<div dir="ltr"><span style="font-family:arial,sans-serif;font-size:13px">Hi everyone,</span><div style="font-family:arial,sans-serif;font-size:13px"><br></div><div style="font-family:arial,sans-serif;font-size:13px">I'm currently taking part of a project at the Federal University of Campina Grande called fogbow, which aims on providing an energy efficient scheduler and an opportunistic compute node (which deactivates the service if the host isn't idle) on top of openstack.</div>
<div style="font-family:arial,sans-serif;font-size:13px"><br></div><div style="font-family:arial,sans-serif;font-size:13px">Regarding the opportunistic aspect of the project, we're planning on using powernap (<a href="http://manpages.ubuntu.com/manpages/lucid/man8/powernap.8.html" target="_blank">http://manpages.ubuntu.com/manpages/lucid/man8/powernap.8.html</a>) to tell if the host is idle or not.<br clear="all">
<div><br></div><div>Finally, my question is: what do you guys think would be the best way for a powernap action script to interact with nova-compute in order to stop all running instances and disable the host? </div><div>
<br></div><div>Would killing and respawning the nova-compute be an elegant way of doing that in your opinion? Or do RPC calls sound better?</div><div><br></div><div>Thanks in advance</div><div><br></div></div><div><div dir="ltr">
