Problems solved by technology

[0003] When the virtual private cloud (Virtual Private Cloud, VPC) where the migrated virtual machine is located has a lot of accessing virtual machines, it is very time-consuming to notify the Virtual Switch where each virtual machine is located to modify the forwarding rules. During this period, it may take seconds The notification convergence of the advanced time, so the virtual machines that are notified later may have the problem of delayed packet loss

Abstract

The invention discloses a message sending method after virtual machine migration, a message sending system after virtual machine migration, electronic equipment and a medium. And the original host machine modifies a first forwarding rule for the message of the virtual machine into a second forwarding rule for forwarding the message to the target host machine. According to the method disclosed by the invention, the problem of delay and packet loss caused by migration of the virtual machine under the large-scale VPC can be avoided.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a message sending method, system, electronic equipment and medium after virtual machine migration. Background technique [0002] Cloud host migration is a necessary technology in cloud computing. When a cloud host is migrated, the virtual switches (Virtual Switches) where all the virtual machines (VMs) communicating with this cloud host are located will be notified of the migration and the original settings will be modified. Forwarding rules. [0003] When the virtual private cloud (Virtual Private Cloud, VPC) where the migrated virtual machine is located has a lot of accessing virtual machines, it is very time-consuming to notify the Virtual Switch where each virtual machine is located to modify the forwarding rules. During this period, it may take seconds The notification convergence of the advanced time, so the virtual machines that are notified later may have the p...
