3.解压

tar -jxvf qemu-2.4.1.tar.bz2

4.安装

./configure
make
make install
# 觉得make 慢的可以使用下面命令
make -j4 #让make最多允许4个编译进程同时执行
make install

编译完成之后 做链接

默认安装在/usr/local/bin/

ln -s /usr/local/bin/qemu-system-x86_64 /usr/bin/qemu-kvm
ln -s /usr/local/bin/qemu-system-x86_64 /usr/libexec/qemu-kvm
ln -s /usr/local/bin/qemu-img /usr/bin/qemu-img
