[1] Install Trove services on Network Node.
# install from Xena, EPEL, PowerTools

[root@network ~]#
dnf --enablerepo=centos-openstack-xena,powertools,epel -y install openstack-trove-api openstack-trove-conductor openstack-trove-taskmanager python3-troveclient
[2] Configure Trove.

[root@network ~]#
chgrp trove /etc/trove/*.conf

[root@network ~]#
su -s /bin/bash trove -c "trove-manage db_sync"

[root@network ~]#
systemctl enable --now openstack-trove-api openstack-trove-taskmanager openstack-trove-conductor
[3] If Firewalld is running, allow service ports.
[root@network ~]#
firewall-cmd --add-port=8779/tcp

success
[root@network ~]#
firewall-cmd --runtime-to-permanent

success
[4] Verify Trove status on Control Node. It's OK if no errors are shown.
[root@dlp ~(keystone)]#
dnf --enablerepo=centos-openstack-xena,powertools,epel -y install python3-troveclient
