vSphere 8 vMotion Improvements

vSphere 8 was announced at VMware Explore 2022 in San Francisco. Part of this new major release are vMotion updates. vMotion is extensively developed to support new workloads and is one of the key enablers for VMware’s multi-cloud approach. Whenever a workload is live-migrated between vSphere and/or VMware Cloud infrastructures, vMotion logic is involved.

With the release of vSphere 7, the vMotion logic was updated to greatly reduce the performance impact on applications during live migrations. Significant work was done to minimize the stun-time, aka the switch-over time, where the last memory pages and checkpoint info are transferred from source to destination. (more…)

vMotion Enhancements in vSphere 7

–originally authored and posted by me at https://blogs.vmware.com/vsphere/2020/03/how-is-virtual-memory-translated-to-physical-memory.html–

The vSphere vMotion feature enables customers to live-migrate workloads from source to destination ESXi hosts. Over time, we have developed vMotion to support new technologies. The vSphere 7 release is no exception to that, as we greatly improved the vMotion feature. The vMotion enhancements in vSphere 7 include a reduced performance impact during the live migration and a reduced stun time. This blog post will go into detail on how the vMotion improvements help customers to be comfortable using vMotion for large workloads.

To understand what we improved for vMotion in vSphere 7, it is imperative to understand the vMotion internals. Read the vMotion Process Under the Hood to learn more about the vMotion process itself. (more…)

The vMotion Process Under the Hood

The VMware vSphere vMotion feature is one of the most important capabilities in today’s virtual infrastructures. Since its inception in 2002 and the release in 2003, it allows us to migrate the active state of a virtual machines from one physical ESXi host to another. Today, the ability to seamlessly migrate virtual machines is an integral part of nearly every virtualization deployment. The portability of workloads is the foundation for true hybrid cloud experience by being able to move them between on-premises and public clouds using VMware Hybrid Cloud Extension (HCX). vSphere vMotion still is and always will be one of the most momentous game-changers in the IT industry.

A lot has been developed on the vMotion internals over the years to support new technologies.

vSphere 6: vMotion enhancements

Don’t we all remember when we witnessed our first vMotion and realized which awesome things this made possible in virtualization?!  In vSphere 6 vMotion even got better!

vMotion version history

First I’d like to give a short overview about what was already achieved in previous versions of vSphere.

vSphere 5.0:

  • Multi-NIC vMotion
    Migration time reduced by making Multi-NIC vMotion possible.
  • Stun During Page Send
    Stunned source machine if needed to progress pre-copy phase of vMotion, so the memory modification rate stays below the precopy transfer rate and the pre-copy will eventually succeed.

vSphere 5.1

  • vMotion without shared storage
    Allows for moving the VM simultaneously to another computing & storage resource at the same time.
