ある日突然，仮想マシンがへそを曲げました．ホストのdnsmasqからゲストはIPアドレスを取得できず，IPv4LL (Local Link address)を自分勝手に設定するものですから，ホストとも当然外界ともつながりません．<\/p>\n

ゲストのネットワーク設定を固定IPアドレスにすると，IPアドレスは設定されますが，ホストとつながらない状況は変わりません．つまり，ネットワークの機能そのものに問題があります．<\/p>\n

KVM関係のパッケージのupdateをしましたが，事態は改善しません．<\/p>\n

結論的には，表記にあるように，QEMUをv2.7.91 (v2.8.0-rc1)にするとNGと判明しました．gitのbranchを当然ながらのmasterにしておくと，はまります^^;<\/p>\n

もちろん，今まで動いていたのに何にもしないのにある日突然動かなくなったわけではなく，いろいろアップデートの作業をしていて，気がついたら仮想マシンのネットが機能しなくなっていたと言うことです^^;<\/p>\n

そこで，QEMUをStableの2.6（v2.6.2）にして使用しようかと思いましたが，qemuだけstable-2.6にしても，あまりに古くてvirt-mangerと整合性が悪いようで，仮想マシンが動いてくれません^^;;1<\/a><\/sup>たぶん，qemu起動時のオプションの仕様が違うのだと思います．<\/span><\/p>\n

そこで，不安定版^^; だけどソースがリリースされている2.7.0にしてみました．動きました．ネットもつながります．<\/p>\n

2.8.0が正式リリースになるまでは，2.7.0を使うことにします．<\/p>\n

[追記] 2.7.92 (2.8.0-rc2)も改善なし（2016年11月30日(水)）<\/h3>\n

表題のままです．2.7.92がリリースされましたが，ネットに関する不具合は直っていません．<\/p>\n","protected":false},"excerpt":{"rendered":"
