kata-irc-bot1<tuan.hoang1> Hello, has anyone recently tried to build a custom image using the guide at ```https://github.com/kata-containers/documentation/blob/master/Developer-Guide.md#set-up-a-debug-console``` ?08:51
kata-irc-bot1<tuan.hoang1> I'm following it and having this issues when running : ``` tmhoang@localhost:$ sudo docker run --runtime kata -ti busybox 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. ``` after building the image. Both Alpine and Ubuntu on x86 failed with this.08:53
kata-irc-bot1<tuan.hoang1> Collecting debug logs ....08:53
kata-irc-bot1<tuan.hoang1> ``` kata-runtime kata-env ``` : https://tpaste.us/pWxm08:56
kata-irc-bot1<tuan.hoang1> ```kata-collect-data.sh : https://tpaste.us/W1dB ```08:57
kata-irc-bot1<tuan.hoang1> Searched through kata issues on github, but no luck08:58

kata-irc-bot1<graham.whaley> @raravena80 - I think @eric.ernst has spent some time thinking about rootless kata - and it is on his really really wish list.... don't suppose you want to chase it do you? ;)09:36
kata-irc-bot1<graham.whaley> @tuan.hoang1 - I've not tried the debug console for a while - last time I tried it I fixed the wiki page so it worked :slightly_smiling_face:  @james.o.hunt, I'm guessing you maybe ran this recently? Do you remember if there are any caveats or restrictions?09:38
kata-irc-bot1<james.o.hunt> @graham.whaley - debug console works fine afaik. @tuan.hoang1 - the key error you are getting seems to be "`qemu-lite-system-x86_64: cannot set up guest memory 'pc.ram': Cannot allocate memory`". It would help if you could raise this issue on github (https://github.com/kata-containers/runtime/issues/new) as pb's tend to expire ;)09:43
kata-irc-bot1<tuan.hoang1> Thanks for the instruction, I'm digging a little bit more with that09:44
kata-irc-bot1<tuan.hoang1> @james.o.hunt: I guess when building Alpine image (with AGENT_INIT=yes I guess) how does your "debug systemd service" look like ? A  service file in rootfs/etc/init.d/kata-debug ?09:53
kata-irc-bot1<graham.whaley> @tuan.hoang1 - ah, if you are alpine initrd, then you don't have systemd I guess, so that might not work? That was the sort of restriction I was thinking about... ;)09:56
kata-irc-bot1<tuan.hoang1> okay I'd stick with ubuntu the09:56
kata-irc-bot1<james.o.hunt> @tuan.hoang1 - yes, I'd start simple and use an image rather than initrd as @graham.whaley is correct.09:57
kata-irc-bot1<tuan.hoang1> long story short, the monkey behind keyboard didn't build the accompanying kernel with the image.13:01
kata-irc-bot1<tuan.hoang1> :-)13:01
kata-irc-bot1<graham.whaley> @tuan.hoang1 :slightly_smiling_face: at least you found the problem! We call it PICNIC .... Problem In Chair, Not In Computer :slightly_smiling_face:13:11
kata-irc-bot1<tuan.hoang1> yeah PEBKAC13:12
kata-irc-bot1<tuan.hoang1> @graham.whaley while you are here, does cpu hotplug work for you on x86 ?13:12
kata-irc-bot1<tuan.hoang1> works for me though13:13
kata-irc-bot1<tuan.hoang1> ok good13:13
kata-irc-bot1<tuan.hoang1> thanks13:13
kata-irc-bot1<graham.whaley> yeah, works. we use it by default I believe when bringing up the pod/container - if it did not work none of our tests would work on the CI I suspect13:15
kata-irc-bot1<graham.whaley> in 'days of old' (not actually that long ago - <12 months), we didn't hotplug cpus - we did static VM creation. But, we moved to hotplug of cpus so we could better match pod/container resource requests into the VMs.13:16
kata-irc-bot1<graham.whaley> @julio.montes and I think @jose.carlos.venegas.m are the masters of that ;)13:16

kata-irc-bot1<vbatts> Good morning, knerds14:44
kata-irc-bot1<raravena80> I'll take a look after the fixes go into the kubelet and the kube-proxy :)14:44
gwhaley'knerds' - heh heh14:45
kata-irc-bot1<samuel.ortiz> @vbatts morning14:46
kata-irc-bot1<vbatts> http://lists.katacontainers.io/cgi-bin/mailman/listinfo/kata-dev is non-TLS...14:50
gwhaleyooh ^^ @CahnServ @openstack - is that something you know about or can look into?14:50
gwhaley@ChanServ ^^14:50
kata-irc-bot1<graham.whaley> cc @thierry for good measure..14:51
kata-irc-bot1<thierry> @verytired1 might know more about this ^14:58

kata-irc-bot1<eric.ernst> hi @vbatts16:38
kata-irc-bot1<eric.ernst> @julio.montes - I am pretty concnered about the vsock kernel bug.16:39
kata-irc-bot1<eric.ernst> I think we should look @ masking the CID to only be u32.16:39
kata-irc-bot1<eric.ernst> because I don't think the "real" kernel fix will be available for a few weeks.16:40
kata-irc-bot1<eric.ernst> WDYT?  Withtout this, anythinng with vsock=true will fail (all Firecracker, a good amount of QEMU configs of Kata)16:40
* gwhaley looks for stefanha ... does not see him... might be good for input on ^^^16:41
kata-irc-bot1<eric.ernst> From reading the launchpad issue, it won't be released until a few weeks later in Febr16:42
gwhaleystefanha is over on kata-dev - which might be a better place for this chat16:42

kata-irc-bot1<thierry> re: lists.katacontainers.io being non-TLS : one may argue that making it TLS would give you a false sense of security (since anyone can trigger the sending of your list password in plaintext email).17:07
kata-irc-bot1<thierry> so mailman servers are often non-TLS as a result.17:07
