It would better to install to one utility container instead of utility_all: https://github.com/openstack/openstack-ansible/blob/master/playbooks/os-rally-install.yml

[Satish Patel (satish-txt)]

Agreed,

i think os_rally role should be optional because mostly it is use for stress testing.

A patch is now merged to master to allow the rally installation to be disabled https://review.opendev.org/c/openstack/openstack-ansible/+/840686

Hit the same issue on a Wallaby deployment.

Workaround has been backported to stable/wallaby and released with 23.4.0
