The number of instances supported by fake computes is not limited by physical
constraints. It allows you to perform stress tests on a deployment with few
resources (typically a laptop). Take care to avoid using scheduler filters
that will limit the number of instances per compute, such as ``AggregateCoreFilter``.
that will limit the number of instances per compute, such as ``NumInstancesFilter``.

Fake computes can also be used in multi hypervisor-type deployments in order to
take advantage of fake and "real" computes during tests:

Virtual disk to physical disk allocation ratio.

This option is used to influence the hosts selected by the Placement API by

configuring the allocation ratio for ``DISK_GB`` inventory.

When configured, a ratio greater than 1.0 will result in over-subscription of
the available physical disk, which can be useful for more efficiently packing
