Nicolas Vazquez updated CLOUDSTACK-9539:
----------------------------------------
Description:
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: Existing vm snapshots are populated on update script by {{UPDATE
vm_snapshots s JOIN vm_instance v ON v.id = s.vm_id SET s.service_offering_id =
v.service_offering_id;}}
