I havent tried it but you can try the steps in the below url
Yes. This was one of the resources I consulted.
did you try extracting the host profile from an existing host which is already part of dvs?
Yes. That's how the original Host Profile was created.
I'm having the same issue, we have 6x vDS Switches and host profile fails in 6.5 as well.... I was thinking of opening up a support ticket to see what is going on as I can't afford to spend a lot more time on this.... Has anyone found anything new on this?
