Hi indian
Before all thanks for your kind reply.
If you read my post (I hope it is clear enough), basically I need to get
ONLY the mac address of a specific VM "testvm", put it in a variable and,
using the regex, add it in a file.
Do you have a vsphere to test my playbook?
Please note that i did lot of internet searches and it seems that the hard
part is to make working the folowing code that should do the trick:
debug: msg="{{ vm_guest_facts.virtual_machines['testvm'].mac_address }}"
Best
Marco
