OracleVM discovery issues

Primoz

Hello,

 I'm trying to add OracleVM to lpar2rrd (installed appliance, update to latest version).
I manually executed /home/lpar2rrd/lpar2rrd/load_oraclevm.sh to see what is going on:
It goes through "Updating server RRD", "Updating vm net RRD", "Creating RRD" and "Updating server net RRD". Then it gives an error, continued with a listing:

orvm-json2rrd.pl : status 0, Thu Aug 20 08:15:13 CEST 2020

An error occured in lpar2rrd, check /home/lpar2rrd/lpar2rrd/logs/error.log-oraclevm and output of load_oraclevm.sh

$ tail -927 /home/lpar2rrd/lpar2rrd/logs/error.log-oraclevm

There is a bunch of those FREE_MEMORY related messages, then it continues with:

Use of uninitialized value $RRDp::error_mode in string eq at /usr/lib64/perl5/vendor_perl/RRDp.pm line 168.

And I suppose there's such a chunk of log for each disk on VMs.
The result is that VM's don't have any data about disks.

Any help appreciated.
Kind regards,
