Re: number of cores

Eric: If you change any of memory or cpu over provisioning factors, you need to restart (from GUI or API) all running VM instances, otherwise the reported allocation/available numbers would still reflect data before your changes. If you also add/delete instances at the same time, you could

Re: number of cores

small tip - if you change cpu overprovisioning on CLUSTER level, no need to restart management server - it's applied immediately on the fly. On Tue, 20 Nov 2018 at 00:59, Eric Lee Green wrote: > On 11/19/18 3:47 PM, Yiping Zhang wrote: > > Eric: > > > > What's your value for global setting

FYI, tested again (CPU overprovisioning factor=1 on both Cluster and Global level - so NO overprovisioning) deployed VM unti it failed (could not deploy any more): At moment of failure: cpu used 79% (90% is disabled threshold, but VMs is big one, so would cause 91-92% usage) number of cpu cores:

Hi Dag, Firts of all, thank you very much for your response. The procedure that I carried out is described in the following link: http://docs.cloudstack.apache.org/projects/archived-cloudstack-getting-started/en/4.3/networking/autoscale_without_netscaler.html This instructions are written

Re: number of cores

Eric, I sent you numbers from KVM, Ubuntu 14.04 (qemu/libvrti from Ubuntu 16.04) Can you please reproduce the issue and upload logs - make sure to truncate logs prior to clicking the "FINISH" button in the VM creation wizard.. Upload to pastebin, so we can check it Cheers On Mon, 19 Nov 2018 at

RE: number of cores

I am with KVM. I am sure it’s the core count preventing me from starting VM’s because when I hack the database to tell it I have 48 cores rather than 24 cores on my hosts, I can then start the VM. The only thing the logs say is that I can’t create a new VM due to lack of resources. Then it

Re: KVM NFS template image

Developers please correct me... but as far as I remember there is a garbage collector which does remove the templates from primary storage once they are not needed (i.e. have no more "child VMs"). This is controlled by the global setting "storage.template.cleanup.enabled". Regards, Dag

Andrija - not sure about your 3.4GHz cores - must a be a simplified lookup somewhere making assumptions. Eric - have just tried your scenario in my 4.11.2RC5 lab (admittedly with VMware, not KVM) - and I can see my core allocation keeps going up, e.g. at the moment it sits at 166% - 10 out of

Thx Dag for confirmation. Speaking about CPU cores - I do have one "problem" which not sure is possible to solve in meaningful way 2 x 8 core Intel Xeon E5 2.6GHz nominally (with HT enabled), with burst to 3.4 GHz ( but ! only a few cores can burst to that 3.4 - not all at the same time !) -

Re: number of cores

Ultimately there will always be a 1-to-1 relationship between vCPU cores and physical cores - you can't make a 4vCPU VM run on an "overprovisioned 2 physical core" hypervisor (unless you consider Intel HT to be exactly this). You can only overprovision time slices of your total clock cycles. If

Unless someone gives you better answer, I guess it's for fun - to have more detailed numbers in dashboard (may be it's related to other hypervisor types, just assuming... or not...) Cheers On Mon, 19 Nov 2018 at 14:11, Ugo Vasi wrote: > Hi Andrija, > not having noticed this new voice before I

Re: number of cores

Hi Andrija, not having noticed this new voice before I wondered if it is limiting the fact of reaching or exceeding the number of physical cores. What is the purpose of this dashboard pane? Il 19/11/18 12:56, Andrija Panic ha scritto: Hi Ugo, Why would you want to do this, just curious ?

Hi all, in the dashboard of an ACS installation vesion 4.11.1.0 (Ubuntu 16.04 with KVM hypervisor), the new entry "# of CPU Cores" appears. Is it possible to over-provision like for MHz or storage? Thanks -- *Ugo Vasi* / System Administrator ugo.v...@procne.it
