The Live Migration process is performed in the following steps:
-
An administrator initiates a Live Migration between the source and target cluster node.
A duplicate virtual machine is created on the target cluster node, as illustrated in the following figure.
Figure 10: Creation of target virtual machine on target cluster node
All of the current memory in the source virtual machine is copied to the target virtual machine, as illustrated in the previous figure.
Clients connected to the source virtual machine continue to run on the source virtual machine and create mirrored memory pages as illustrated in the following figure.
The mirrored memory pages are tracked and continue an iterative copy of the dirty memory pages until all memory pages are copied to the target virtual machine, as illustrated in the following figure.
Figure 11: Iterative copy of mirrored memory from source to target virtual machine
When all memory pages are copied to the target virtual machine, clients are automatically redirected to the target virtual machine and the source virtual machine is deleted, as illustrated in the following figure.
