#. **Live migration completion timeout**

instance's memory size in GiB. In the case of block migration, the size of
ephemeral storage in GiB is added.

config option. The timeout is calculated based on the instance size, which
is the instance's memory size in GiB. In the case of block migration, the
size of ephemeral storage in GiB is added.
The timeout in seconds is the instance size multiplied by the configurable
parameter :oslo.config:option:`libvirt.live_migration_completion_timeout`,
