##### SUMMARY
<!-- Explain the problem/feature briefly -->
Related to #4022
After setting up a Basic Zone with a single host (management + agent), I see
host resources, but no Secondary Storage available for CS.
I'm using a NFS backed Primary and Secondary Storage and set it up according
to [this](https://rohityadav.cloud/blog/cloudstack-kvm/) manual.
I installed the SystemVM template with the following command:
```
wget
http://packages.shapeblue.com/systemvmtemplate/4.15/systemvmtemplate-4.15.1-kvm.qcow2.bz2
/usr/share/cloudstack-common/scripts/storage/secondary/cloud-install-sys-tmplt \
-m /export/secondary -f systemvmtemplate-4.15.1-kvm.qcow2.bz2 -h
kvm \
-o localhost -r cloud -d cloud
```
Here's the log exert from management-server.log
```
