VisualBox之所以在Linux上比传统的VMware快得多,关键一点就是它和Linux内核的结合比较紧密,这也是开源的优点. 不过Linux内核更新很频繁,每次更新内核后启动VirtualBox都会提示: VirtualBox kernel driver not installed. The vboxdrv kernel module was either not loaded or /dev/vboxdrv was not created for some reason. Re-setu…

kernel module version check bypass . 举例说明 . 内核是怎么实现的 . 怎样去突破 . 总结 . 举例说明 Linux内核版本很多,升级很快,2个小内核版本中内核函数的定义可能都不一样,为了确保不一致的驱动程序导致kernel oops, 开发者加入了模块验证机制.它在加载内核模块的时候对模块进行校验, 如果模块与主机的一些环境不一致,就会加载不成功. 看下面一个例子,它简单的输出当期系统中的模块列表: ---------------------------…
