Re: CPU Overprovisioning
Assuming you are on KVM...total number of Shares = total number of Mhz (cores * Mhz) / cpuOverprovisioningFactor - cpu shares get changed (after changing cpu overprovisioning) only when you stop and start an existing VM. So i.e. 2 vCPU of 2000 MHz VM, with CPU overprovisioning of 2 will get (2*2000)/2= 2000 CPU shares In that regards, there are no "reservation" specifically, but cpu shares are "engaged" only when there is shortage of CPU cycles on the host, otherwise is not applicable. CPU cap has been implemented for KVM only in 4.12 (if not mistaken), but in general even if CPU cap has been set on the offerings, if changing cpu overprovisioning factor, cpu cap will NOT change on hypervisor side (can confirm for XS and VMware but expect same for KVM in 4.12) - i.e. it always stays the same. Hope that helps, Andrija On Sun, Jul 7, 2019, 18:04 Fariborz Navidan wrote: > Hello, > > How VMs receive CPU shares when cpu over provisioning factor is increased > and CPU cap is disabled for them? > > Thanks >
CPU Overprovisioning
Hello, How VMs receive CPU shares when cpu over provisioning factor is increased and CPU cap is disabled for them? Thanks
Re: Cpu Overprovisioning factor
No (currently). Perhaps in next year or so, we *might* have some changes around that, but atm - no.

Cpu Overprovisioning factor
Hello All, Is there any way to force ACS to take into consideration the new cpu overprovision factor without having to shoutdown lots of VMs on the host? Thanks

Re: cpu overprovisioning
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. https://cwiki.apache.org/confluence/display/CLOUDSTACK/CPU+and+RAM+Overcommit Thanks, Bharat.

KVM CPU Overprovisioning issues.
I'm trying to figure out how CPU over-provisioning works in
cloudstack. It seems that no matter how much I change the
over-provisioning factor value in global settings, I cannot
over-provision CPU allocation on the hosts. I suspect that I'm just
having a lack of understanding on my part, but it seems like I should
be able to increase the number of VMs I can deploy by increasing the
CPU over-provisioning value (given that I'm not close to any other
resource limits). But this doesn't seem to be the case in practice.

Re: KVM CPU Overprovisioning issues.
If not mistaken, there is global overprovisioning factor, and there is
cluster level overprovisioning - the last one takes presedence I think...

Re: KVM CPU Overprovisioning issues.
When the deployment goes through, the allocation placement algorithm
will tell you if cpu over provisioning worked. You can see it in
management-server.log file..
Here is an easy way to extract useful info for failed vm deployment.
After deployment failed, grep for cloudstack internal name of the VM and
note the job id (i see in your log it was job-7312) in
management-server.log . Once you have the job id, grep 'job-'
management-server.log. Post the content here... I do see you post it the
log below, it appears we are missing some info.
You can override CPU overprovisioning values in global settings as well
as cluster settings.
If you are enable CPU reservations, than it probably wont work, because
you trying to reserve more than whats available.
What version of ACS you have and what hypervisor?

Re: Cloudstack 4.3 KVM CPU overprovisioning
I've found more information on the host I have 2 sockets Processor Information Socket Designation: CPU1 Type: Central Processor Family: Xeon Manufacturer: Intel Processor Information Socket Designation: CPU2 Type: Central Processor Family: Xeon According to /proc/cpuinfo I have 24 cpu's processor : 23 vendor_id : GenuineIntel cpu family : 6 model : 44 model name : Intel(R) Xeon(R) CPU X5660 @ 2.80GHz According to Cloudstack cpu count matches *Total CPU24 x 2.79 GHz**CPU Allocated for VMs97%* But *The Number of CPU Sockets1* On KVM counting vcpus and matching that one to the real CPU;s #of VCPUS living in - Physical CPU Number 4 - 0 1 - 1 2 - 2 2 - 3 1 - 4 6 - 5 2 - 6 1 - 10 6 - 12 5 - 14 1 - 17 1 - 22 For example 4 vcpus are living in CPU 0 so overprovisioning is working, now why is it that cloudstack sees this host as 97 % full when I'm using only *12 CPU's* Where are the rest of my CPU's Any help would be really appreciate it Cheers On Tue, Jun 17, 2014 at 5:11 PM, Prashant Kumar Mishra prashantkumar.mis...@citrix.com wrote: I am giving an example based on my understanding.

Cloudstack 4.3 KVM CPU overprovisioning
Dear Cloudstack users, Our current setup is using dell blades with 24 cpus on KVM, currently we have 5 servers like that(120 cpus) , and 28 Vm's currently running all of them linux centos with virtio modules the majority of the vm's have 2 vcpus per VM so that would be around 56 vcpus According to my Cloudstach Dashboard I'm already in 56 % usage of CPU's, it seems that CPU overprovision is not working on KVM, I've setup cloudstack in global preferences to have a 100 guests per hosts as the limit if I my understanding is correct then I should be able to provision around 500 vms on those 120 cpu's if I wanted to using cpu overprovision. How can I confirm if CPU overprovision is working as far as I can see cloudstack is detecting the right numper of cpu's per physical host Total CPU24 x 2.79 GHzCPU Utilized3.9%CPU Allocated for VMs97%Memory Total126.02 GBMemory Allocated53.50 GBMemory Used36.74 MBNetwork Read35.99 GBNetwork Write Any help would be really appreciate it thanks
CPU overprovisioning.
Hi all, I configured CPU over provisioning factor 2.0 but cloudstack (4.2) shows no changes on the dashboard. computational nodes are XenServer 6.2, 2x4cores. Any hints are more then welcome. Dan. This message was sent using IMP, the Internet Messaging Program.
Re: CPU overprovisioning.
Did you restart the management service after making the change?

Re: CPU overprovisioning.
Did you change the global setting or the cluster setting ? In 4.2 changing global setting only affects the newly created clusters factor not the existing ones.

That is what i didn't know about. Is it possible to update that settings for existing cluster ? Did you change the global setting or the cluster setting ?
