Doron Fediuck has submitted this change and it was merged. Change subject: engine: Update Power Saving policy with power management ...................................................................... engine: Update Power Saving policy with power management Add the logic that controls the automatic power management to PowerSavingBalancePolicyUnit. The unit got two new parameters: - HostsInReserve - the amount of hosts with no VMs that should be kept running - EnableAutomaticHostPowerManagement - the feature enable flag When there are too many hosts with no VMs, the algorithm will select a host and put it first to maintenance and then down. If we need more hosts, it will start them up. http://www.ovirt.org/Features/HostPowerManagementPolicy Change-Id: I2da9f4e019c3dd006caefbaa9baf9a533ce41f3d Bug-Url: https://bugzilla.redhat.com/show_bug.cgi?id=1035238 Signed-off-by: Martin Sivak <msivak(a)redhat.com&gt; --- M backend/manager/modules/bll/src/main/java/org/ovirt/engine/core/bll/FenceVdsBaseCommand.java M backend/manager/modules/bll/src/main/java/org/ovirt/engine/core/bll/MaintenanceNumberOfVdssCommand.java M backend/manager/modules/bll/src/main/java/org/ovirt/engine/core/bll/scheduling/policyunits/PowerSavingBalancePolicyUnit.java M backend/manager/modules/common/src/main/java/org/ovirt/engine/core/common/AuditLogType.java M backend/manager/modules/common/src/main/java/org/ovirt/engine/core/common/action/FenceVdsActionParameters.java M backend/manager/modules/common/src/main/java/org/ovirt/engine/core/common/action/MaintenanceNumberOfVdssParameters.java M backend/manager/modules/common/src/main/java/org/ovirt/engine/core/common/config/ConfigValues.java M backend/manager/modules/dal/src/main/java/org/ovirt/engine/core/dal/dbbroker/auditloghandling/AuditLogDirector.java M backend/manager/modules/dal/src/main/resources/bundles/AuditLogMessages.properties A packaging/dbscripts/upgrade/03_04_0430_add_power_management_to_cluster_policy.sql M packaging/etc/engine-config/engine-config.properties 11 files changed, 324 insertions(+), 1 deletion(-) Approvals: Martin Sivák: Verified Doron Fediuck: Looks good to me, approved -- To view, visit http://gerrit.ovirt.org/22488 To unsubscribe, visit http://gerrit.ovirt.org/settings Gerrit-MessageType: merged Gerrit-Change-Id: I2da9f4e019c3dd006caefbaa9baf9a533ce41f3d Gerrit-PatchSet: 12 Gerrit-Project: ovirt-engine Gerrit-Branch: master Gerrit-Owner: Martin Sivák <msivak(a)redhat.com&gt; Gerrit-Reviewer: Adam Litke <alitke(a)redhat.com&gt; Gerrit-Reviewer: David Caro <dcaroest(a)redhat.com&gt; Gerrit-Reviewer: Doron Fediuck <dfediuck(a)redhat.com&gt; Gerrit-Reviewer: Eli Mesika <emesika(a)redhat.com&gt; Gerrit-Reviewer: Eyal Edri <eedri(a)redhat.com&gt; Gerrit-Reviewer: Gilad Chaplik <gchaplik(a)redhat.com&gt; Gerrit-Reviewer: Itamar Heim <iheim(a)redhat.com&gt; Gerrit-Reviewer: Martin Sivák <msivak(a)redhat.com&gt; Gerrit-Reviewer: Yair Zaslavsky <yzaslavs(a)redhat.com&gt; Gerrit-Reviewer: oVirt Jenkins CI Server
