hi,
I am trying to change a behavior in vdsm. When you pass 100% load on a VM, it will stop reporting further load and will keep telling 100% until the load drops under 100% again in it's cpuIdle information. This is totally correct if you have only single-cpu VM's, but it is false when you have multiple vcpu's, I think the cpuIdle information should not be on a 0-100 scale, but on a 0-100*vcpus scale.
So I submitted this patch to vdsm: http://gerrit.ovirt.org/#/c/7892/2 and Dan pointed out that some functionality may depend on the value in the 0-100 interval. For me it seems it is ignored and the load is calculated only from sysCpu + userCpu. Does anyone build on the cpuIdle value?
Thanks, Laszlo
you are right, engine doesn't save cpuIdle for vm, so it's not in use in the engine.
Laszlo, in this case, I think it would be best to drop this bogus piece of information. Dan.
