Hi guys. Been trying to import my Harvard CS50 appliance but to no avail. Would appreciate any help on this.

It would be helpful if you zipped and posted the OVF descriptor on its own, since I don't fancy a 1GB download over my connection.
However, my first reaction is, assuming the message means what I think it does, that disks in an appliance set should not be difference images, and therefore should not require a parent. The whole idea of an "appliance" is that it's stand alone and portable.

Hey there,
Just wondering if you found a solution to import the appliance, I'm having the same problem, however I'm working on a Macbook, version 10.9 and running on OS X Mavericks.
Any idea how I can solve this problem??

No, it is not a Mavericks problem. I see the same error in both Windows 7 and Windows 8.1 with Vbox 4.3.0 . Either there is something wrong with the Harvard ovf or something has changed in VirtualBox.

I downloaded it trying to troubleshoot
another post by "CrownJ"/"EsBee" (is it actually the same user?). No need to zip it, it's very small.

The OVF looks all messed up to me. I may not be reading it correctly, but it seems to be creating a bunch of items not identified properly, plus references to items (e.g. 4 and 5) which don't exist. I would report these problems back to whoever distributes the VM.
If I desperately needed to get the VM running I would first unpack the VMDK by cloning to --format VDI, then I'd manually build the VM around the VDI. It seems to expect 512MB RAM (so I assume it's a 32bit Fedora), CD connected to IDE, and the VDI connected to SATA. PIIX4 chipset. NAT network mode. Everything else is probably unimportant. For Fedora you should probably turn IOAPIC on.

Yes guilty, CrownJ that's me
As for ovf descriptor, see attached. Any ideas how I can fix it? Many thanks in advance~

Skip importing. Instead, create a new ubuntu host, and when prompted for a virtual hard drive, select the downloaded vmdk file. It should boot up just fine.

It may boot up, but it's a stream optimized (a.k.a compressed) disk image, hence it will work as an immutable drive plus reads from it will be horribly slow.
A better way is to clone the disk first to VDI format, then build your VM around the clone. I mentioned this already, in the second para of my previous message.

The .ovf file has an error.
XML Item element at line 117 refers to a Parent that does not exist in the file.
Should be 3, not 4.
<rasd:Parent>3</rasd:Parent>
3 is the InstanceID of the IDE controller.

Navigate to the cs50-appliance.ovf file. Right click and open the file with a text editor (Sublime Text, Text Wrangler, etc.). For me it was on line 128 but the line number is referenced in the error I believe.

Solved the problem for me.

Thanks universalshrew - that worked for me, too. Any hints on why this is? Many thanks!

Excuse my ignorance, but could anyone tell me which version of a text editor I would need to download to accomplish this task, i.e. Windows or Linux? I'm running Windows on my pc, and have a virtual appliance with Linux (Fedora). This code is (I guess) Linux.

One would think any text editor would do on Windows or Linux. It opens with TextEdit on OSX.
