Now we are going to |IsolatedHostsFilter|. There can be some special hosts
reserved for specific images. These hosts are called **isolated**. So the
images to run on the isolated hosts are also called isolated. The filter
checks if ``image_isolated`` flag named in instance specifications is the same
as the host. Isolated hosts can run non isolated images if the flag
``restrict_isolated_hosts_to_isolated_images`` is set to false.

|DifferentHostFilter| - method ``host_passes`` returns ``True`` if the host to
place an instance on is different from all the hosts used by a set of instances.
