| kata-irc-bot | <fidencio> @afrosi hey/ping. out of curiosity, the recommended sharedfs to be used with kata on s390x is 9p, is it? | 14:36 |
|---|---|---|
| kata-irc-bot | <afrosi> yes, we don't have virtiofs support on Z | 14:37 |
| kata-irc-bot | <fidencio> cool, thanks! | 14:37 |
| kata-irc-bot | <afrosi> yw | 14:37 |
| kata-irc-bot | <afrosi> I think we will meet on Monday :slightly_smiling_face: | 14:37 |

| kata-irc-bot | <eric.ernst> @afrosi - is there a technical blocker for this, or just enabling for this? In Kata, or the VMM, or? | 14:54 |
| kata-irc-bot | <fidencio> I'd guess in the hypervisor code, but either Alice or David could ellaborate more on that | 15:12 |
| kata-irc-bot | <fidencio> @eric.ernst takung advantage you're around, how do you estimate the right values to be used with pod overhead? | 15:13 |
| kata-irc-bot | <eric.ernst> “it depends” | 15:13 |
| kata-irc-bot | <eric.ernst> I’ve been looking at it as the overhead of just running the pod, not necessarily doing a particular workload. | 15:14 |
| kata-irc-bot | <eric.ernst> If you are running a large amount of file I/O, for example, your virtio back ends will be doing a decent amount of work, CPU wise. You can give a ‘swag’ for this. | 15:15 |
| kata-irc-bot | <eric.ernst> I’ve been mostly concerned around stability, which I see as memory. | 15:15 |
| kata-irc-bot | <eric.ernst> So, just run the VM. Check the usage at pod cgroup versus sum of containers; that’s the base value I’ve been using. | 15:16 |
| kata-irc-bot | <eric.ernst> As usage deviates, if your system is using horizontal or vertical autoscaling, it’ll take care of the cpu portion. | 15:16 |
| kata-irc-bot | <eric.ernst> beyond the initial swag | 15:17 |
| kata-irc-bot | <fidencio> I see. Yeah, that's a really good start! | 15:17 |
| kata-irc-bot | <fidencio> Thanks for the pointers! | 15:18 |
| kata-irc-bot | <eric.ernst> There are some details here you can checkout: https://kubernetes.io/docs/concepts/configuration/pod-overhead/ | 15:55 |
