ovs-sandbox, for starting a sandboxed dummy Open vSwitch environment
usage: $0 [OPTION...]
If you run ovs-sandbox from an OVS build directory, it uses the OVS that
you built. Otherwise, if you have an installed Open vSwitch, it uses
the installed version.
These options force ovs-sandbox to use a particular OVS build:
-b, --builddir=DIR specify Open vSwitch build directory
-s, --srcdir=DIR specify Open vSwitch source directory
These options force ovs-sandbox to use an installed Open vSwitch:
-i, --installed use installed Open vSwitch
-S, --schema=FILE use FILE as vswitch.ovsschema
Other options:
-h, --help Print this usage message.
