I was trying to build the Open vSwitch kernel module(using \
openvswitch-2.0.0.tar.gz<http://openvswitch.org/releases/openvswitch-2.0.0.tar.gz>) \
on RHEL 7 Beta . My kernel version is 3.10.0-54.0.1.el7.x86_64 .


rpmbuild -bb  -D "kversion 3.10.0-54.0.1.el7.x86_64" -D "kflavors default debug \
kdump"  rhel/openvswitch-kmod-rhel6.spec

I get the following error when the above command is executed -
