Hi Swen,
I try rebboting 2 vm but the amount of cpu MHz is not changed. Do I have
to restart all vm before you see a change?

This is because the factor of overprovisioning is attached to the instance too!
And this factor is only changing after rebooting the instance.
So after a change of cpu.overprovisioning.factor you need to reboot all
instances on this cluster which were running before this change was made.
Mit freundlichen Grüßen / With kind regards,
Swen Brüseke

Betreff: Re: cpu overprovisioning
If I change the over-provisioning ratio in cluster-relative settings
(infrastructure->cluser->cluster-name->settings) the dashboard show the sum of
real GHz the overprovisioned amount of GHz (324GHz) as aspected, but after a while also
the sum of Ghz is multiplied by the same factor making it unnecessary...

In case of cloudstack, cpu capacity for host is total of cpus * no of Ghz *
overporvisoning.
total capacity = sum of capacities of individual hosts.
Thanks,
Bharat.

Available CPU will be 3 times the actual CPU when over provisioned by 3.
The UI not showing the over provisioned value seems like a bug.

Hi all,
we have a cluster of three machines with 16 CPU at 2.2GHz each and we have set
a cpu-overprovizioning to 3.
I would expect that the CPU system capacity of the dashboard appear with the
sum of megahertz CPUs multiplied by three instead I get the real sum (108MHz).
I do not understand if this overprovisioning allows me to allocate more MHz of
real ones asthe documentation say since in reality the virtual machines occupy
on average only 20% of the computing power.
thanks in advance
