vdeplug_restart

VDE connection self-restarting nested module

This nested module automatically restarts a VDE module in the event of a service failure.

This module of libvdeplug4 can be used in any program supporting VDE like vde_plug, vdens, kvm, qemu, user-mode-linux and virtualbox.

install vdeplug_restart

Requirements: vdeplug4.

vdeplug_restart uses cmake, so the standard procedure to build and install this vdeplug plugin module is the following:

$ mkdir build
$ cd build
$ cmake ..
$ make
$ sudo make install

usage examples (tutorial)

The following examples are VNLs (Virtual Network Locator) to be used with programs supporting vde as specified by the syntax of those programs.

restart the cable to the switch

restart://{vde:///tmp/sw}

This configuration checks every 20 seconds whether the connection to the switch is operational. If a failure is detected, the module attempts to reconnect to the switch every 20 seconds

restart the cable to the switch (3 seconds polling)

restart://3{vde:///tmp/sw}

This is equivalent to the previous example, except that the polling period for checking the service and attempting reconnection is 3 seconds instead of the default 20 seconds.

See the man page (libvdeplug_restart) for more information.
