cpu overprovisioning

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

Re: AW: cpu overprovisioning

Posted by Ugo Vasi <ug...@procne.it>.

I can confirm that stopping the machines and then making them run again 
(not with the command reboot but first stop and then start) the 
percentage reflects the correct proportion of GHz GHz allocated to 
available for moltipliati factor overprovisioning.

Thanks

AW: cpu overprovisioning

Posted by "S. Brüseke - proIO GmbH" <s....@proio.com>.

Dashboard is not wrong. You only have these resources left in your CS.

Here is an example as far as I remember:
Dashboard shows 100 GHz / 180 Ghz (cpu over provisioning is 1 / 3 Hosts each 24x 2.5Ghz)
You deploy 10 vms with 1 Ghz
Dashboard shows 110 Ghz / 180 Ghz (cpu over provisioning is 1 / 3 Hosts each 24x 2.5Ghz)
You change cpu over provisioning to 4
Dashboard shows 440 Ghz / 720 Ghz (cpu over provisioning is 4 / 3 Hosts each 24x 2.5Ghz)
You stop and start all vms
Dashboard shows 110 Ghz / 720 Ghz

Mit freundlichen Grüßen / With kind regards,

Swen Brüseke

Re: cpu overprovisioning

Posted by Bharat Kumar <bh...@citrix.com>.

Also In case of change in the overcommit value the total capacity will change instantaneously, but the used resource and the total available will change when
the capacity checker thread runs. The interval at which this will run can be changed from the global settings.

Thanks,
Bharat.

Re: cpu overprovisioning

Posted by Bharat Kumar <bh...@citrix.com>.

Hi,

The change in cpu overcommit factor will not change the amount of resource that are available to you. It will change the way you want to use the free resource available at that time. It won’t change
what was already allocated.

for example if you have deployed the VMs with overcommit say 2 and after a while you change the overcommit to 3, the used resource will be scaled based on the change.
changing the overcommit cannot create resource. It can only change the way you want to use the free resource. So now after the change in overcommit you can deploy 3 times more VMs (of
a given service offering) than usual using the the resource that is free at the time of changing the overcommit value. The perviously allocated resource cannot be freed until you
restart the VMs.

This link will tell you how resource allocation calculations are made.

Thanks,
Bharat.

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?

So after a change of cpu.overprovisioning.factor you need to reboot all

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.

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

Re: AW: cpu overprovisioning

Posted by Rafael Weingärtner <ra...@gmail.com>.

I have not looked at the code, but that seems odd.
Restarting VMs instances to update the resource usage/resource availability
when changing the overprovisioning factor.

AW: AW: cpu overprovisioning

Posted by "S. Brüseke - proIO GmbH" <s....@proio.com>.

Please try to stop and start the vm. Maybe reboot is not working here. You should start to see more free CPU after the first vm.

Mit freundlichen Grüßen / With kind regards,

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?

Re: AW: cpu overprovisioning

Posted by Ugo Vasi <ug...@procne.it>.

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?

AW: cpu overprovisioning

Posted by "S. Brüseke - proIO GmbH" <s....@proio.com>.

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

(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...

Re: cpu overprovisioning

Posted by Ugo Vasi <ug...@procne.it>.

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...

Re: cpu overprovisioning

Posted by Bharat Kumar <bh...@citrix.com>.

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.
