• Cmderを使う

$ choco install cmdermini.portable

• 最大化抑制

• CentOS6 (http://wiki.centos.org/Download) からISOを落とす
• eth0 (NAT), eth1 (host-only)
• リブートしても /etc/sysconfig/network-scripts/ifcfg-eth0（ethも) がONBOOT=no になっているので、=yesに変えて　networking restart
• これで 192.168.56.101（とか)のゲストにsshできる

• yum/wgetをproxy経由で使う方法(CentOS)
• /etc/yum.conf

proxy=http://172.165.101.254:8080
