your syntax is correct but try getting rid of the extra space after both instances of the "--net:" and see, that should work.
--net:"Out of Band Management"="VM Network" --net:"Public"="VM Network"
Thank you very much for your advice!
I followed what you recommended and a different error message is thrown now which is "Error: Config::View::Set failed. Node already has a child. Completed with errors".
That will be my next fun to take care of.
Can you please extract the .ovf file from the OVA archive, and attach it to a reply post?
It looks like there was some issue while installing ovf tool on my PC.
I installed ovf tool 4.3.0 U3 at first so I removed it and installed ovf tool 4.3.0.
Then, it worked.
