** KVM [#v2d4e0f8]
- http://www10.atwiki.jp/noel1008/pages/44.html#id_b2b002a6
#br

*** ネットワーク [#ec3d818f]
- Guest OS(eth0) => Host OS(tap# → br0 → eth0) => external
- Host OS の tap インターフェイスは Guest OS 毎に必要
#br

*** 起動 [#f1023067]
**** 起動例 [#mb397d99]
 # /usr/libexec/qemu-kvm -hda /data/centos-base-1.img -m 1024 -k ja -vnc none -net nic,macaddr=52:54:00:12:34:00 -net tap,ifname=tap0,script=/etc/qemu-ifup
- macaddr は Guest OS のMACアドレスになる．設定し直すと /etc/udev/rules.d/70-persistent-net.rules で eth の名前が変わるので，合わせる必要がある．また /etc/sysconfig/network-scripts/ifcfg-eth# の HWADDR は削除した方が面倒くさくない．

- qemu-kvm オプション： http://opensuse-man-ja.berlios.de/opensuse-html/cha.qemu.running.html#cha.qemu.running.gen_opts
#br

**** tap インターフェイスの起動と停止 [#e551c379]
