まとめじゃなくて走り書きです．<\/p>\n

既存のマシンを仮想マシン化するために，これまでやったことや，今やっていること<\/p>\n

    \n
  1. ホストマシンで，qcow2のsparseイメージをnbdでマウントして既存のディスクの内容をコピー<\/li>\n
  2. ゲストマシンで，virtio_scsiで外付けディスクをマウントする<\/li>\n
  3. rawディスクイメージをloopでマウントして、既存ディスクをコピー<\/li>\n<\/ol>\n

    1. は，時間はかかるけれども，それほどベラボーではない．しかし，マシンが不安定になることがある．<\/p>\n

    2.は，うまくいく場合もあるが，ホストで認識できるパーティションが，ゲストでは認識できない場合がある1<\/a><\/sup>virtio_scsiでなく，IDEをエミュレートしたほうが無難なようです．<\/span>．また，仮想マシンを止めて，virt-managerによって，外付けディスクを削除しないと，ホストが不安定になることがある．<\/p>\n

    3.は，コピーにものすごく<\/del>宇宙的な時間がかかる．安定性は不明．<\/p>\n","protected":false},"excerpt":{"rendered":"
