注意:我认为这是一个悬而未决的问题:http://lists.xenproject.org/archives/html/mirageos-devel/2016-02/msg00076.html和https://github.com/mirage/mirage-bootvar-xen/issues/17
我试图获得"你好"例如,在AWS中运行的海市蜃楼骨架。我正在使用" ec2.sh"来自海市蜃楼存储库的脚本,我在运行时遇到错误。
我配置,构建,然后部署和运行这样的示例:
> cd ../mirage-skeleton/hello/
> mirage configure --xen
> gmake
> ec2.sh -k mir-console.xen
> ec2-run-instances --region us-west-1 ami-dc96e5bc
在EC2控制台的系统日志中,在引导消息之后,我收到此错误:

这些是我安装的海市蜃楼库的版本:
mirage 2.7.0 The MirageOS library operating system
mirage-bootvar-xen 0.3.1 Library for reading MirageOS unikernel boo
mirage-clock-xen 1.1 A Mirage-compatible Clock library for Xen
mirage-conduit 2.2.0 Virtual package for the MirageOS Conduit t
mirage-console 2.1.3 A Mirage-compatible Console library for Xe
mirage-dns 2.5.0 Virtual package for the MirageOS DNS trans
mirage-entropy-xen 0.3.0 MirageOS entropy device
mirage-http 2.5.1 MirageOS HTTP client and server driver
mirage-net-xen 1.5.0 Ethernet network device driver for MirageO
mirage-profile 0.6.1 Collect profiling information
mirage-types 2.6.0 Module type definitions for Mirage-compati
mirage-types-lwt 2.6.0 Lwt module type definitions for Mirage-com
mirage-vnetif 0.1.0 Virtual network interface and software swi
mirage-xen 2.3.3 MirageOS library for Xen
mirage-xen-minios 0.8.0 Xen MiniOS guest operating system library
mirage-xen-ocaml 2.3.4 MirageOS headers for the OCaml runtime
mirage-xen-posix 2.3.4 MirageOS library for posix headers
供参考,对于"你好"例如,config.ml文件是:
open Mirage
let key =
let doc = Key.Arg.info ~doc:"How to say hello." ["hello"] in
Key.(create "hello" Arg.(opt string "Hello World!" doc))
let main =
foreign
~keys:[Key.abstract key]
"Unikernel.Main" (console @-> job)
let () =
register "console" [main $ default_console]
和unikernel.ml是
open Lwt
module Main (C: V1_LWT.CONSOLE) = struct
let start c =
for_lwt i = 0 to 4 do
C.log c (Key_gen.hello ()) ;
lwt () = OS.Time.sleep 1.0 in
return ()
done
end
我在最新版本的MirageOS中读到了一些关于启动/内核参数的新功能。我需要在config.ml中更改一下来解决这个问题吗?
我应该补充一点,这个示例 在Xen中本地工作:
> sudo xl create -c console.xl
Xen Minimal OS!

Initialising console ... done.

正如我所提到的,这似乎是一个悬而未决的问题。对我有用的是遵循页面底部的建议https://github.com/mirage/mirage/issues/493,这是将opam-bootvar-xen的分支命名为https://github.com/talex5/mirage-bootvar-xen/tree/qubes。
我有一些问题只是试图克隆和检查qubes分支,所以我最终下载了zip并使用它。
