以 Running hypervisor: QEMU 1.5.3 的版本作为标准，可见是不能满足版本需求的。

解决

升级 QEMU 至 >= 2.5.0。

yum -y install gcc gcc-c++ automake libtool zlib-devel glib2-devel bzip2-devel libuuid-devel spice-protocol spice-server-devel usbredir-devel libaio-devel

wget https://download.qemu.org/qemu-3.1.0-rc0.tar.xz
tar xvJf qemu-3.1.0-rc0.tar.xz
cd qemu-3.1.0-rc0
./configure
make && make install
