Feature Specifications

• Test guidelines
  • Functional test

• Configuration
  • There are two global configuration parameters:
    • xen.update.url - URL to get latest Xenserver Updates.
    • update.check.interval (in sec) - How frequently should CloudStack check for Xenserver Updates.
• User permission
  • Root-Admin would have privilege to list the available updates.

Use Cases

Admin can check the updates available to any host and install them manually

Admin can decide on how frequently he wants Cloudstack to check for updates and set the interval by changing the global config parameter update.check.interval .

Architecture and Design description

...

Once in a week, thread will check this location to search for updates and fill the database with available updates(if any) or admin can change the time interval to check the updates by changing the value of xen.update.check.interval global config parameter( by default interval is set to check the updates "Once in a week").

List Host Updates

http://10.102.125.207MS-SERVER:8096/client/api?command=listHostUpdates&id=&hostid=&applied=true/false

In the above mentioned API link, only hostid is required parameter and the other parameters (id and applied) are optional. If admin wants to list all the patches that are not yet applied to a host, set the applied parameter as false and if admin wants to list the applied ones, set the applied parameter as true. If applied parameter is not passed with the API, it will return the list of all applied and not applied patches. To get the details about the single patch, admin need to pass the id (uuid)* *of the patch.
