Do you confirm that copying from /opt/opencpi/cdk/zed/sdcard-xilinx13_4/* is correct?
Media is write-able - this issue with sym links is a VM problem and I wondered if you had a simple workaround. I'll either chase it down or go to a native linux machine to copy it.
Sincerely,

Subject: Re: [Discuss OpenCPI] Programming SD card for Zed
This is a source-install vs. rpm-install issue, and the docs should be clearer about this distinction. This is in fact a current work item.
If looks like the /media was mounted read-only?
Both RPM and source installations should allow you to do this.
Not sure what the "VM symbolic link issue" is. Other email?
