今まで知らなかった，KVMについて，実際にインストールして，無線クラブの会員向けサーバーとなる予定の仮想マシンのディスクイメージを作成しました．<\/p>\n
そもそも，Slackwareは，KVMをサポートしていませんので，必要なソフトをいろいろかき集めてインストールして，最終的にはvirt-managerで，仮想マシンの作成，稼働，停止までできるようになりました．<\/p>\n
無線クラブのサーバーの作成の他には，自宅サーバーのクローンを作成して，懸案だった，httpd 2.2→2.4の試行に利用して，その手順によって，実サーバーのhttpdを短いダウンタイムでupgradeすることができました．<\/p>\n
というわけで，興味もポテンシャルも上がったのですが，では，次に何をするかとなると，思いつきません．<\/p>\n
攻撃を受けやすい外部向けサービスを仮想マシンに移転するというのは，実利的かもしれません．実サーバーから仮想マシンへは入れるけど，仮想マシンから実マシンには入れないようにしておけば，仮に仮想マシンがクラックされても，実マシンへ侵入されにくくなります．<\/p>\n
デメリットとしては，仮想マシンとはいえ，ちゃんと管理すべきで，お守りをするマシンが１台増えるということになります．<\/p>\n
それから，GUIも動きますが，どうしてもモニターの表示領域をフルには使えませんから，GUIがメインの用途には今ひとつです．<\/p>\n
ということで，いまひとつおもしろくないです^^; どうしたものか．<\/p>\n","protected":false},"excerpt":{"rendered":"
