Failed to Deploy OVF package

ailed to deploy package: File ds:///vmfs/volumes/UUID/_deviceImage-0.iso was not found

While working on setup for a Custom version of our Exchange 2013/2016 Ultimate Bootcamp today, I came across a problem which is not new, but was new to me.

A colleague had saved some VMs to OVA format for deployment in a Master vApp.  As I went to deploy them, I received the following error message:

After doing some research, I came across a couple of articles.  Neither gave me what I needed, but through combining bits and experimenting, I found a solution.


   The VMs had ISOs attached to their CD-ROMs when the were exported to OVA format.
   The OVF file inside the OVA package has information about the attached ISO.



  1. Uncompressed the OVA file using either TAR on Linux/ESXi or 7-Zip on Windows.
  2. Located the OVF file which contains the configuration of the VM to deploy.

  3. In the VMname.OVF file, I searched for “vmware.cdrom.iso
  4. I replaced vmware.cdrom.iso with vmware.cdrom.remotepassthrough and saved the file.

  5. Calculated a new SHA1 hash for the updated VMname.OVF file using HashMyFiles (Download here:

  6. Edited the file and replaced the SHA1 hash for the VMname.ovf with the new one & saved the file.

  7. Deployed a new VM using the OVF file.
  8. Optionally you could repackage the OVF to an OVA using either OVFTool or TAR in a host.
    tar cvf VMname.ova VMname.ovf
    tar uvf VMname.ova *.mf *.vmdk

Another option would be to simply delete the MF file.  vSphere deployment of the OVF then wouldn't do a hash check at all and the install will complete as expected.  Your choice!
