The scheduler caches its list of available hosts. How can I view a list of available hosts created by the scheduler?

Compute uses the nova-scheduler service to determine how to dispatch compute and volume requests. For example, the nova-scheduler service determines which host a VM should launch on. The term host in the context of filters means a physical node that has a nova-compute service running on it. You can configure the scheduler through a variety of options. By default, Openstack assign instances to bare metal whose memory is larger. Below command Print a list of all aggregates giving details with Availability Zone

[root@controller~(openstack_admin)]# nova aggregate-list

Below command List all hosts by service and zone.

[root@controller~(openstack_admin)]# nova host-list

you can also check available List of hypervisors

[root@controller~(openstack_admin)]# nova hypervisor-list
