HP ILO utility for Ubuntu - hponcfg fails due to missing hp-ilo package

The hp-ilo package doesn't need to exist anymore on modern Linux systems, since the driver is now part of the mainline kernel (since 2.6.33 or thereabouts).

It should not be necessary to do anything with a standard kernel on any mainstream Linux distribution, since they all build the hpilo module and make it available by default.

However, you seem to have a nonstandard kernel from a third party. In this case, you may have to manually load the module:

modprobe hpilo

Or, you may find that the people who built the kernel (Zetavault?) did not actually build in this module. In this case you need to take up the issue with them.
