Installing VMware Cloud Foundation (VCF) 9 in a lab often means using less than ideal hardware configurations. In my case, I have ASUS Intel NUCs that have only one physical NIC for an uplink. Recommendations dictate you should have at least two for redundancy and the VCF Installer checks this. If you have less than two uplinks, VCF Installer will block the deployment. There is a way around this and it is simple.
I received the following details when the VCF Installer was validating existing components:
VcManager <vCenter FQDN>: Found less than two uplinks for the DVS <distributed virtual switch name>
Remediation: Please ensure a minimum of 2 configured uplinks for each DVS.
This is because I had only one uplink configured for the DVS. Getting around this was easier than I thought. I assumed I needed two physical NICs on each host. It turns out I only need two uplinks configured--even if one of the uplinks does not have a physical NIC backing.
I proceeded to the Network section of the vSphere Client, right-clicked the DVS, clicked Settings, and then Edit Settings.
I clicked Uplinks in the Distributed Switch - Edit Settings popup window, added an uplink, and clicked OK.
I re-ran the VCF Installer validations and everything succeeded.
