+For XenServer 6.5 or above, the kernel version naming no longer contains
+KERNEL_FLAVOR. In fact, only providing the `uname -r` output is enough.
+So, the final "rpmbuild" step changes to:
+
+ ```
+ KERNEL_UNAME=<`uname -r` output>
+ rpmbuild \
+ -D "kenel_uname $KERNEL_UNAME" \
+ -bb xenserver/openvswitch-xen.spec
+ ```
+
