Error: Failed to deploy OVF package: The task was canceled by a user

This error occurs when you export a virtual machine from your ESXi or vCenter server as OVA or OVF template with an ISO file mounted as CD/DVD drive. This setting is saved in the configuration file inside the OVF package. Please note that once you unpack the OVF file, delete .mf file since it contains the SHA1 checksum of the OVA package and cannot be used again. Now edit the .ova file, which is basically the XML file, and look for the following line:

<rasd:ResourceSubType>vmware.cdrom.iso</rasd:ResourceSubType>

Now replace the word iso with ATAPI so the line reads

<rasd:ResourceSubType>vmware.cdrom.atapi</rasd:ResourceSubType>
