True, it's a bit confusing. The FAQ distributed with 2.6 specifically states the supported versions, with this caveat: "The Linux kernel versions are upstream kernel versions, so Linux kernels modified from the upstream sources may not build in some cases even if they are based on a supported version. This is most notably true of Red Hat Enterprise Linux (RHEL) kernels, which are extensively modified from upstream." https://github.com/openvswitch/ovs/blob/branch-2.6/FAQ.md#q-what-linux-kernel-versions-does-each-open-vswitch-release-work-with _______________________________________________ discuss mailing list [email protected] https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
