ovs-ctl(8) Open vSwitch Manual ovs-ctl(8) NAME ovs-kmod-ctl - OVS startup helper script for loading kernel modules SYNOPSIS ovs-kmod-ctl insert ovs-kmod-ctl remove ovs-kmod-ctl help | -h | --help ovs-kmod-ctl --version ovs-kmod-ctl version DESCRIPTION The ovs-kmod-ctl program is responsible for inserting and removing Open vSwitch kernel modules. It is not meant to be invoked directly by sys- tem administrators but to be called internally by system startup scripts. The script is used as part of an SELinux transition domain. Each of ovs-kmod-ctl's commands is described separately below. The ``insert'' command The insert command loads the Open vSwitch kernel modules, if needed. If this fails, and the Linux bridge module is loaded but no bridges ex- ist, it tries to unload the bridge module and tries loading the Open vSwitch kernel module again. The ``remove'' command The remove command unloads the Open vSwitch kernel module (including the bridge compatibility module, if loaded) and any associated vport modules. EXIT STATUS ovs-kmod-ctl exits with status 0 on success and nonzero on failure. The insert command is considered to succeed if kernel modules are al- ready loaded; the remove command is considered to succeed if none of the kernel modules are loaded. ENVIRONMENT The following environment variables affect ovs-kmod-ctl: PATH ovs-kmod-ctl does not hardcode the location of any of the pro- grams that it runs. ovs-kmod-ctl will add the sbindir and bindir that were specified at configure time to PATH, if they are not already present. OVS_LOGDIR OVS_RUNDIR OVS_DBDIR OVS_SYSCONFDIR OVS_PKGDATADIR OVS_BINDIR OVS_SBINDIR Setting one of these variables in the environment overrides the respective configure option, both for ovs-kmod-ctl itself and for the other Open vSwitch programs that it runs. FILES ovs-kmod-ctl uses the following files: ovs-lib Shell function library used internally by ovs-kmod-ctl. It must be installed in the same directory as ovs-kmod-ctl. EXAMPLE ovs-kmod-ctl isn't intended to be manually executed. However, the fol- lowing examples demonstrate loading the kernel modules. ovs-kmod-ctl insert Attempts to insert the Open vSwitch kernel modules. ovs-kmod-ctl remove Attempts to remove the Open vSwitch kernel modules.
