as long as there's an shm), compared to rootless | 23:02 |
| zer0def | meanwhile, I'm clocking out, let me know how else I could be of help, will get to it the first opportunity I'll get | 23:06 |
| kata-irc-bot3 | <archana.m.shinde> sure zer0def, will let you know | 23:09 |
| kata-irc-bot3 | <archana.m.shinde> thanks for your help | 23:09 |
