Bug 11964 - You are allowed to migrate a virtual machine on to the host that it already exists o
Changes:
Validations were missing in th MigrateVmCmd API, since from UI the validations are always done while listing hosts for migration as first step.
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.
only owner of the network can access it; if it's domain - all accounts in the domain and domain children can have an access.
* aclType replaces 2 old fields: isShared and isDomainSpecific.
* All 2.2.x account specific networks will have aclType=Account; 2.2.x Domain specific networks - aclType=domain; 2.2.x Zone level networks - aclType=Domain with domainId = Root domain id
1) if snapshot is originally created from root volume, allow only CreateTemplateCommand from snapshot 2) if snapshot is originally created from data volume, allow only CreateVolumeCommand from snapshot Reviewed by - Kishan
status 11428: resolved fixed
* can be specified for Shared network only
* if not specified for the Shared networks, try to locate it based on the zoneId and tags. If tags is not null, pick up first physicalNetwork from the zone that has matching tags. If tags is null, and there are none/more than 1 physical netwroks in the zone, error out.
