ESX(i) vSwitches can't form loops.＊
Running etherchannel with IP-hash load balancing is nothing special and shouldn't cause any problems if properly configured, just make sure you adhere to the supported configurations:
＊Unless you deliberately configure a VM with multiple vNICs in a very strange way to bridge between adapters and act as the loop-link.
