 Tobias Pankrath | I just tried to build an azure images on an azure vm, but a 'x86_64-linux' with features {kvm} is required to build '/nix/store/8pb7ph0p7j1mhwsiz9mfmp92ps6nvx24-azure-image.drv', but I am a 'x86_64-linux' with features {benchmark, big-parallel, nixos-test, uid-range}. Is there a way to circumvent this? | 12:10:43 |

| Tobias Pankrath | If anyone knows how to build images on azure, please let me know. I only found some info about instance types that support kvm (DC.*), but they don't seem to be available anymore. | 12:35:33 |
 @j4:matrix.org | Well, I'm not familiar with azure VMs supporting kvm virtualization. If your does however, you also need to configure your nix machine to accept build by adding this to settings :
nix.settings.system-features = ["kvm"];
With a quick googling (I don't have access to an azure account), seems like Ev3 / Dv3 support it. You need to look for "nested virtualization" (see https://stackoverflow.com/questions/49099428/is-it-possible-to-run-kvm-on-azure https://learn.microsoft.com/en-us/virtualization/hyper-v-on-windows/user-guide/nested-virtualization

Thanks. The output from kvm-ok was from a Dv3, so it seems kvm does not work even on machines that support nested virt. | 15:23:02 |
| @j4:matrix.org | Mmmmm, maybe it's because it's an azure thing and they only support hyperv ? :/ Not my area of expertise unfortunately Tobias Pankrath | 15:24:18 |
| Tobias Pankrath | I'll try that again tomorrow. At least according to SO it should be possible. | 15:27:48 |
| @j4:matrix.org | Please post the solution, I'm also curious about the solution :) | 15:28:23 |

 ris_ | today's discovery - you need to add cni-podman0 to networking.firewall.trustedInterfaces if you want to be able to use host.containers.internal from a podman container | 17:53:26 |
