Static IP retention for multi-homed VMs on migration

Abstract:

An illustrative embodiment disclosed herein is a method, by a migration virtual machine, including determining whether a first target network interface card is configured by dynamic host configuration protocol and sending a first address resolution protocol request for a first source Internet Protocol gateway to the first target network interface card. Sending the first address resolution protocol request is based on determining that the first target network interface card is not configured by dynamic host configuration protocol. The method further includes determining whether the first target network interface card responds to the first address resolution protocol request of the migration virtual machine and applying an Internet Protocol configuration of a first source network interface card to the first target network interface card. Applying the Internet Protocol configuration is based on receiving a response from the first target network interface card to the first address resolution protocol request of the migration virtual machine.
