| brtknr | @channel would someone be able to point me to a resource to enable virtio-fs for kata? | 09:45 |
|---|---|---|
| brtknr | in a kubernetes context | 09:45 |
| brtknr | just saw these results and i feel quite optimistic: https://lwn.net/Articles/774495/ | 09:48 |
| davidgiluk | brtknr: https://virtio-fs.gitlab.io/howto-kata.html is our notes for it, although that's not been updated since earlier in the week when kata merged it | 09:48 |
| brtknr | davidgiluk: since kata merged what sorry? | 09:49 |
| kata-irc-bot2 | <xu> virtio-fs is going to be included in kata 1.7 as a experimental feature | 09:49 |
| brtknr | @xu: ah so there is support for it currently? | 09:50 |
| davidgiluk | brtknr: If you're on kata less than the bleeding edge, then no, follow the instructions in the link I pasted, that should get you kata 1.6.1 | 09:50 |
| kata-irc-bot2 | <xu> in one or two weeks, I think | 09:51 |
| brtknr | davidgiluk: thanks davidgiluk :) | 10:20 |

| kata-irc-bot2 | <graham.whaley> @davidgiluk - last night I said I'd find you that ref to the other new 'vm image in docker' project we saw. It is called footloose, and kata has an Issue open to detail how we might integrate: https://github.com/kata-containers/runtime/issues/1531 | 10:39 |
| *** mugsie has joined #kata-dev | 10:39 | |
| davidgiluk | gwhaley: So is that more about the contents of the container? | 10:41 |
| davidgiluk | gwhaley: it mostly sounds like making containers that look more like a full guest | 10:43 |
| gwhaley | it does, doesn't it :-) I then wonder if you can run Kata in Kata with them? (KinK) :-) | 10:43 |
| davidgiluk | gwhaley: Well, if kata starts it's VM with nesting enabled.... | 10:45 |
| davidgiluk | [which is probably a bad idea] | 10:45 |
| gwhaley | morning yankcrime - you recovered from drinking all the left over beer and eating all the pasties last night? :-) | 10:50 |
| gwhaley | fmi, which meetup is it you are looking at for London - is that k8s or CN or ? | 10:50 |
| davidgiluk | gwhaley: My guess on that percpu_usage thing is that kata is starting qemu with max_cpus=24 and something (the runtime?) is displaying the per-cpu information for max cpus rather than for the ones that are actually present | 10:52 |
| gwhaley | davidgiluk: ok, yeah, afaik we do start with a large (==host maybe) maxcup. any chance you can put that info on the github Issue? and I'll /cc @devimc here to sync data up ^^ | 10:54 |

| brtknr | gwhaley: sounds like the manchester meetup | 12:11 |
| brtknr | gmmaha: was good | 12:11 |
| *** gwhaley has joined #kata-dev | 12:24 | |
| gwhaley | brtknr: yeah, was a good meetup. pretty busy. hosts were very generous with the beer and food :-) We got a bit pushed for time, it was so active - I think we all could have talked for a couple more hours easily! | 12:26 |
| yankcrime | gwhaley: hahah there was a lot left - we've stashed it at danny's flat for now so we have a cache for the next one | 12:32 |
| yankcrime | thanks again for coming, it was a good night | 12:33 |
| yankcrime | the july one in london will be an openstack / open infra meetup | 12:33 |
| yankcrime | but we've also got another cloud native / kubernetes manchester meetup planned around the same time | 12:34 |
| yankcrime | the london openstack meetup is in desperate need of a reboot really | 12:34 |
| yankcrime | not had an event for 18+ months now (not including openinfra days) | 12:34 |
| *** devimc has joined #kata-dev | 12:42 | |
| gwhaley | yankcrime: you stuffed a load of beer in Dannys flat, and hope it will still be there for the next event. heh heh heh... yeah, sure ;-) I can see you around there on Monday for a GoT/beer fest then... | 12:43 |
| gwhaley | np - I just needed some idea of which meetup it is to get my travel request submitted internally early - I'll go do it now | 12:44 |

| brtknr | gwhaley: Our blog article related to comparing disk IO performance of Kata against baremetal and runC is live: https://www.stackhpc.com/kata-io-1.html, looking forward to the next stage of the test with virtio-fs, I'm optimistic :D | 15:30 |
| kata-irc-bot2 | <eric.ernst> nice article - the pictures are much better there than in slack :slightly_smiling_face: | 15:44 |
| kata-irc-bot2 | Action: eric.ernst wonders if something like network attached storage would be more optimal | 15:45 |
| gwhaley | thanks for the link brtknr: I'll go read :-) Yeah, virtio-fs should show visible improvements. I too have never gotten around to trying the network attached (gluster, ceph etc.) methods either... yet | 15:50 |
| *** sameo has quit IRC | 15:51 | |
| gwhaley | brtknr: typo early on s/Inter/Intel/ :-) | 15:53 |
| brtknr | gwhaley: Do a page refresh :) | 15:53 |
| gwhaley | brtknr: not working for me - could be my browser. phrase is `Kata has roots in Inter Clear Containers`, just for ref | 15:54 |
| brtknr | gwhaley: Strange, it is definitely updated on our end :S | 15:56 |
| gwhaley | np - probably cached for me at the moment somewhere between there and here ;-) | 15:56 |
| brtknr | @eric.ernst what do you mean by network attached storage being optimal? | 15:56 |
| brtknr | gwhaley: Hope we havent made too many controversial claims | 16:00 |
| brtknr | :P | 16:00 |
| kata-irc-bot2 | <graham.whaley> hey, numbers is numbers. We know 9p lacks, and virtio-fs should be significantly better. There are also then block backed mounts, and then network storage to also put in the mix. | 16:03 |
| kata-irc-bot2 | <graham.whaley> also, fio is complex and the number of storage scenarios is huge - so, it's a hard field to cover comprehensively - as long as one makes that clear :slightly_smiling_face: | 16:04 |
| yankcrime | brtknr: i'm seeing the same typo fwiw | 16:13 |
| brtknr | yankcrime: gwhaley: oops sorry i know what the problem is, will be fixed shortly | 16:16 |
| yankcrime | gwhaley: it'll be this group - https://www.meetup.com/Openstack-London/ | 16:18 |
| kata-irc-bot2 | Action: graham.whaley joins... thx | 16:20 |
| brtknr | Oky fixed :) | 16:20 |
| yankcrime | brtknr: still says inter here | 16:22 |
| yankcrime | deffo not cached, just tried in a diff browser | 16:23 |
| yankcrime | well not cached on my end anyway | 16:23 |
