• 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 VPC instances are supported, and the basic network is not supported.
• 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.)
