My experience is that this nothing more than the dumb way VMW shows progress. When you are doing an export, it is usually 2 files, OVF and VMDK. Once VMW exports the OVF at a massive 20KB, it thinks it is 50% done. 1 of 2 files, right? Not so. The VMDK can be hundreds of GB. And yet that is not reflected in the progress. Look to see if you have a download indicator moving in the top right of your browser. Go to the browser download location. You should see the OVF and a CRDOWNLOAD file that continually increases in size. Once the download completes, it will be renamed to the appropriate VMDK. If the download fails for some reason prior to completion due to hard drive or network error, the CRDOWNLOAD will be unusable. You can try and resume depending upon your browser.
