# MURANO_RABBIT_VHOST allows to specify a separate virtual host for Murano services.
# This is not required if all OpenStack services are deployed by devstack scripts
#   on a single node. In this case '/' virtual host (which is the default) is enough.
# The problem arise when Murano installed in 'devbox' mode, allowing two or more
#   devboxes to use one common OpenStack host. In this case it's better devboxes
#   use separated virtual hosts, to avoid conflicts between Murano services.
# This couldn't be done using exitsting variables, so that's why this variable was added.
