kvm虚拟化技术实战记录（3）——编译安装qemu-kvm

14.编译qemu-kvm
[root@cyt code]# cd ~/my_kvm/code/
[root@cyt code]# git clone git://git.kernel.org/pub/scm/virt/kvm/qemu-kvm.git qemu-kvm.git
Initialized empty Git repository in /root/my_kvm/code/qemu-kvm.git/.git/

Resolving deltas: 100% (190470/190470), done.


[root@cyt qemu-kvm.git]# ./configure 


如果想支持spice 输入./configure --enable-spice


可能是失败，提示：
ERROR
ERROR: User requested feature spice
ERROR: configure was not able to find it
ERROR


用yum安装一下spice-server devel版本


执行make


最后看到输出  LINK  x86_64-softmmu/qemu-system-x86_64 这就是我们常用的qemu-kvm的命令行工具
全路径：/root/my_kvm/code/qemu-kvm.git/x86_64-softmmu/qemu-system-x86_64


15.安装qemu-kvm
 
[root@cyt qemu-kvm.git]# make install

done
for d in x86_64-softmmu; do \
make -C $d install || exit 1 ; \
        done
make[1]: Entering directory `/root/my_kvm/code/qemu-kvm.git/x86_64-softmmu'
install -m 755 qemu-system-x86_64 "/usr/local/bin"
strip "/usr/local/bin/qemu-system-x86_64"
make[1]: Leaving directory `/root/my_kvm/code/qemu-kvm.git/x86_64-softmmu'


验证安装结果：
[root@cyt qemu-kvm.git]# which qemu-system-x86_64
/usr/local/bin/qemu-system-x86_64
[root@cyt qemu-kvm.git]# which qemu-img
/usr/local/bin/qemu-img
