 colemickens | on the host? | 07:22:35 |
| colemickens | hm | 07:22:38 |
 Mic92 (Old) | The host running the vm | 07:22:46 |
| colemickens | I am pretty sure I'm on cgroupsv2 yes, I hadn't quite noticed that | 07:22:57 |
| colemickens | its been a couple weeks though... | 07:23:18 |
| Mic92 (Old) | You will see it breaks container that run for longer. | 07:23:20 |
| Mic92 (Old) | The hello-world container works | 07:23:33 |
| Mic92 (Old) | but not a busybox one that is interactive | 07:23:40 |
| Mic92 (Old) | At least in the released version of kata-containers | 07:23:52 |
| Mic92 (Old) | Not sure about master | 07:23:56 |
| Mic92 (Old) | If you enable k3s or kubernetes service you might also get cgroupv1 | 07:24:15 |
| colemickens | ok, thanks for the heads up, I'll keep an eye out, I hadn't really considered that the host config would matter too much. | 07:24:23 |
| colemickens | I'm sorta hoping to try Nomad, but we'll see... | 07:24:48 |
| Mic92 (Old) | That took me way to long to figure out. | 07:24:51 |
| Mic92 (Old) | Nomad will have the same issue if it uses containerd I think | 07:25:05 |
| * colemickens nods | 07:25:25 |
| Mic92 (Old) | I am sure they will sort this out this year, but right now it is a known issue. | 07:25:39 |
| Mic92 (Old) | colemickens: a different issue is that qemu does not like read-only mounts. It is ok with not beeing able to right the image so. | 07:27:28 |
| Mic92 (Old) | That's why I copy initrds + rootfs to a location outside the nix store. | 07:27:46 |
| colemickens | I think I saw that preexecstat when skimming... but that's odd, again I'm surprised I hadn't noticed that when I was testing? | 07:28:52 |
| colemickens | * I think I saw that preexecstart when skimming... but that's odd, again I'm surprised I hadn't noticed that when I was testing? I definitely had the guest/agent booting. | 07:29:09 |
| colemickens | anyway, more good tips. | 07:29:17 |
| Mic92 (Old) | The error message comes from qemu itself. I use virtio-fs | 07:29:56 |
| Mic92 (Old) | I have not debugged this to the hypervisor itself. I only had a weekend to get it working. | 07:30:19 |
| colemickens | ok | 07:30:59 |
| colemickens | thanks for the input; one last one and then I have to run - I saw you forked vhive, any quick thoughts to share on it coming from the kata perspective? or just something you're keeping an eye on | 07:31:35 |

| Mic92 (Old) | It is based on a research project. It certainly shows what needs to be optimized to make lambda functions more scalable. But there is no big coorp like Intel working behind it. Just 4 PhD students working on their next publications. We use it in our research project to make a usecase for vmsh. | 07:33:45 |
| Mic92 (Old) | Also quality and documentation is certainly above what you would see from a average research project. | 07:34:23 |
| Mic92 (Old) | They got CI and end-to-end documentation. | 07:34:35 |
