ホスティングサービスなどでは仮想マシンは実用的な技術ですが，個人では作っては崩しを繰り返す箱庭遊びみたいなもんです．それでも実マシンから仮想マシンへ，あるいはその反対方向へ，またはKVM\/QEMUからVMWareといった具合に違うシステムのホストの間で，と移転させるのには若干のノウハウが必要です．<\/p>\n\n\n\n

時々思い出しては遊びますが，じきに飽きます．<\/p>\n\n\n\n

しかし今回実マシンを破壊してしまって仮想マシンから “復元” <\/a>することになりました1<\/a><\/sup>最終的には実マシンのbackupから本当の復元<\/a>ができました．<\/span>．その際1年間のブランク<\/a>のため，無駄な試行錯誤が必要でした．<\/p>\n\n\n\n

これからは時々は箱庭遊びをして勘所を忘れないようにしたいと思います．<\/p>\n\n\n\n

定期的に実マシンを仮想マシンに移転するのがバックアップの意義があって良さそうですが，新しく移転したら “かわいがってきた” 古い仮想マシンを未練なく消せるのか2<\/a><\/sup>仮想マシンの仮想ディスクは数十GBの実ディスク容量を専有しますから，無制限には残せません．<\/span>，という問題もあってちょっと考えなければなりません．<\/p>\n","protected":false},"excerpt":{"rendered":"
