Via Xen Orchestra
Xen Orchestra is the de facto standard client to manage your XCP-ng hosts.
Quick’n dirty
Here is the easiest way to achieve it. In Xen Orchestra, left main menu, go into “+ New”, then “Storage”. Select your host, then fill the form:

- Host: the host you want to create the local ISO SR
- Name/description: the name label and description of your ISO SR (you can change it anytime later)
- Storage type: ISO SR/Local
- Path:
/media
Click on “Create” and you are done:

Upload your ISO
Now you can import your favorite distro ISO via Xen Orchestra directly: in the left menu, go in “Import”, then “Disk”, select your freshly created ISOs SR and then drag & drop your ISO:

ℹ️
If you want to “refresh” when you uploaded an ISO, go in the SR view and click on “Rescan all disks” button (top-right in the action bar).
