12.2. Live Migration Prerequisites

Live migration is used to seamlessly move virtual machines to support a number of common maintenance tasks. It is important to ensure that your Red Hat Enterprise Virtualization environment is correctly configured to support live migration well in advance of needing to use it.
At a minimum for successful live migration of virtual machines to be possible:
In addition, for best performance, it is recommended that the storage and management networks should be split to avoid network saturation. Virtual machine migration involves transferring large amounts of data between hosts.
While each live migration event is limited to a maximum transfer speed of 30 MBps where this traffic exists on the management network it has the potential to saturate it. Having a separate logical network for storage reduces the likelihood of this issue being encountered.
