Location Groups

Introduction to Location Groups

A location group contains a set of host systems, typically in the same physical location. When a virtual system is created you can select a location group instead of a specific host, and Cloudmin will choose a host from that group based on some selection method. The selection may be random, or based on free memory or disk space.

Location groups are most useful when you have a large number of host systems in different locations, and want to avoid selecting an appropriate one manually for each new virtual system. It is quite possible to have just a single location group if all your host systems are in the same datacenter and treated equally for allocation purposes.

Creating a Location Group

To add a new location group, do the following :

  1. Login to Cloudmin and go to Host Systems -> Location Groups.
  2. In the first empty row check the box in the Active column.
  3. Enter a name for the group in the Description column.
  4. Select an allocation method from the Host selection method column. We recommend Most free RAM, as that is the resource likely to run out first.
  5. Click the Save button.

Once a group has been created, you can assign a host system to it as follows :

  1. Open the Host Systems category on the list menu and click on the link for your host system type, such as Xen.
  2. Click on the host you want to assign.
  3. Select the group from the Location group menu, then click Save.

Once at least one running host system is in a group, you will be able to select it on the Create System page.
