Hello, Is it possible to measure the time that needed for the allocation and the configuraiton of the network, during the instantiation of a VM?

Thank you

I can guess from your question that you are interested in the various times that an operation takes when VM is in the making. You can get your all questions answered by hooking into the rabbitmq queue of the OpenStack. You can find many code snippets on the internet about how to do that. Once you get the information you just have to analyze that and extract the information of your interest. This can only be possible when you sit on the queue and perform action once the request comes in with the specific UUID. Then trach that UUID and get to that information that is of use to you. There are certain tools available but you will also have to tailor them to fit your need and it will be much of a hassle. So I would recommend hooking rabbitmq and listen for events as they come in and then calculate the time of anything you would want.

I hope that helps !!

Hello I think your question is not much clear. allocation on network to VM during instantiation depends on many factors. 1. Hardware which are using ( if hardware having high performance ). 2. Type of network you are using ( ovs, dpdk sriov ie)
