Qemu For Cisco Asa 简单解说

此文档适用于windows平台
一：所需软件
  1：qemu-0.9.0-windows. qemu的windows版本
  2：Bes解决cpu100%问题
  3:asa802-k8.gz 这个是asa的ios,关于ios的名称问题 可以解压出来,也可以用.gz格式的.在qemu命令中要定义出来
  4:vmlinuz：是可引导的、压缩的内核
三：安装过程
1：把所需软件解压放一个目录 例如netemu此目录应该包含qemu-0.9.0-windows解压后的文件,asa802镜像 vmlnuz文件
2：创建FLASH 命令格式

E:\cisco asa>qemu-img.exe create FLASH 265M

Formating 'FLASH', fmt=raw, size=271360 kB
3：qemu -L . -hda FLASH -m 256 -kernel vmlinuz  -initrd asa802-k8.gz -append "auto ide1=noprobe console=ttyS0,9600   bigphysarea=16384" -serial telnet::1234,server,nowait
注意此命令在一行输入,可以先输入到文本中排列成一行.
4:打开bes 限制qemu的cpu 解决cpu100%问题
5：telnet 127.0.0.1 1234
