Could not open Selected VM debug port (8700)

在Ubuntu11配置Android開發環境的時候，遇到 Could not open Selected VM debug port (8700) 錯誤，解決方法如下

sudo vi /etc/hosts

127.0.0.1 localhost 127.0.1.1 kimbook.ubuntu-domain ubuntu

# The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ~

確保第一行為：127.0.0.1 localhost 重啟機器，問題解決！
