[ovirt-users] Power Saving Schedule

2022-05-19 Thread Maton, Brett
Hi List,

  I'm using the power_saving schedule to minimise the number of physical
hosts which works as expected when scaling in, however it doesn't appear to
ever scale out.

  I've tried setting the minimum and maximum RAM and lowering the HighUsage
(Utilization in American) percentage but it never starts another host.

  If I don't change the scheduling policy and manually start another host,
it gets powered off by the scheduler before any resources get allocated to
it.

  Am I missing a setting or is it just a MASSIVE flaw in the scheduler?

[ovirt-users] Power Saving schedule, hosts not shutting down

2021-10-28 Thread Maton, Brett
Hosts still not shutting down,  VM's get moved from host to host by
Migration initiated by system (reason load balancing)
events every few hours, unfortunately there is nothing in the event logs
about power management though.

Any thoughts or suggestions on logs to look into?

Regards,
Brett

[ovirt-users] Power Saving schedule, hosts not shutting down

2021-10-19 Thread Maton, Brett
Hi,

  I'm having trouble with the power_saving Scheduling Policy not shutting
down idle hosts

  Policy is more or less default, I added 'HostsInReserve 0' too see if
that would help, and then  24hrs later I bumped
CpuOverCommitDurationMinutes to 15 that didn't make a difference either.
(not unexpected as the CPU is only being tickled by two small VMs at the
moment).

  3x Dell Hosts with iDRAC 8 management cards, power management configured
and functional.
  oVrit 4.4.8.6-1.el8

Thanks in advance for any help

Brett
