Parallels Cloud Server command line tools and services are missing after the installation of a PCS host only with a "Chunk Server" or "Metadata Server" role.
If a server is installed only with a CS/MDS role (no Client Role), it is not expected to host containers/VMs.
Parallels Cloud Storage roles do not provide any PCS-related tools and services.
When it is necessary to turn a server into a fully functional client server, install the necessary packages via
# yum groupinstall "Parallels Containers" "Parallels Hypervisor" "Parallels High Availability"
To learn more about these groups and the packages they contain, check their Group Info:
# yum groupinfo "Parallels Containers" # yum groupinfo "Parallels Hypervisor" # yum groupinfo "Parallels High Availability"
After that start
# service parallels-server start
