Hello @kevin s
The virtual adapters added to the Server 2022 hosts with IPv4 and IPv6 enabled but no IP assigned are expected if you're using VLAN-based independent logical networks in SCVMM. These virtual adapters are used to represent the VLANs on the host and will not have an IP address assigned to them since they are virtual network adapters used only for network communication between the virtual machines and the physical switch.
Regarding the cluster validation wizard error that the virtual adapters won't be added because they have an APIPA address, this is also expected since the virtual adapters are not assigned an IP address. The cluster validation wizard verifies that the physical network adapters on the cluster nodes are configured with a valid IP address and can communicate with each other.
If you have configured the logical network and virtual switches correctly in SCVMM and the virtual machines are able to communicate with each other and with the outside world, then you should not be concerned about the APIPA error in the cluster validation wizard. The virtual adapters are not used for cluster communication, and as long as the physical network adapters on the cluster nodes are configured correctly, the cluster should function properly.
However, if you're experiencing issues with communication between the virtual machines or with the outside world, you may want to double-check your logical network and virtual switch configurations in SCVMM to ensure that they are set up correctly.
