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 :
- Login to Cloudmin and go to Host Systems -> Location Groups.
- In the first empty row check the box in the Active column.
- Enter a name for the group in the Description column.
- 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.
- Click the Save button.
Once a group has been created, you can assign a host system to it as follows :
- Open the Host Systems category on the list menu and click on the link for your host system type, such as Xen.
- Click on the host you want to assign.
- 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.
