[Xymon] Client test script fails when run by xymon, works when run manually

[Jeremy Laidman]

A few ideas:

Su to the xymon user first, then run bbcmd.

Run the command "env > /to/env" in the script and compare the file between
xymon running and you running.

Add "set -x" before the vboxmanage command and "set +x" after.

Cheers
Jeremy
