status 11428: resolved fixed
Changes:
- VirtualMachineMgr puts the constraint that if Root volume is already READY, we provide the clusterId in the plan to the deploymentPlanner. Planner then searches for resources only under that cluster.
- If no deployment could be found, deploying VM fails.
- Fixed this, such that incase the root volume is recreatable, we call the planner again by removing the cluster constraint. Planner will then search for resources in other clusters.
- Works for system VMs(SSVM, consoleproxy, virual routers).
Changes:
- Added a new API 'migrateSystemVm' backed by MigrateSystemVMCmd.java to migrate system VMs (SSVM, consoleproxy, domain routers(router, LB, DHCP))
- This is Admin only action
- The existing API 'migratevirtualmachine' is only for user VMs

Changes:
- When management server starts, it goes through all the pending work items from op_it_work table and schedules HA work for each. It used to mark each item as done. Instead we should keep the item as pending and let it get marked as Done after the HA work is done.
- Changes in VirtualMachineMgr::advanceStop() :
a) if we find a VM with null hostId, we stop the VM only if it is forced stopped.
b) if VM state transition to Stopping fails,for state Starting and Migrating we try to find the pending work item and then do cleanup the VM. In case state is Stopping we can cleanup directly.
c) We proceed releasing all resources only if state transitioned to 'Stopping'.
- Changes in HA:
a) Depend on VirtualMachineMgr::advanceStop() in case host is not found to do VM cleanup
- When Vm state between mgmt server and agent syncs from starting -> running, mark any pending work item as done.

Changes:
1. UserVmManagerImpl :: finalizeStart()
Added null check for the cmds.getAnswers() object. Return ‘true’ if null.
2. VirtualMachineManagerImpl :: advanceStart()
Move the line to set PodId to the vm being started above the state transition where hostId gets set, so that podId is not null in case management server goes down when vm starts on the agent. On restart, podId is not updated during fullsync. So this will prevent podId remaining null.
vm.setPodId(dest.getPod().getId());
Changes:
- CreateTemplate and RegisterTemplate now support adding a template tag. It is a string value. This is root-admin only action - only admin can add template tags.
- ListTemplates will return the template tag in response.
- HostAllocator changed to use template tag along with the existing tag on service offering. If both tags are present, allocator now finds hosts satisfying both tags. If no hosts have both tags, allocation will fail.
- DB changes to add new column to vm_template table.
- DB upgrade changes for upgrade from 2.2.10 to 2.2.11
