[Localization Question] Cluster Policy "power_saving"
This is a multi-part message in MIME format. --------------030502000209020304030303 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Hi oVirt developers, I am currently translating documentation and I would like to ask you one question on power_saving Cluster Policy, in order to understand the mechanism properly so that I can translate accurately. (Please excuse me -- this might be a basic concept, but it is a bit confusing for me) My understanding is that when this is selected, the Manager tries to shut down a host which has the lowest usage within the cluster (so that it can save the power). In order to shut it down, VMs running on that host need to be migrated to other host. Which host will be the destination? Would it be the host with the second lowest usage rate? Many thanks in advance, Yuko Katabami --------------030502000209020304030303 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit <html> <head> <meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"> </head> <body bgcolor="#FFFFFF" text="#000000"> Hi oVirt developers,<br> <br> I am currently translating documentation and I would like to ask you one question on power_saving Cluster Policy,<br> in order to understand the mechanism properly so that I can translate accurately.<br> (Please excuse me -- this might be a basic concept, but it is a bit confusing for me)<br> <br> My understanding is that when this is selected, the Manager tries to shut down a host which has the lowest usage within the cluster (so that it can save the power). <br> In order to shut it down, VMs running on that host need to be migrated to other host.<br> Which host will be the destination?<br> Would it be the host with the second lowest usage rate?<br> <br> Many thanks in advance,<br> <br> Yuko Katabami<br> <div class="moz-signature"><font color="#000000" face="arial, sans-serif" size="2"><br> <br> <br> </font> </div> </body> </html> --------------030502000209020304030303--
No it must choose host that have cpu utilization between low and high thresholds, so if you have power_saving policy with HighUtilization 80 and LowUtilization 20, policy will try to find host that have cpu utilization between this two values, and if he found such host, will migrate vms on it(if found number of such hosts will choose host randomly). If you don't have such host, vms will stay on old host.
