openvswitch-2.9.0.安装过程：
yum -y install openssl-devel wget kernel-devel selinux-policy-devel python-sphinx
yum groupinstall "Development Tools"
下载openvswitch.org
tar xfz openvswitch-2.9.0.tar.gz
mkdir -p ~/rpmbuild/SOURCES
sed 's/openvswitch-kmod, //g' openvswitch-2.9.0/rhel/openvswitch.spec > openvswitch-2.9.0/rhel/openvswitch_no_kmod.spec
cp openvswitch-2.9.0.tar.gz ~/rpmbuild/SOURCES/
rpmbuild -bb --without=check openvswitch-2.9.0/rhel/openvswitch_no_kmod.spec
yum localinstall ~/rpmbuild/RPMS/x86_64/openvswitch-2.9.0-1.x86_64.rpm
