ovs-kmod-ctl version
The ovs-kmod-ctl program is responsible for inserting and
removing Open vSwitch kernel modules. It is not meant to be
invoked directly by system 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 loads the Open vSwitch kernel modules, if
needed. If this fails, and the Linux bridge module is loaded but
no bridges exist, it tries to unload the bridge module and tries
loading the Open vSwitch kernel module again.
The remove command unloads the Open vSwitch kernel module
(including the bridge compatibility module, if loaded) and any
associated vport modules.
ovs-kmod-ctl exits with status 0 on success and nonzero on
failure. The insert command is considered to succeed if kernel
modules are already loaded; the remove command is considered to
succeed if none of the kernel modules are loaded.
The following environment variables affect ovs-kmod-ctl:
PATH ovs-kmod-ctl does not hardcode the location of any of the
programs 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.
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.
ovs-kmod-ctl isn't intended to be manually executed. However,
the following 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.
