[test.log](/uploads/174db2ace468bd9f0ec3ab14de524217/test.log)
Steps to reproduce:
1. create empty vmdk file

./qemu-img create -f vmdk -o adapter_type=lsilogic,subformat=streamOptimized empty.vmdk 1G

2. add empty file info  to  ovf file
<File ovf:href="empty.vmdk" ovf:id="file2"/>

3. import it to vmware workstation
Additional information:
If i write some data to empty vmdk file, it can import successfully.  The reson: qemu only write metadata for empty vmdk file, but the ovftool need read more data and it cann't read more.
we can write one sector zero data after the metadata, ovftool work well.
