vMotion is a feature of VMware vSphere that enables live migration of virtual machines (VMs) from one physical server to another without any downtime. This is possible because VMs are abstracted from the underlying hardware and can be moved between hosts without any interruption to their operation or impact on user experience.
To configure vMotion in vSphere, follow these steps:
1. Verify that your VMware environment meets the requirements for using vMotion. This includes having shared storage between hosts and compatible CPUs.
2. Configure a vMotion network on each host in your vSphere cluster. This is a dedicated network that is used exclusively for vMotion traffic.
3. Enable vMotion on each host, which involves selecting a vMotion network and configuring other migration settings, such as maximum concurrent vMotions.
4. To perform a vMotion, right-click on the VM you wish to migrate and select “Migrate”. Follow the prompts to select the destination host and storage, and choose “Change both host and storage”.
5. VMware vSphere will then automatically move the VM to the target host without interrupting the application or user experience.
Overall, vMotion provides administrators with greater flexibility in managing and optimizing their virtualized workloads, reducing downtime and enhancing performance without any negative impacts on the user experience.
