我正在尝试使用nixos-generators在安装了 nix 包管理器的 Ubuntu 机器中构建 AMI。我有这个配置:
$ cat configuration.nix
{ pkgs, ... }:
{
imports = [ <nixpkgs/nixos/modules/virtualisation/amazon-image.nix> ];
ec2.hvm = true;
environment.systemPackages = with pkgs; [ git ];
}
然后我使用这个命令来创建一个 AMI:
$ nixos-generate -f amazon -c ./configuration.nix
these derivations will be built:
/nix/store/zc68psb6kxz9sxqr82bqs7x6c3vamnbd-nixos-amazon-image-20.09pre-git-x86_64-linux.drv
error: a 'x86_64-linux' with features {kvm} is required to build '/nix/store/zc68psb6kxz9sxqr82bqs7x6c3vamnbd-nixos-amazon-image-20.09pre-git-x86_64-linux.drv', but I am a 'x86_64-linux' with features {benchmark, big-parallel, nixos-test}
您可以看到我得到的上述错误。我确实知道我的系统能够运行 KVM 虚拟机:
$ kvm-ok
INFO: /dev/kvm exists
KVM acceleration can be used
根据阅读文档,我填充了nix.conf
这个:
$ cat ~/.config/nix/nix.conf
system-features = "kvm"
为此,我收到了这个奇怪的错误:
$ nixos-generate -f amazon -c ./configuration.nix
these derivations will be built:
/nix/store/zc68psb6kxz9sxqr82bqs7x6c3vamnbd-nixos-amazon-image-20.09pre-git-x86_64-linux.drv
error: a 'x86_64-linux' with features {kvm} is required to build '/nix/store/zc68psb6kxz9sxqr82bqs7x6c3vamnbd-nixos-amazon-image-20.09pre-git-x86_64-linux.drv', but I am a 'x86_64-linux' with features {"kvm"}
关于如何解决此问题并构建 AMI 的任何想法?
