Hi Steffen and Ruben, Thank you for the feedback, regarding the topics:
What DB are you using ? SQLite or MySQL ? > We are using SQLite. I will try some queries directly on DB, but I agree with you and Ruben that it would be a surprise if they took 140s. 1.- Prolog Times constant means that your are not suffering an storage > problem > I agree, without storage problems, neither network problems (due to tm_ssh transfer driver). > 2.- Pending Times increasing. This depends on the number of VMs to > schedule, and the number of available resources. The default scheduler > parameters are quite conservative in order not to overload the other > systems but this can be tunned considering each setup. > Our case has just one physical host which is scheduled to allocate just one virtual machine. > There are huge improvements in performance in OpenNebula 2.2 and > OpenNebula 3.0 in this area. > Ok, I will check some newer versions. > 3.- Increase Boot times depends directly on the hypervisor. This usually > increases when starting multiple VMs in the same host at the same time. > I agree, but this isn't the worst case of time increasing, it's small compared with the *pend* state. Cheers, Vinicius Vielmo Cogo
