Subject: [Users] Query on Load balancing policies.
Hi,
I have been trying out various cluster policies on latest ovirt.
On enabling Load Balancing policy: power saving, I have observed
migration of VMs and consolidating them on fewer hosts resulting in
under utilised hosts cleared of VMs.
Is the onus on the administrator to switch off all
under utilized systems ? Is there any knob I am missing
that automatically turns off under utilized hosts
and powers on the hosts on a need basis.
Regards,
Deepthi
Hi Deepthi,
The general answer would be yes; the admin should suspend / turn off
the servers and then back on as needed. Some servers will automatically
lower power consumption when working on low load using acpi profiles such
as "ondemand". So be design you can save power without actually turn
off / suspend the servers.
We're currently working on improving our scheduling sub-system, so once
we have it in place we'll start looking into RFEs such as this one.
Patches are always welcome ;)
