Change subject: upgrade from 3.0.7 to SI24.4 fail(#879918) ...................................................................... upgrade from 3.0.7 to SI24.4 fail(#879918) upgrade from 3.0.7 to SI24.4 fails: ERROR: insert or update on table vm_device violates foreign key constraint fk_vm_device_vm _static This bug is a result of missing FK between vmt_guid in vm_interface and vm_guid in vm_static. This cause junk interface left in vm_interface when a template that has interfaces is removed. Since in upgrade from 3.0 to 3.1 we added the vm_device table, there is an attempt to insert those junk interfaces to vm_device that fails on the FK constraint between vm_device and vm_static. This patch fix the bug by: 1) Fixing the upgrade script to cleanup those junk interfaces before an attempt to insert it to vm_device is done. 2) Adds the missing FK between vm_interface and vm_static to prevent junk data in future.
