The command above will start other OVS services:
|
|
|
|
systemctl status ovs-vswitchd ovsdb-server
|
|
|
|
Log out of your current shell session, then log back in:
|
|
|
|
logout
|
|
|
|
Run the ovs-vsctl show command to verify the Open vSwitch (OVS) version:
|
|
|
|
$ ovs-vsctl show
|
|
8d2d42ed-88e7-45bc-b2d2-eb43e25763b1
|
|
ovs_version: "3.5.0-1.el8"
|
|
# 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
