+# Kernel Compatibility: Ensure kernel-devel matches your running kernel (uname -r). If mismatched, update the kernel or install the correct kernel-devel package.
+# DPDK (Optional): For high-performance setups, install dpdk and dpdk-devel, then add --with-dpdk to ./configure.
+# Troubleshooting: Check logs in /var/log/openvswitch/ if services fail to start. Ensure the user has permissions (e.g., sudo usermod -aG openvswitch $USER).
+# Source: The tarball is downloaded from openvswitch.org, and the Git repository is at github.com/openvswitch/ovs, tag v3.5.0
