How do I set target VM hostname when deploying OVA?

I'm deploying OVA files to a vCenter using ovftool; it's working perfectly, but I want to go the extra mile and automatically set the hostname of the VM after it is deployed.

I found a reference to a 'hostname' property (--prop:hostname=myvm.example.com), but it doesn't actually work

Here's my command  line

ovftool --lax --acceptAllEulas --datastore=MySAN --overwrite --powerOn --vmFolder=TestFolder --diskMode=thin --powerOffTarget --prop:hostname=myvm.example.comhttp://myurl.com/path/input.ova vi://vcenteruser:password@mycenter.example.com/MyDC/host/MyD/Resources/OVFTest

So what is the proper way to do this?
