Update the Windows Azure Guest OS from the Management Portal
Updated: September 27, 2013
You can configure the update mode of a service that contains web roles or worker roles by using either the Windows Azure Management Portal or by updating the service configuration file.
When you deploy a cloud service (formerly called a hosted service) in Windows Azure, the default behavior is to install the most recent operating system version, and to configure the service deployment for automatic guest OS updates. If you specify a specific Guest OS version, you will have to initiate each Guest OS update manually using the Management Portal or by modifying the service configuration file.
|The osFamily and the osVersion attributes have no effect on the update mode of a VM role or a Windows Azure Virtual Machine.|
To update the Windows Azure Guest OS for a cloud service
Log into the Windows Azure Management Portal.
On the left pane choose Cloud Service, then choose the name of the service you want to modify.
Choose Staging or Production as appropriate. You need to configure each deployment independently.
At the bottom of the page, find the operating system section.
The version of the Guest OS you are running for this Cloud Service is identified by the OS FAMILY and OS VERSION drop downs. A value of Automatic means that you are running the latest version of the chosen OS FAMILY. A value of Retired OS or something similar means you are manually configured to use an older version of the Guest OS that is no longer supported. Consult the Windows Azure Guest OS Releases and SDK Compatibility Matrix for the policy on retired Guest OS versions. If you do not take action at some point, your service will be force upgraded to a later Guest OS.
In OS FAMILY, select the operating system family you want to run.
In OS VERSION, select the version of the Guest OS you want to run. Set this value to Automatic to receive the latest Guest OS release for that operating system family as it becomes available. Setting it to any other value fixes that deployment to use only that version of the Guest OS. You will need to manually reset this value in the future in order to update the Guest OS.
