尝试访问ubuntu 14.04中的KVM代码时遇到问题

Question

我的虚拟化项目要求我对KVM的vmx.c文件进行更改。我已经在Ubuntu 14.04操作系统中安装了KVM，并且还完成了启动实例的操作。但是，当我在系统中查找vmx.c时，我确实找不到它，尽管我在以下目录/usr/src/linux-headers-3.19.0-30/arch/x86/include/asm中找到了vmx.h文件，如果有人可以指导我我该怎么办。谢谢您！

To be able to modify KVM without recompiling all the kernel, you can use Jan Kiszka's repo for building an external KVM module as following:

git clone git://git.kiszka.org/kvm-kmod.git
cd kvm-kmod
git submodule update --init
./configure
make sync
make

You can find after that the files you need in kvm-kmod/x86/ and you can modify them as you need. To install your modified version you can use run from the kvm-mod directory:

    make
    sudo su
    rmmod kvm-intel
    rmmod kvm
    insmod kvm
    insmod kvm-intel

You can put these commands in a script file to avoid typing them each time ;)
