KVMのディスクイメージをホストやその他のマシンでマウントしていじることができます．そのために，nbdというKernel moduleと，qemu-nbdというツールが必要です．<\/p>\n
どうしようもなくなった仮想マシンを修復したり，実機をクローニングして仮想マシンに仕立てるようなときに非常に便利です．しかし，どうしたことか，これらを使ってマウントした仮想マシンのディスクイメージにrsync等を使って大量にファイルの読み書きをかけると，Kernel panicに陥る可能性が非常に高いです．<\/p>\n
ということで，いつ止めても良いようなWork Stationでいじるのが無難と思います．わが家にはそういう遊軍マシンがないので^^; メインのサーバー兼ルーターがWSも兼ねていて，何度か止めて案配悪かったです．<\/p>\n
やっぱり実マシンのLinux WSは必要ですね^^;;<\/p>\n","protected":false},"excerpt":{"rendered":"
