#. **Live migration completion timeout**

instance's memory size in GiB. In the case of block migration, the size of

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`,
