Title: Live Migration for the OpenShift Provider (Epic MTV-2040)

The Live Migration epic aims to enable seamless, intra-cluster node-to-node live migration of VMs within OpenShift clusters, ensuring high availability. MTV will create and map resources, initiating the migration between clusters, while the Migration Toolkit for Virtualization and OpenShift Provider handle the actual migration.

Currently, the epic is in progress, with the main related issue, MTV-2040, undergoing development. The implementation is dependent on CNV 4.20, which is expected to deliver their parts by the target release, version 2.10.0.

Testing is yet to be finalized, with a meeting scheduled between team members to discuss the testing strategy. Potential challenges include ensuring seamless integration with the Migration Toolkit and optimizing resource utilization.

The epic is also linked to several child issues, including design, implementation, and spike tasks, as well as a related documentation epic. Progress is being made, and the team is working towards a successful live migration solution for OpenShift clusters.

Goal

Today MTV can already migrate (warm, cold) VMs from OpenShift to another OpenShift.

In future - with this epic done - MTV can also live migrate a VM from OCP to OCP, Live migration as in the intra cluster node to node live-migration.

User Stories

• As a cluster administrator, I want MTV to live migrate a VM from OCP to OCP, so that the VM will never be down.

Non-Requirements

• MTV will not do the live migration itself, MTV is only a) creating and mapping resources from src to dst and b) kicking of the live migration between the two clusters. CNV is then doing the live migration
