うまく行かなかった，Debianの実マシンの仮想化<\/a>はその後成功しました．<\/p>\n\n\n\n

まっさらなqcow2の仮想ディスクイメージに実マシンのディスクの内容をコピーするという正攻法がうまく行かなかったので，Plan Bとして，仮想マシンとして動いているDebian1<\/a><\/sup>これも元をたどれば実マシンのDebian．ただし，いつ頃コピーしたかは不明．<\/span>の仮想ディスクイメージを複製し，<\/p>\n\n\n\n

を実行しました．<\/p>\n\n\n\n
--sparse<\/code>オプションは，いくつか仮想ディスクイメージがあるから指定しています．また，ないとは思いますが，ディスクがオーバーフローしないように，--inplace<\/code>も指定しています2<\/a><\/sup>ふっるーい情報だと，–sparseと–inplaceは同時に指定できないとありますが，もう何年も前から指定できる<\/a>ようになっています．<\/span>．<\/p>\n\n\n\n
このコピーの後，コピー先の\/etc\/fstabの内容を，実情に合うようにします．とはいえ，ルートだけで，UUIDなり，\/dev\/sda3なり，\/dev\/vda3と指定します3<\/a><\/sup>UUIDの場合はもうひと手間必要ですが省略します😓<\/span>．<\/p>\n\n\n\n
そして，VMmanagerで，コピーしてできたqcow2を含んだ仮想マシンをでっちあげます．<\/p>\n\n\n\n
さて，これでもまだコピーしてできた仮想ディスクイメージからブートはできませんので，DebianのインストールDVDイメージから新しく作った仮想マシン起動して，Rescueモードでなんやかんやしたらgrubで無事起動するようになりました．<\/p>\n\n\n\n
結局どこが悪かったかわからないまま4<\/a><\/sup>新規に作ったqcow2のパーティショニングかフォーマットあたりでしょうが．<\/span>ですが，動けばいいんです．<\/p>\n\n\n\n
ちなみに，この方法では一つだけ問題があります．それは，同じUUIDを持つパーティションがこの世に2つ存在することです5<\/a><\/sup>今後同じ方法で複製をすれば，さらに増える😓<\/span>．2つのディスクイメージを同じ仮想マシンに同時に装着して，UUIDを指定してパーティションをマウントしなければ問題になりませんが．<\/p>\n","protected":false},"excerpt":{"rendered":"
