Interel net on KVM

NA 作業要求我們要架初一個 NAT + DHCP 的環境

但是 KVM 設置網路環境時會幫你自動裝好 DHCP ，這樣反倒會無法自己來

參考了 libvirt 官方 wiki 後

找到了可行的黑暗兵法 

$ sudo vim /etc/libvirt/qemu/networks/default.xml

<network>                                                                       
  <name>default</name>                                                          
  <bridge name="virbr%d" />                                                     
  <forward/>                                                                    
  <ip address="192.168.122.1" netmask="255.255.255.0">                          
    <dhcp>                                                                      
      <range start="192.168.122.2" end="192.168.122.254" />                     
    </dhcp>                                                                     
  </ip>                                                                         
</network>

把 <dhcp></dhcp> tag 裡的東西通通 dd 掉！

<network>                                                                       
  <name>default</name>                                                          
  <bridge name="virbr%d" />                                                     
  <forward/>                                                                    
  <ip address="192.168.122.1" netmask="255.255.255.0">                                                                                            
  </ip>                                                                         
</network>

It works! XD
