Subject [jira] [Created] (CLOUDSTACK-492) Document procedure to choose default System Offering for System VMs
Date Thu, 15 Nov 2012 18:58:12 GMT
Kirk Kosinski created CLOUDSTACK-492:

             Summary: Document procedure to choose default System Offering for System VMs
                 Key: CLOUDSTACK-492
             Project: CloudStack
          Issue Type: New Feature
          Components: Doc
    Affects Versions: 4.0.0
            Reporter: Kirk Kosinski
            Priority: Minor

While it is possible to manully change the System Offering for a particular System VM, a CloudStack
administrator may want to change the System Offering used by default for System VMs. It would
be useful for this procedure to be documented. The following procedure works for me on CloudStack
3.0.2 and 4.0.0-incubating.

1. Create a new system offering with the desired settings. This can be done via UI under the
Service Offerings tab. 
2. Back up the database. 
mysqldump -u root -p cloud | bzip2 > cloud_backup.sql.bz2 
3. Open a mysql prompt to be able to run queries in later steps on the cloud database.
mysql -u cloud -p cloud
4. In the disk_offering table in the database, identify the original default offering and
the new offering you wish to be used by default. Make a note of their id. 
select id,name,unique_name,type from disk_offering; 
5. Set unique_name = NULL for the original default offering. It is important to use the correct
value for id. 
update disk_offering set unique_name = NULL where id = 10; 
6. For the new offering you wish to be used by default, set unique_name = ''
(for the default CPVM offering) or '' (for the default SSVM offering).

update disk_offering set unique_name = '' where id = 16; 
7. Restart CloudStack. This is required because the default offerings are loaded into memory
at start-up. 
service cloud-management restart 
8. Destroy the existing CPVM or SSVM and wait for it to be recreated. The new CPVM or SSVM
will be configured with the new offering. 

Note that CLOUDSTACK-338 seems to be requesting that the string used in unique_name be change.
When that happens, this procedure would need to be updated with the correct string.
