1. able to restore VM from its original template
2. Only allow to restore when VM is running or stopped
3. after restoring, VM state will not change, e.g. running is still running
status 9949: 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
1) Introduce new managers - ProjectManager and DomainManager. Moved all domain related code from AccountManager to DomainManager.
2) Moved some code from ManagementServerImpl to the correct managers.
3) New resource limit for Domain - Project

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:
To make sure migration does not attempt to pick a host that has running VMs more than the max guest VM's limit:
- Changed manual migration to call host allocators to return a list of hosts suitable for migration. Host allocators check for the max guest VM limit.
- Earlier we returned hosts with enough capacity but now Host Allocators make other checks along with capacity. So the list of hosts returned are hosts that have enough capacity AND satisfy all other conditions like host tags, max guests limit etc. Or in other words Allocators dont return the hosts that dont satisfy all conditions even if they have capacity.
-Therefore, now we mark the list of hosts returned for manual migration as 'suitable' hosts instead of 'hasenoughCapacity' in the HostResponse.
- HA migration already calls allocators, so no change is needed there.
Changes:
- Adding a new table 'hypervisor_capabilities' that will record capabilities for each hypervisor version. Added db schema changes for this.
- Currently a few capabilities have been added, namely, 'max_guests_limit' and 'security_group_enabled'
- Added a new column 'hypervisor_version' to host table. StartupRouting command now takes in this parameter. It should be set when a host connects.
- If a host's hypervisor version is not present, we find all the capabilities rows for that hypervisor type and use the first record.
- 'max_guests_limit' is the maximum number of running guest Vms that a host can have for the given hypervisor.
- Host Allocators use this limit and skip a host if the number of running VMs on that host exceeds this limit.
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
