クラブのサーバーのディスクが飛び，修復はしない方針にして，会員サービスの受け皿をどうするか相談したり，考えたりしました．<\/p>\n

無料でそこそこのレベルのサービスが受けられる，会員ホームページやMLについては，Googleのサービスを使用することになりました．クラウドでもあり，アウトソーシングでもありますね．<\/p>\n

では，会員限定の情報やファイルの蓄積をどうするか．これについては，ながねん，便利に利用してきたWikiをどうしても立ち上げたいです．そのためには，自前のサーバーを立ち上げるか，安いレンタルサーバーを利用するかのどちらかにするかということになります．<\/p>\n

前のサーバーを置いていた施設の責任者から，そこで運用しているサーバーでKVM<\/a>を走らせているが，CPUロードやディスク容量がそれほど大きくなければ，クラブのサーバーもひとつの仮想マシンとして動かしてもいい，という話があったので，うまくいくかどうか解りませんが，とりあえずそっちの方向で行ってみることにしました．<\/p>\n

私の方で，ディスクイメージを準備して，大家さんに送り，走らせてもらう，という段取りです．<\/p>\n

KVMはこれまでやったことがなくて，あちこちで情報を集めて，必要と思われるソフトは準備できました．<\/p>\n

そしてKernelモジュールも用意したんですが，<\/p>\n

modprobe kvm-amd<\/pre>\n
とやっても，エラーが出てしまいます．<\/p>\n
結論から言えば，BIOSのVirtualizationをEnableにしなければいけないのです．BIOSにVirtualizationなんてスイッチがあったことを知りませんでした．まあ，見てはいたんでしょうが，これが自分にとって必要になるとは思わず，目に入らなかったんでしょうね．<\/p>\n
これで，めでたく，<\/p>\n

となりました．アウトソーシング，クラウドに加えて仮想化です．実現すれば，他の無線クラブにはない，ICTの先端技術がすべて導入されます^^;<\/p>\n
いよいよ，ディスクイメージ作ってSlackwareをインストールしてみます．<\/p>\n","protected":false},"excerpt":{"rendered":"
