Scheduling policy for oVirt cluster "vm_evenly_distributed"
Hello oVirt guru`s! oVirt Engine Version: 4.0.3-1.el7.centos I test load balancing (Scheduling policy for oVirt cluster) I created a copy of the policy "vm_evenly_distributed" (see My_vm_evenly_distributed.png) The policy specified limit 2 VMs on the host. I have a 4 host in oVirt cluster. On the first host are 5 virtual machines. Other hosts do not have the VM. HOST1 - 5VM HOST2 - 0VM HOST3 - 0VM HOST4 - 0VM Now I apply the policy on a cluster and I expect that oVirt start to migrate VMs from first host to another, e.g. HOST1 - 2 VM HOST2 - 2 VM HOST3 - 1 VM HOST4 - 0 VM But in fact, migration is performed only one virtual machine: HOST1 - 4 VM HOST2 - 1 VM HOST3 - 0 VM HOST4 - 0 VM All hosts on the same hardware. VMs not have Affinity Groups. All VMs are HA-enabled and automigration-enabled What am I doing wrong?
Please provide all policy parameters(HighVmCount, SpmVmGrace and MigrationThreshold) also please specify what host is SPM. You can find some additional information how this policy works here: http://www.ovirt.org/develop/release-management/features/sla/even-vm-count-d...

Can you please show the screenshot from the clusters->edit cluster-> scheduling policy and also specify what host is SPM? On Tue, Sep 27, 2016 at 10:09 AM, <aleksey.maksimov@it-kb.ru> wrote:
