通过shell、python脚本管理kvm 虚拟机

xiyou

一个想法：
1 python2.7
2 python的web框架 bottle
3 shell脚本管理kvm
组合在一起就可以了~  

这段时间我会用bottle 简单的实现管理kvm 主机,开源出去的~ 性能烂的话，别怪我~

    管理kvm主机完全可以在页面上完成，国外有个人用django写了这套程序，感觉还不错，只是稍复杂，bug有点多。。。。  个人觉得 自己开写一套简单的，python本身有kvm的库，大家要是觉得麻烦的话，也可以用os模块，调用virsh的命令来管理kvm主机，这完全是可行的~

https://www.webvirtmgr.net/docs/

上面是安装配置的教程

安装好需要的库之后，直接运行就好了

./manage.py runserver 10.96.60.61:8000

也可以利用这个小脚本，针对虚拟机开机，关机，重启~


用法:

• [Shell] 纯文本查看 复制代码

  查看虚拟机列表~
  # kvmctl.sh --list 
   machine1 
   machine2 
   machineN 
  开启虚拟机
   # kvmctl.sh machine2 startd 
   Starting up 'machine2' ... (daemon mode) 
  虚拟机状态
   # kvmctl.sh --show 
   MACHINE             PID     STIME   TIME 
   machine1            4856    Feb11   10:34:59 
   machine2            11155   Mar12   00:05:45 
  关闭虚拟机
   # kvmctl.sh machine1 stop 
   Shutting down 'machine1' ...

  
  

Config file example:   KVM_M=1G   KVM_HDA=$BASEDIR/$MACHINE/root.qcow2   KVM_HDB=$BASEDIR/$MACHINE/swap.qcow2   KVM_HDC=$BASEDIR/.imgs/mysql.raw   KVM_HDD=$BASEDIR/.imgs/tmp.qcow2   KVM_NET="nic,macaddr=52:54:00:00:02:52 -net tap"   KVM_PIDFILE=/var/run/192.168.0.249.pid   KVM_TCP_PORT=10000   KVM_MONITOR="tcp:127.0.0.1:${KVM_TCP_PORT},server,nowait"   KVM_EXTRA=
