<div dir="ltr"><p class="MsoNormal"><br></p><p class="MsoNormal">豊田工業高等専門学校情報科学専攻<span lang="EN-US">1</span>年の高直我と申します。<span lang="EN-US"><span></span></span></p>
<p class="MsoNormal">現在、<span lang="EN-US">BitVisor</span>を用いたシステムの開発を行っております。<span lang="EN-US"><span></span></span></p>
<p class="MsoNormal"><span lang="EN-US"> </span></p>
<p class="MsoNormal">お聞きしたいことが<span lang="EN-US">2</span>点ございます。<span lang="EN-US"><span></span></span></p>
<p class="MsoNormal"><span lang="EN-US"> </span></p>
<p class="MsoNormal"><span lang="EN-US">1</span>つは<span lang="EN-US">MacOS(Sierra
10.12.6) </span>上で<span lang="EN-US">BitVisor</span>を動作させたいと考えております。<span lang="EN-US">BitVisor Advent Calendar 2015</span>の<span lang="EN-US">4</span>日目に掲載されている<span lang="EN-US">Mac</span>で<span lang="EN-US">BitVisor<span></span></span></p>
<p class="MsoNormal"><span lang="EN-US">(<a href="https://qiita.com/hdk_2/items/6c73aac9df758dc896c1">https://qiita.com/hdk_2/items/6c73aac9df758dc896c1</a>)</span>というページを参考にして、<span lang="EN-US">EFIShell</span>から<span lang="EN-US">USB</span>ブートによって<span lang="EN-US">BitVisor</span>を起動し、<span lang="EN-US">MacOS</span>を起動することはできました。ですが起動後<span lang="EN-US">BitVisor</span>、ゲスト<span lang="EN-US">OS</span>共にネットワークに繋がりません。上記した参照ページに記載されている、ネットワークドライバのアンロードは行っています。<span lang="EN-US"><span></span></span></p>
<p class="MsoNormal"><span lang="EN-US">NIC</span>は<span lang="EN-US">Broadcom</span>社のものを使っているため、<span lang="EN-US">config.vmm.driver.pci="class_code=020000, id=14e4:1686,
number=0, driver=bnx, net=ippass, virtio=1"</span>と指定しています。また<span lang="EN-US">bitvisor</span>の<span lang="EN-US">ip</span>を<span lang="EN-US">192.168.1.235</span>と静的に与えており、<span lang="EN-US">BitVisor</span>の<span lang="EN-US">IP</span>が正常に割り当てられていることを<span lang="EN-US">dbgsh</span>から確認しました。また、<span lang="EN-US">MacOS</span>上で<span lang="EN-US">ethernet</span>カードが<span lang="EN-US">virtio</span>デバイスとして認識されていることも確認しています。ゲスト<span lang="EN-US">OS</span>に組み込んだ<span lang="EN-US">virtio-net</span>モジュールは<span lang="EN-US">GitHub</span>上で公開されていた<span lang="EN-US">virtio-net-osx(<a href="https://github.com/pmj/virtio-net-osx">https://github.com/pmj/virtio-net-osx</a>)</span>を用いています。<span lang="EN-US"><span></span></span></p>
<p class="MsoNormal"><span lang="EN-US"> </span></p>
<p class="MsoNormal"><span lang="EN-US">2</span>つ目として、私は研究で<span lang="EN-US">BitVisor1</span>上の<span lang="EN-US">ahci</span>ドライバにストレージ<span lang="EN-US">IO</span>の監視システムを組み込む、ということを行っています。そしてそのシステムを<span lang="EN-US">MacOS(</span>バージョンは前述のとおりです<span lang="EN-US">)</span>で動作させたいと考えております。そこで<span lang="EN-US">defconfig</span>に<span lang="EN-US">ahci</span>を捕捉するように記述をして、<span lang="EN-US">EFIShell</span>から<span lang="EN-US">USB</span>ブートの形で<span lang="EN-US">BitVisor</span>を起動したあとにゲスト<span lang="EN-US">OS</span>を起動<span lang="EN-US">(/System/Libray/CoreServices/boot.efi</span>を実行<span lang="EN-US">)</span>しようとすると、<span lang="EN-US">/System</span>以下のディレクトリへアクセスできなくなってしまいます。<span lang="EN-US">ahci</span>をパススルーさせると<span lang="EN-US">/System</span>以下のディレクトリへ<span lang="EN-US">cd</span>でき、<span lang="EN-US">boot.efi</span>を実行することで<span lang="EN-US">OS</span>の起動ができます。<span lang="EN-US">MacOS</span>の環境下では<span lang="EN-US">ahci</span>を捕捉できないのでしょうか。<span lang="EN-US"><span></span></span></p>
