ovftool sanfs://..../linux.iso was not found

Hi,

I'm trying to convert VM into ovf. But ovftool fails with the message:

./ovftool --powerOffSource vi://administrator:xxxxx@host/?ip=192.168.1.22 myovf.ovf
Opening VI source: vi://administrator@host/
Powering off VM: 0593498732-VM_Name
Error: File sanfs://vmfs_uuid:3c3693e8-f77a642a-1910-5c6bdcb26d3a/packages/4.1.0/vmtools/linux.iso was not found

Could you please help me with the issue above?

Thanks,
