その後も，KVMはいじっていまして，ほぼ実用的に使える領域に達した感じがします．<\/p>\n

最後の問題が，Xorgの起動でした．サーバーとして使うには必要ありませんが，既存のWSを，いつでも動かせるような形で保存しておくためには必要です．<\/p>\n

その既存の実マシンから移行した仮想マシン(VM)では，Xが起動してくれない，起動してもシステムがクラッシュしてしまう，解像度が1280×720より上げられない1<\/a><\/sup>この解像度については，新規作成のVMでも同じ限界がありました．<\/span>，等の問題がありました．<\/p>\n

Slackwareのxとxapを全部削除して，全部最新版をインストールし直すという手荒なupgradeを実行して，あとは，xorg.conf, xorg.conf.dの中身を見直す2<\/a><\/sup>結果的には，\/etc\/X11\/xorg.conf.d\/90-keyboard-layout.confで，keyboard layoutをjp106にoverrideするのみです．<\/span>ことで，どのVMも起動するようになりました3<\/a><\/sup>1台だけ，glibcも古すぎて，新しいxorgが起動しなかったので，gccとglibcをSlackBuildしてupgradeしました．<\/span>．<\/p>\n

起動したVMのxorgでは，最大の解像度が1280×768ですが，実際には，1280×720の中で仮想的に縦の解像度が768となるという，使いにくい状況で，実質的に1280×720が最高の解像度でした．<\/p>\n

解像度をもっと上げる方法をネット検索してみましたが，QXLを使用せよというのが一番多い情報でした．しかし，どれも2010から2011年くらいの情報です．virt-managerでは，デフォルトでQXLが選択されていて，その結果最大1280×720なので，話になりません．<\/p>\n

あとは，自分で試すしかないので，ビデオをVMVGAにしたところ，最大2368×1770までの多彩な解像度が選べるようになりました．<\/p>\n

ネット検索は万能な様な気がしますが，こういう旬な技術には，賞味期限切れ情報のほうが多くヒットしてしまって困ります^^;<\/p>\n

ホストの解像度との兼ね合いもあるので，1440×900にしてみました．\"20150114-hirez\"<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
