Slackware 14.2 (AMD64)ベースのサブWSですが，どうも最近KVMで動かしているdebianが不安定です．以前，再起動できないまで壊れてしまいました<\/a>が，そこまでひどいトラブルはないものの，よく固まります．仮想マシンなので，強制リセットすれば再起動しますが，ちょっと安心して使えない頻度で固まります．<\/p>\n\n\n\n

原因は，KVM環境のライブラリーなどをupdateしないまま，Kernalだけ最新のものにupdateしているせいだと思います．あるいは，Linuxにありがちですが，新しいKernelにバグが含まれているのかも知れません．<\/p>\n\n\n\n

たいていのソフトは，Kernelを更新しても影響はないのですが，KVM(Kernel-based Virtual Machines)は，その名の通りKernelに直結して動くので，影響が少なからずあるのでしょう．知らんけど😓<\/p>\n\n\n\n

しかし，現実問題としてSlackwareで，自分でインストールしたKVM環境全てをup to dateにするのは，もはや気力がありません😓<\/p>\n\n\n\n

そこで考えたのは，サブWSのメインOSをdebianにしてしまおうということです．debianにKVMをインストールすれば，ライブラリーなど関係のパッケージも最新に保たれるはずです．<\/p>\n\n\n\n

仮想マシンのディスクイメージは独立したパーティションに置いているので，移行もそんなにめんどうではないと思います．<\/p>\n\n\n\n

長年愛用してきたSlackwareをLinuxのメインWS（全体としてはサブWSだけど😓）のサブOSにしてしまうのは，ちょっと悲しい気もします．そして，debianの実マシンでdebianの仮想マシンを動かす意味があるのか😓 いや，そもそも，たまにしか電源を入れないサブWSで仮想マシンを動かす意義は?<\/p>\n\n\n\n

まあ，考えてみれば，動かすことができる環境を維持していることのみが意義です．<\/p>\n\n\n\n

そう考えると，時間をかけてもSlackwareのKVM環境を手作業1<\/a><\/sup>「手作業」といっても，sbopkgに頼る部分がかなりあります．<\/span>でup to dateにするべきなのかもしれません．<\/p>\n","protected":false},"excerpt":{"rendered":"
