Hi,
I would like to see a more advanced type of Power-Saving Cluster policy,
where an empty Host gets put into a sleep-mode, so that it draws as
little power as possible and can be awoken by engine when VM's starts to
use more resources.
A typical scenario would be that all VM's are spread evenly over Hosts
during day-time, when customers are actively using their VM's. But then
during off-hours, VM's gets clumped up into maybe one or two Hosts, and
the other Hosts can be put to sleep to save energy, and then woken up in
the morning again.
I agree. Current power-saving policy doesn't do much other than
consolidating VMs. Having a tunable based on which X/Y idle hosts in the
cluster could be powered-off, where Y-X hosts are ON just for backup. I
would love to see that in the coming days in oVirt.
It would also benefit if there is some kind of power-metering that is
flagged in the GUI. How much power each system is consuming and over-all
cluster is consuming.
This would be a real handy number to access power consumption of the
systems.
