自分の周りは、いうことなすこと結構無茶苦茶な人が多い。家の隣で工事しているが、まぁ、家をぶっ壊すし、メールは、いうことがバランバラン。これで上場企業のお偉いさんなのか？といいたくなるくらい無茶苦茶。もしかして、上場企業のお偉いさんって、このレベルでなれちゃうのかなぁ。だとすると、この日本の物価高や円安もわからないことはない。海外へ行って、ラーメンが3000円だっ！って驚く人が多いけど、グローバルでみたら、30万円の給料の人が今は10万円になった。1000円のラーメンが高いといっているのと同じではないかと。。。バイトだと時給1000円超えているが、3,400円になったら、やはりラーメン1000円は高いとなるだろう。その上場企業のお偉いさんを見る限り、その企業は、能力に応じた給料で下げない代わりに人の能力を落とすことで帳尻を合わせているのではないかと。これじゃぁ万博の工事も進まないのは納得。
閑話休題
KVMの環境って、実はいろいろなところで実は手に入る。IntelベースのSynologyやQNAPでもKVMの仮想マシンを立ち上げることができる。（CPUが遅いとほんと遅いけど。）
手元で動かせるKVM仮想マシンを片っ端から調査してみた。結構バラバラ。どれがいいのか悪いのかは置いておいて。
