The occupation of an HAVIP can be declared by the backend CVM, but you cannot manually bind HAVIPs to a specified server in the console (The experience is consistent with that of a traditional physical machine.).
The backend RS but not the HAVIP determines whether to migrate based on the configuration file negotiation.
Only supports VPC.
Heartbeat detection must be done by an application on the CVM, but not by the HAVIP, which serves only as a floating IP address declared by ARP (The experience is consistent with that of a traditional physical machine.).
