sgordonis there still an irc channel somewhere for clear containers that i should ask clear specific questions on or is that fair game here?13:43
sgordonim trying to work out if there are centos packages for the runtime somewhere that pull in https://github.com/clearcontainers/runtime/issues/73013:44
*** coolsvap has quit IRC13:44
sgordonor more specifically https://github.com/containers/virtcontainers/pull/42813:44
gwhaleyhi sgordon - there is a #clearcontainers still - but you will likely find all the same folks here. /cc jcarlosv jodh - do you know the answer to this one?13:45
gwhaleyand ^^ eocardon13:46
sgordoni can go build it myself it would just save me a heap of time not to (+ i want to document something i can hand to others for kicking the tyres)13:46
gwhaleysgordon: I expect we have the packages up on the OBS - I just don't have a link to hand, but the others might (but let me also go search a little...)13:46
gwhaleysgordon: if you go to the clearcontainers/packaging repo you will find the links to the obs repos on the front page there13:49
gwhaleyI can't fling you a link, as it looks like my link to github from this machine is down! :-/13:49

sgordonyeah, i was using http://download.opensuse.org/repositories/home:/clearcontainers:/clear-containers-3/RHEL_7/ but based on behavior i dont think it has this fix vendored in13:52
gwhaleyhi sgordon: (phew, long thread on that Issue....) - ah, I remember that. Yes, that looks like (if it is the same issue) that it was fixed in vc, and I'm pretty sure we should have re-vendored since then. hmmm....13:56
jodhsgordon: the fix is in the runtime fwics. Please can you raise an issue (https://github.com/clearcontainers/runtime/issues/new) pasting in the output of `cc-collect-data.sh` as explained in the issue template.13:56
gwhaleythe folks who might know or who were involved are probably still asleep right now ;-), but I think they have not gone off for the festive break. yet13:57
gwhaleyah, OK - that was going to be my next thing - if @ jcarlosv cannot confirm the revendor/packaging and @amsinde (not online right now) could not remember, then ping that ticket or probably better open a new one to make13:57
gwhaleysure it is the same thing or not - thx!13:57
jodhsgordon: could you also confirm on the issue whether you can create a Clear Container if you _don't_ use docker's --device= or --volume=.13:58
sgordonjodh, im actually just trying to run the basic example `sudo docker run -ti fedora bash14:03
jodhsgordon: oh wow, that should definitely work ;)14:04
sgordonwhich results in a "hook error" and level=info msg="Device has not been passed to the container" device=/dev/fuse source=virtcontainers subsystem=device"14:04
sgordonbased on the journalctl for the runtime14:04
sgordonanyway i am going to hose this one and start over i spent too much time poking it to try and get past this yesterday to be sure it is clean enough to call a reproducer14:05
jodhsgordon: did you follow https://github.com/clearcontainers/runtime/blob/master/docs/centos-installation-guide.md exactly? If so, please do raise an issue and attach the generated `typescript` so we can see if something went wrong at install time.14:08
jodhsgordon: sorry, I've just seen that you are specifically talking about RHEL - we don't have an install guide for RHEL as CentOS and RHEL are different in more than name ;) See https://github.com/clearcontainers/runtime/issues/46314:12
jodhsgordon: https://github.com/clearcontainers/runtime/pull/372 for more of the gory details.14:14
jodhHi jbryce - it looks like our slack <-> irc bots are dead for both irc channels?14:16
sgordonok so there are rhel packages but no way to use them14:16
sgordonsweet14:16
sgordonlol14:16
jodhsgordon: We found a few complications working with rhel. I'd recommend giving CentOS a go but please feel free to raise an issue on RHEL support so we can try to kickstart that work. patches welcome of course ;)14:18
gwhaleysgordon: the folks who were looking at the RH install do look like they might be out for xmas now. We'll pick this up in the new year, as we strongly desire to have a RHEL installer working.14:24
gwhaleyat that point, I expect we'll pick the work up with kata. So, pls do ping us in the new year, and let's get some joint effort to get this sorted eh?14:24
sgordonjodh, i really need to do it on rhel unfortunately as ideally i'd like to try and prove out that it a) can work with the rhel kernel and b) can work with qemu-kvm-rhev as shipped with RHV/OSP14:25
sgordonjodh, i managed to push myself onwards to a different error now anyway ;)14:25
jodhsgordon: understood. oh right - well if you do want to raise an issue, maybe we can get more eyes on the problem?14:27
sameosgordon: Which error do you get?14:30
sgordonim now at level=error msg="qemu-kvm: -append root=/dev/pmem0p1: Could not open 'rootflags=dax,data=ordered,errors=remount-ro'14:31
sgordonwhich i suspect is in fact an issue with what i am trying to do with qemu14:31
sgordon(which is what i wanted to hit)14:31
sameosgordon: No nvdimm support for qemu?14:34
* gwhaley tracked down what version of qemu that was introduced in a while back - maybe for this exact reason14:34
sgordonsameo, probably14:35
sgordonsameo, i have a sneaking suspicion this will already be tracked separately but checking rhbz14:35
sameosgordon: That's a kernel param though...Do you know where the RHEL qemu config is ?14:36
jodhIt would be useful to see the output of "cc-runtime cc-env" possibly.14:38
sgordonsameo, yeah but i think there are a heap of NVDIMM related not in 7.414:38
sgordon*related fixes14:38

sgordonjodh, ^ be warned it's suitably all over the place at this point tho14:43
sameolooks sane to me.14:45
jodhsgordon: thanks.14:45
jodhsameo: agreed.14:45
jodhsgordon: you might want to turn on full debug - https://github.com/clearcontainers/runtime#debugging14:46
