Can someone explain the cluster policies to me? The explanation at
http://www.ovirt.org/Features/Even_VM_Count_Distribution is not quite clicking for me.
* HighVMSCount - Maximum VM limit. Exceeding it qualifies the host as overloaded. (
Understood )
* MigrationThreshold - defines a buffer before we start migrating VMs from the host (
Not quite grasping. If my High limit is 5 does this mean that it will only begin to move
VMs when the count reaches 10? )
* SPMVMCountGrace - defines how many slots for VMs should be reserved on SPM hosts
(the SPM host should have less load than others, so this variable defines how many VM less
it should have) ( Does this mean that if I have a host with only 3 VMs the SPM will 3 VMs
minus the SpmWmGrace? Or is this HighVmCount minus SpmVmGrace count?)
