I just found!!
All my servers are in French, and the search criteria for VM are in English, modifying the criteria it works.
Info for the changes I made:
Line 9835 of \Dell\SysMgt\Essentials\configuration\DataFormatterFiles\Insrtuctions\FormatInstructions.xml
change :
<variable name="PPA::Expression" type="PPA::String">(contains (KEY(31f854cd-8ec8-45c5-91a7-197a5be99948),"Virtual"))</variable>
To :
<variable name="PPA::Expression" type="PPA::String">(contains (KEY(31f854cd-8ec8-45c5-91a7-197a5be99948),"Virtual") || contains (KEY(31f854cd-8ec8-45c5-91a7-197a5be99948),"virtuel"))</variable>
and
Line 9856 (same file)
change :
<variable name="PPA::Expression" type="PPA::String">(contains (KEY(31f854cd-8ec8-45c5-91a7-197a5be99948),"Host"))</variable>to :
<variable name="PPA::Expression" type="PPA::String">(contains (KEY(31f854cd-8ec8-45c5-91a7-197a5be99948),"Host") || contains (KEY(31f854cd-8ec8-45c5-91a7-197a5be99948),"informatique"))</variable>
It works for me.
If you can tell the issue to software developper to fix in futur version, that will help...
Thank you for everything.
