Hi guys,

I use dynamic inventory azure\_rm and I have a problem with exluce\_host\_filters.

Some vms starts with xyz… and has tags. I need to filter the VMs starts with xyz but not has tags firewall and not working.

exclude\_host\_filters:

- location not in [‘eastus2’]
- “‘xyz’ not in name”
- “‘firewall’ in tags.product”

Other question,  
Is possible create inventory children in dynamic inventory, example?

conditional\_groups:  
vms:

- dev: “name.startswith(‘xyz\_dev’)”
- win: “‘windows’ in os\_disk.operating\_system\_type”
- lnx: os\_disk.operating\_system\_type == ‘linux’
