In the case when i need to add physical vmnic to an ESX. the existing vswitch will show as vswitch0 and the new one will show as vswitch1. in this case do I need to manually move the existing VMs from Vswitch0 to Vswitch1? or for instance when adding new VMs,do I need to specify to which vswitch they should belong to.? OR the Network load will automatically be shared between the 2 vmnics .
