Hi Dwayne

Which version of FortiOS are you installing?

Try follow this guide.

And make sure the disks are configured exactly as mentioned.

Version 7.4.8 is working fine for me in Proxmox 9.0.3 using the provided tutorial. However, version 7.6.4 gives me the same error as you.

I am looking to use the new feature in Proxmox 9 that allows for direct import of Fortinet images.  I can see bits and pieces of it in the GUI, but not seeing how I get the images into the ISO storage volume?  Is there any documentation in the wild?

One must enable import on the datadrives and then qcow2 files can be uploaded.  I have not figured out the drive assignment part yet.

When you are building the VM, delete the initial disk, and then click on "Import" instead of "Add".  Choose your Import Storage (wherever you saved the .qcow file you uploaded i.e. "local"), the image file, and the Target Storage (i.e. local-lvm)
