US 10,320,895 B2 · Live migration of load balanced virtual machines via traffic bypass

Abstract

Methods, systems, and devices are described herein for managing a load balancer bypass between two virtual machines through live migration of at least one of the virtual machines. In one aspect, a load balancer bypass may be established between a source virtual machine associated with a source host and a destination virtual machine associated with a destination host. The source virtual machine identification information, source host identification information, destination virtual machine identification information, and destination host identification information may be associated with an indication of whether the bypass is active, for example, in a bypass data structure. Upon a determination that live migration of at least one of the source virtual machine or the destination virtual machine has been completed to a third host, the bypass data structure may be updated with identification information of the third host to maintain the load balancer bypass after completion of the live migration.

Dependent claims

A data center, the data center comprising:

a source host device, a destination host device, and a third host device;
a plurality of virtual machines, wherein a source virtual machine of the plurality of virtual machines is provided by the source host device and a destination virtual machine of the plurality of virtual machines is provided by the destination host device;
and
a load balancer communicatively coupled with the source host device, the destination host device, the third host device, and the plurality of virtual machines, wherein the load balancer is configured to:
establish a load balancer bypass between the source virtual machine and the destination virtual machine;
associate source virtual machine identification information, source host identification information, destination virtual machine identification information, and destination host identification information with an indication in a bypass data structure, wherein the indication indicates whether the load balancer bypass is active;
determining that live migration of at least one of the source virtual machine or the destination virtual machine has been completed to the third host device;
and
updating the bypass data structure with identification information of the third host device to maintain the load balancer bypass after completion of the live migration.
