Hope this saves you an hour! I was attempting to use ovftool to export a VM from VMware vCenter vs. using the Web Client. I’m learning to use various CLI (command line interface) vs. UI. I spent a while and here is what I learned. Hope this helps.
#%5c is a escape character for \ when using Active Domain user authentication
#The password does not contain special characters
#The VM names don’t contain spaces (simple)
#The minimum vCenter permissions is export OVF App
C:\Program Files\VMware\VMware OVF Tool\ovftool –noSSLVerify “vi://domain%5cuser:SimplePassword@vcenter.example.com/DataCenter/vm/Templates/VMName-Not-Template-Prefer-No-Spaces-In-Name” C:\temp\Output.ovf
