We can do something like:

- hosts: group1  
&nbsp;&nbsp;roles:  
&nbsp;&nbsp;&nbsp;&nbsp;- role1

- hosts: group1:group2  
&nbsp;&nbsp;roles:  
&nbsp;&nbsp;&nbsp;&nbsp;- role2

- hosts: group2  
&nbsp;&nbsp;roles:  
&nbsp;&nbsp;&nbsp;&nbsp;- role3

etc, in a playbook. Would it be somehow possible to assign hosts "per role"? Something like:

- hosts: group1  
&nbsp;&nbsp;roles:  
&nbsp;&nbsp;&nbsp;&nbsp;- { role1, hosts: group3 }  
&nbsp;&nbsp;&nbsp;&nbsp;- { role2 }  
&nbsp;&nbsp;&nbsp;&nbsp;- { role3 }  
&nbsp;&nbsp;&nbsp;&nbsp;- { role4, hosts: group4 }

? The above doesn't seem to work 😉

I’m not sure I understand what it is your trying to do here…

If you are trying to have some hosts execute another group’s role, you can use **includes**.  
Otherwise, if you can explain why you are nesting **group3/4** under **roles** when you have **group1** set as **hosts**.
