Feature Overview

The goal of this feature is to extend the os_migrate tool to facilitate the migration of virtual machines (VMs) from VMware to Red Hat OpenStack Platform 17.1 and Red Hat OpenStack Services on OpenShift (RHOSO) 18 with minimal downtime. 

Goals

• Benefit to Users: This feature will benefit system administrators and IT professionals responsible for managing cloud infrastructure by providing a  method to migrate VMs from VMware to RHOSO, minimizing downtime and simplifying the migration process.
• Current State vs. Future State: Currently, VM migration from VMware to RHOSO may involve multiple manual steps and significant downtime. With this feature, the process will be automated and optimized, resulting in less manual intervention and reduced service interruption.

Requirements

Use Cases

• User Interaction: System administrators will use the Red Hat OpenStack Vmware Migration tool  new feature to initiate and complete the migration of VMs from VMware to RHOSP 17.1/RHOSO.
• Target Users: The initial audience for this feature is Red Hat Services consultants and architects. It is also relevant for IT professionals responsible for managing virtualized environments and migrating workloads to cloud infrastructure.
• Integration with Ansible Automation Platform: migrations are triggered via an Ansible Job running in an Ansible Automation Platform Execution Environment. Ansible Jobs will use the Red Hat OpenStack Vmware Migration toolkit ansible collection from the Ansible Automation Hub.

Out of Scope

• Pre-workload migration tasks such as copying networks, security groups, and images are out of scope for this feature.  We could potentially leverage the work from vmware to OCP virtualization solution to gather the network information facts from the source vSphere cluster: AAP-23015  https://gitlab.consulting.redhat.com/redhat-cop/vmware-openshift-virt-migration/vmware_migr[…]mware_migration/roles/tor_switch_gather?ref_type=heads  and then manually map it to OSP resources.

Assumptions

• Prerequisites and dependencies, such as access to both VMware and RHOSO environments, are in place.
• Necessary hardware and software resources are available for the migration process.

Documentation Considerations

• Reference Material: Provide the following documentation:
  • Install Red Hat OpenStack Vmware Migration toolkit
  • Vmware Prerequisites:
    • Vmware Privileges
    • Creating a VMware role to grant RHOVMT privileges
    • Importing VDDK image
  • Red Hat OpenStack prerequisites:

• • • RHVMT Conversion host deployment
  • Ansible Automation Platform prerequisites:

• • • Ansible Execution Environment creation
      • incl. vmware libs inclusion
  • Migrating Virtual Machines using Ansible Automation Platform

RHVMT performance recommendations

• • Troubleshooting

• Educational Material
  • Slides from the documentation mainly about RHVMT architecture, installation and troubleshooting
    • Deep-dive slides about how data transfer occurs between vCenter and OpenStack

• Success Criteria: Success is defined by the ability to migrate VMs from VMware to RHOSO with minimal downtime and user intervention.
• Doc Impact: This feature will require a new documentation.

Interoperability Considerations

• Impact on Other Products: Ensure compatibility with other products and versions in the portfolio.
• Test Scenarios: Develop and factor interoperability test scenarios to validate the feature's functionality.
