Change the compute resource of a VM while it is online (Change compute resource only) Let’s take a walk through of the different types of vMotion using this as our basis. If you right click a Virtual Machine in vCenter, you will see the above options. Today, when you migrate a virtual machine, you have many more options than you did when vMotion made its debut in 2003. Since virtual machines can stick around for a long time, features like vMotion and Storage vMotion make it easy to migrate virtual machines between hosts, clusters, storage arrays, etc. For example, you can move a virtual machine to a new datastore to migrate off an old storage array, or to a datastore with faster disks if you need better performance. There are a couple of cases where this feature is extremely handy, as mentioned in VMware’s Storage vMotion documentation. It allows you to move the virtual machine’s files between datastores while a virtual machine is running. While vMotion focuses on the state of the virtual machine, Storage vMotion is all about, well, the storage. We will talk more about vMotion requirements soon. Remember, this is a classic vMotion, so two important required components are shared storage and shared networking. Once the state has been transferred, the virtual machine will be running on ESXi Host 2, the destination. As part of the vMotion operation, which moves the virtual machine from ESXi Host 1 to ESXi Host 2, we are transferring all of the information about our virtual machine between the ESXi hosts, including the contents of the virtual machine’s memory. On ESXi Host 1, we have our virtual machine in its origin. We are transferring everything that makes our virtual machine our virtual machine! Take a look at this diagram:

This information includes BIOS, devices, CPU, MAC addresses for the Ethernet cards, chip set states, registers, and so forth.
According to VMware’s vSphere 6.7 vMotion Documentation, this is: The state of the virtual machine is the contents of memory (what the virtual machine is actively doing), and the information on the virtual machine that makes it unique. When you read about vMotion, you will read about the state of the virtual machine. VMotion works by transferring the virtual machine from one host to another without any disruption to the virtual machine or applications it is serving. VMotion did have some requirements that we are all familiarly with still today, such as shared storage, shared networking, and a network to use for the transfer of the virtual machine state. You will also notice vMotion used to be stylized with a big v, as VMotion. Be sure to check out the section on Migrating Virtual Machines in the Virtual Center 1.0 Documentation. vMotion is one of those things that has been constantly enhanced with new vCenter and ESXi releases through the year.Īs a history lesson, VMware vMotion first debuted in Virtual Center 1.0. For example, I can move a virtual machine from one ESXi host to a different ESXi host and my users will not notice. It allows a virtual machine to change where it is running without any downtime.
