I build my opennebula for internal usage.
I have been use other cloud technology, it having EIP function.
With opennebula i see Alias IP look for same of EIP. But when i deploy follow Virtual Network Functions (VNF) and Virtual Router — OpenNebula 6.6.1 documentation but Alias external not work.
VM can ping and resolve DNS via vRouter, but when attach Alias IP, that IP not work.
