先卸載qemu-kvm
yum –y remove qemu-kvm
源碼地址：http://wiki.qemu.org/Download
下載源碼
wget http://wiki.qemu-project.org/download/qemu-2.8.0-rc0.tar.bz2
安裝依賴包
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
編譯安裝
tar xf qemu-2.8.0.tar.bz2
cd qemu-2.8.0
./configure --enable-usb-redir --enable-libusb --enable-spice --enable-uuid --enable-kvm --enable-bzip2 --prefix=/usr/local/qemu --enable-linux-aio --enable-system
make && make install
編譯完成之後 做鏈接
# ln -s /usr/local/qemu/bin/qemu-system-x86_64 /usr/bin/qemu-kvm
# ln -s /usr/local/qemu/bin/qemu-system-x86_64 /usr/libexec/qemu-kvm
# ln -s /usr/local/qemu/bin/qemu-img /usr/bin/qemu-img
查看當前qemu版本,可以看到當前版本爲2.8
qemu-img --version
qemu-kvm –version
