某所で動いている実用サーバーのバックアップから仮想ディスクを起こして起動させる<\/a>テストの続きです．<\/p>\n\n\n\n

一昨日うまく行かなかった<\/a>理由はDebianのインストール用DVDイメージのRescueモードから，作った仮想ディスクにchrootしていたからです．この方法だとchrootの前のおまじないが足りないということは，随分前に経験済み<\/a>だったのですが，同じところで一日はまり込んでいたわけです．<\/p>\n\n\n\n

この日の作業では，まず上記Debianのインストールディスクでchrootしてうまく行っていなかった，DOSパーティションの仮想ディスクに，Gentoo方式で正しくchrootして<\/a>，grub-install, grub-mkconfigを実行して，ちゃんとブートするようになりました1<\/a><\/sup>使用したインストール用DVDイメージはSlackware64 15.0．<\/span>．<\/p>\n\n\n\n

次に，まっさらな仮想ディスクを仕立て，GPTパーティションとしてBIOS boot領域とルートの2パーティションにして，バックアップからコピーをして，同様にchrootしてgrub-install, grub-mkconfigをし，こちらもブートするようになりました2<\/a><\/sup>同じくSlackware64 15.0．<\/span>．<\/p>\n\n\n\n

どちらの仮想イメージについても，Bookwormに無事upgradeできました．<\/p>\n","protected":false},"excerpt":{"rendered":"
