Missing libmi.so when using GuestConfiguration cmdlets on many Linux distros - Broken OMI dependency.

[AhmedBM]

Details of the scenario you tried and the problem that is occurring

When trying to apply a machine configuration package using the GuestConfiguration cmdlets as seen in How to test machine configuration package artifacts on any of the supported distributions the following error occurs:

It seems the omi libraries needed by PowerShell DSC are not being found. Upon further inspection, it seems the default search path is not included which is why this issue occurs. Simply adding /opt/omi/lib/ to the search path fixes this problem.

Suggested solution to the issue

Add the OMI libraries to the system library search path

The DSC configuration that is used to reproduce the issue (if applicable)

# OMI install its libs in /opt/omi/lib/, include in search path
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/omi/lib/
