vMotion is a VMware feature that allows users to transfer multiple virtual machines between different hardware and storage systems, regardless of their operating system. It also provides an audit trail and takes only a few seconds to complete, making it a powerful tool for virtual machine migration.
FAQ: Migrating Virtual Machines with vMotion
WHAT is vMotion?
vMotion is a feature of VMware’s vSphere virtualization software that allows users to migrate virtual machines from one physical host to another without any downtime. This can be done across any sort of supported hardware and storage using vMotion, which also provides an audit trail. This feature is designed to support the movement of virtual machines for maintenance, load balancing, disaster recovery, and other purposes.
How does vMotion work?
vMotion allows virtual machines to move between different physical hosts. vSphere is able to achieve this through shared storage, which is the storage system that appears as a locally attached disk to all physical hosts. Shared storage enables physical hosts to access the virtual machine’s disk files, regardless of the physical location of that host. When a virtual machine is moved from one host to another with vMotion, the virtual machine’s memory and execution state are transferred to the destination host.
What are the benefits of vMotion?
vMotion provides many benefits to users of virtualization technology. Some of the main benefits include:
- Zero downtime: vMotion allows virtual machines to be live migrated from one host to another with little or no downtime or disruption to the end user.
- Maintenance: Administrators can use vMotion to move virtual machines from hosts that need maintenance to hosts that do not, without requiring any downtime for the virtual machine.
- Load balancing: vMotion allows virtual machines to be moved from hosts that are overloaded to hosts with available resources, improving performance and reducing the risk of downtime.
- Disaster recovery: vMotion enables virtual machines to be moved to a different data center or location, reducing the risk of data loss and ensuring business continuity.
vMotion is a powerful feature of VMware’s vSphere virtualization software that enables users to migrate virtual machines from one physical host to another without incurring any downtime. This feature provides many benefits to users, including improved performance, reduced risk of downtime, and enhanced disaster recovery capabilities. By leveraging vMotion, virtualization administrators can ensure maximum uptime for their virtual machines and achieve a high level of flexibility for their infrastructure.
