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. ，我没有找到.虽然我在以下目录/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如何去做.谢谢您！

My virtualization project requires me to make changes in the vmx.c file of KVM.I have installed KVM in my Ubuntu 14.04 OS and am done launching an instance too.Yet,when I look up for vmx.c in the system,I do not find it.I though find a vmx.h file in the following directory /usr/src/linux-headers-3.19.0-30/arch/x86/include/asm.It would be really helpful if someone could guide me as to how do I go about it.Thank you in advance!

推荐答案

要能够在不重新编译所有内核的情况下修改KVM，可以使用Jan Kiszka的repo来构建外部KVM模块，如下所示:

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

之后，您可以在kvm-kmod/x86/中找到所需的文件，然后可以根据需要对其进行修改. 要安装修改后的版本，可以使用kvm-mod目录中的run:

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

您可以将这些命令放在脚本文件中，以避免每次都键入它们；)

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