Hello, I'm getting the alert in the image attached when trying to create my first Provider VDC. I am running vCenter 5.5 and vCloud director 5.5. I thought that this error could be because I do not have the vCloud agent installed, however it appears to indicate in the link above that the vCloud agent is no longer required unless the host must support creation of vCloud network isolation based (VCDNI), so I don't think that not having the agent is my issue.
I don't believe that I still require the vCloud agent to be installed as part of my autodeploy image (please correct me if I'm wrong). I'm wondering if I require a minimum of two ESXi hosts in order to get vCloud working properly. Could someone confirm is two hosts are required?
