Public bug reported:

The libvirt uris allow extra parameters to be specified in the query
sting. More info here https://libvirt.org/guide/html
/Application_Development_Guide-Architecture-Remote_URIs.html

However nova interprets live_migration_uri using python string
formatting -
https://github.com/openstack/nova/blob/83256b7c789700ce837f4d136bc6ab8811f2d505/nova/virt/libvirt/driver.py#L675

This can result in a "TypeError: not enough arguments for format string"
as the query string will be url escaped (lot of % chars).
