Subject: [ovirt-devel] [Localization Question] Cluster Policy "power_saving"

Hi oVirt developers, =


I am currently translating documentation and I would like to ask you one qu=
estion on power_saving Cluster Policy, =

in order to understand the mechanism properly so that I can translate accur=
ately. =

(Please excuse me -- this might be a basic concept, but it is a bit confusi=
ng for me) =


My understanding is that when this is selected, the Manager tries to shut d=
own a host which has the lowest usage within the cluster (so that it can sa=
ve the power). =

In order to shut it down, VMs running on that host need to be migrated to o=
ther host. =

Which host will be the destination? =

Would it be the host with the second lowest usage rate? =


Many thanks in advance, =


Yuko Katabami =
