Create OVF with flat vmdk

Hey,

I'm trying to build a utility that builds an OVF, given a flat.vmdk and a .vmdk with the descriptor. But I've found that only streamOptimized disks will export properly, however they only take embedded descriptors. I'm using VSphere 4 to deploy an ovf.

In the ovf, I have the disk format to be ovf:format="http://www.vmware.com/interfaces/specifications/vmdk.html#streamOptimized". This works perfectly fine until VSphere gets to reading the vmdk file where it gives the error message "Error uploading file C:\path\to\scsi0_0.vmdk to server. I/O exception while reading VMDK header", where the header is,

I guess my question is, does deploying ovfs support any other format other than streamOptimized where I can use a flat.vmdk and a .vmdk?

Thank you,

Kyle
