vMotion migration [175137030:263017964320432507] failed to get DVS state in the restore phase from the source host <HOST_IP>
Migrations triggered by users manually in the vCenter for the same source and destination host will be successful.
There is a datapath regression issue that omits the vnicIsConnected field during the Workload Migration actions in ESXi 8.x that will cause the destination host to fail to receive the correct NIC data to boot the VM at the destination. This causes the migration to fail back to the source host.
Engineering is aware of the issue and is actively working on a resolution.
