- fixed bug in the destroying the VPX instance on SDX
- added method to acuire priavate IP from the zone, needed for the management IP of provisioned LB appliane
Changes:
- Added a two new deployment planners 'UserDispersingPlanner' and 'UserConcentratedPodPlanner' to the DeploymentPlanners
- Planner can be chosen by setting the global config variable 'vm.allocation.algorithm' to either of the following values:
('random', 'firstfit', 'userdispersing', 'userconcentratedpod')
- By default, the value is 'random'. When the value is 'random', FirstFitPlanner is invoked as before that shuffles the resource lists.
- Now Admin can choose whether the deployment heuristic should be applied starting at cluster or pod level. This can be done by using the
global config variable 'apply.allocation.algorithm.to.pods' which is false by default. Thus by default as earlier, planner starts at clusters directly.
'UserConcentratedPodPlanner' changes:
- Earlier to 3.0, FirstFitPlanner used to reorder the clusters in case this heuristic was chosen.
- Now this is done by a separate planner and is applied only when 'vm.allocation.algorithm' is set to this planner
- It reorders the capacity based clusters/pods such that those pods having more number of Running Vms for the given account are tried first.
- Note that this userconcentration is applied only to pods and clusters. Not to hosts or storagepools within a cluster.
'UserDispersingPlanner' changes:
- 'UserDispersingPlanner' reorders the capacity ordered pods and clusters based on number of 'Running' VMs for the given account in ascending order. Aim is to choose thodes pods/clusters first which have less number of Running VMs for the given account
- Admin can provide weights to capacity and user dispersion so that both parameters get considered in reordering the pods/clusters. This can be done by setting
the global config parameter 'vm.user.dispersion.weight'. Default value is 1. Thus if this planner is chosen, by default, ordering will be done only by number of Running Vms, unless the weight is changed.
- HostAlllocators and StoragePoolAllocators also reorder the hosts and pools by ascending order of number of Running VMS/ Ready Volumes respectively for the given account. Thus try to choose that host or pool within a cluster with less number of VMs for the account.
TODO:
- Still leaving the provider columns in data_center schema as-is for CloudKit and BareMetal
- ExternalNetworkDeviceMgrImpl still needs to fix the dataCenter.setProviders calls and externalNetworkApplicance usage checks to see if zone has external networking.
- Create Zone changes and changes to data_center table to remove vlan, securityGroup fields
- Physical Network lifecycle APIs
- Physical Network Service Provider APIs
- DB schema changes
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
The step to upgrade xenserver,
1. put cluster in Unmanaged state through UI , then MS will not talk to hosts in the cluster
2. upgrade xenserver according to XenServer upgrade guide.
3. put cluster in Managed state through UI, then MS will reconnect hosts
TODO,
1. UI
2. vm pool sync , leveraged from kelven's work
- CreateZone API creates a zoneToken, inserts in DB and returns it in the
response
- UpdateZone API takes in 'details' map that is loaded to data_center_details
Changes:
- Cluster entry is not removed from the table when a cluster is deleted because there are some foreign key constraints failing if the row delete is attempted. Instead the cluster is marked as 'removed'
- While deleting the pod changed the check to see if pod has any clusters - we now check that there are no clusters with removed column null.
- Also pod entry cannot be deleted from the db due to foreign key constraints. So added 'removed' column to Pod table host_pod_ref
- Now on deleting a pod, the pod will be marked as removed and pod name is set to null.
