29.3. A warning message is displayed while installing the para-virtualized drivers on Red Hat Enterprise Linux 3
Installing the para-virtualized drivers on a Red Hat Enterprise Linux 3 kernel prior to 2.4.21-52 may result in a warning message being displayed stating the modules have been compiled with a newer version than the running kernel.
This message, as seen below, can be safely ignored.
The important part of the message above is the last line which should state the module has been loaded with warnings.
