| errordeveloper | I have noticed that when I set cutom kerenl, kata stops respecting memory request in my pod defaults to 2G, is this expected behaviour? | 15:42 |
|---|---|---|
| gwhaley | errordeveloper: where/how did you set the custom kernel - it might be a 'feature' indeed. | 15:46 |
| errordeveloper | gwhaley: I use `io.katacontainers.config.hypervisor.kernel` annotation on my pod | 15:50 |
| errordeveloper | when I the annotation, I get requested amount memory | 15:51 |
| errordeveloper | I suppose kata cannot tell what memory footprint of my kernel is going to be, is that it? | 15:51 |
| gwhaley | errordeveloper: I don't know - but, I thought the info would be useful so we can ask @jcvenegas and @devimc if they know... it doesn't ring any bells with me you see, and if so, we should probably document this.. | 15:54 |
| davidgiluk | errordeveloper: I didn't think it tried; have you got CONFIG_MEMORY_HOTPLUG enabled in your kernel? | 15:55 |

| errordeveloper | davidgiluk: I will check that, thanks a lot! | 16:28 |
| davidgiluk | errordeveloper: I generally try and get kernels to work using a config taken from a previous kernel that works, e.g. one of the distro kernels; then chop it down carefully | 16:29 |
| errordeveloper | that would make more sense then my original theory about kernel memory footprint calculation :) | 16:29 |
| * davidgiluk doesn't think there's anything that clever | 16:30 | |
| errordeveloper | =) | 16:30 |
| errordeveloper | ah, so here is another question... do people know anyone who actually runs systemd inside kata containers? | 16:30 |
| errordeveloper | I think I'm seeing an issue where parent systemd is killing systemd services inside the container... | 16:31 |
| davidgiluk | that should be impossible | 16:32 |
| davidgiluk | I think | 16:32 |
| errordeveloper | davidgiluk: you think systemd inside the VM shouldn't kill anything? | 16:34 |
| * davidgiluk would hope it's isolated | 16:35 | |
| errordeveloper | hm, I'd hope so too... but I'm looking at e.g. containerd's systemd unit has Delegate=yes, KillMode=process, TasksMax=infinity ...etc | 16:37 |
| errordeveloper | kata-agent.service doesn't have those properties set | 16:37 |
| errordeveloper | I'm gonna add them and see if that changes things, I don't exactly have the energy to intercept sigkills that I'm seeing here | 16:37 |
