 @ulrikstrid:matrix.org | What is the correct way of building a nixosConfiguration? | 17:44:38 |
 kenran_ | In reply to @ulrikstrid:matrix.orgWhat do you mean exactly? A NixOS configuration with a hydra service? Your question sounds like it's about the flake output type. | 19:18:01 |
| kenran_ | In reply to @lewo:matrix.orgIt's in system-features, but that's probably not what you mean!? The machine is a VM in the cloud; I'll check tomorrow, but given that it takes 5 minutes to run this test I don't think it is :) | 19:19:24 |
| @ulrikstrid:matrix.org | In reply to @kenran_:matrix.orgI manage my computers with flakes and want to have my hydra build the configurations and ideally I would deploy from that | 19:33:14 |
 lewo | kenran_: having kvm in system-features is not enough to ensure Nix have enough permissions on /dev/kvm (if nested KVM is provided by your cloud provider) | 19:36:15 |
| kenran_ | In reply to @ulrikstrid:matrix.orgOh, that sounds very nice! I'm interested in knowing more now, too! Is the building part just adding a hydraJobs.my-host.${system} = self.nixosConfigurations.my-host? | 19:36:28 |
 das_j | In reply to @lewo:matrix.orgAdding kvm to the system features is already wrong. Nix autodetects kvm and adds the feature | 19:36:46 |
| lewo | kenran_: and if KVM is not available, it can be pretty hard to get NixOS test working. | 19:37:08 |
| das_j | In reply to @janne.hess:helsinki-systems.dehttps://github.com/NixOS/nix/blob/master/src/libstore/globals.cc#L128-L129 | 19:37:33 |
| kenran_ | In reply to @lewo:matrix.orgI probably know way too little about kvm, but I was under the impression (someone in the nixos channel told me) that they should be running even without "actual" kvm support. Surely you're right of course. I'm just trying to understand: does that explain why some versions of the tests work, but others don't? | 19:38:35 |
 ajs124 | vm tests should run, just very very veeeeeryyyy slow | 19:39:07 |
| lewo | KVM provide hardware acceleration of virtualization functions. So, if you don't have it, it can be really slow (order of magnitude)... | 19:39:50 |

| kenran_ | In reply to @andreas.schraegle:helsinki-systems.deYeah, that's what I saw happening :D veeeeerry slow indeed! The same 5-minute test runs in like 15 seconds on my machine. | 19:40:09 |
| lewo | So, fisrt, you need to be sure KVM is available. | 19:41:52 |
| kenran_ | Ok, so thanks! I know what I can try first: this hydra instance is something I set up to test how things work, and if you can use it for some projects at work, and I'm loving it so far (except for those NixOS tests). I don't think the provider enables kvm for that kind of virtual machine, though, so I'll have to see what other options there are to set it up on. | 19:41:56 |

| kenran_ | And when that's done and the tests run: fine! If not, I can come here and try to pester you with questions again :) | 19:42:54 |
| @ulrikstrid:matrix.org | In reply to @kenran_:matrix.org servern = self.nixosConfigurations.servern.config.system.build.toplevel; This seems to build it, but it looks very hacky and I'm not sure I can use it to deploy anything 🤪 | 20:13:12 |
| @ulrikstrid:matrix.org | From here https://github.com/ulrikstrid/nix-config/blob/main/flake.nix#L119-L122 | 20:13:30 |
| kenran_ | In reply to @ulrikstrid:matrix.orgOh yeah, this looks awful :D but have you tried doing anything with it? Say, nixos-rebuild switch --flake .#hydraJobs.servern.x86_64-linux, for science? | 20:15:07 |
| @ulrikstrid:matrix.org | Not at my computer but can try out tomorrow morning | 20:21:34 |
| @ulrikstrid:matrix.org | My hydra builds or btw, but the output is < 1mb | 20:22:17 |
| @ulrikstrid:matrix.org | The closure is in the GB range so I'm pretty sure it's building | 20:22:43 |

 Dandellion | I'm trying to build a flake in hydra, but I'm having a lot of issues When I evaluate I get Has anyone seen aything like that before? | 21:16:03 |
