-------------------------------------------
Summary: Support changing Service offering for instance with VM
Snapshots
Key: CLOUDSTACK-9539
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9539
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Reporter: Nicolas Vazquez
Assignee: Nicolas Vazquez
h3. Actual behaviour
CloudStack doesn't support changing service offering for vm instances which
have vm snapshots, they should be removed before changing service offering.
h3. Goal
Extend actual behaviour by supporting changing service offering for vms which
have vm snapshots. In that case, previously taken snapshots (if reverted)
should use previous service offering, future snapshots should use the newest.
h3. Proposed solution:
1) Adding {{service_offering_id}} column on {{vm_snapshots}} table: This way
snapshot can be reverted to original state even though service offering can be
changed for vm instance.
*NOTE:* For already created vm snapshots, {{service_offering_id}} will be null
