Host Aggregates

Overview

Navigate to Compute > Host Aggregates (admin view). The page has two tabs: Host Aggregate (manage groups) and Availability Zones (read-only zone list).

Create a Host Aggregate

Click Create Host Aggregate. The modal form includes:

Field	Type	Required	Description
Name	Text	Yes	Aggregate name
Create New AZ	Radio (Yes/No)	Yes	Whether to create a new availability zone
Availability Zone	Dropdown	If not creating new	Select existing zone
New AZ Name	Text	If creating new	Name for the new zone

Manage Aggregates

Action	Location	Description

Manage Host	More dropdown	Add/remove compute hosts (multi-select table showing Host, Zone, Status, State)
Manage Metadata	More dropdown	Set key-value metadata for scheduler matching

Availability Zones

The Availability Zones tab shows a read-only list of all configured zones. Zones are created through host aggregates — assign an aggregate to a zone name to define a new availability zone.
