Look, you've now posted basically the same question on a number of different places: on the Xen UserVoice page, on someone's G+ profile, and even mailed people individually. Anything other than posting to the xen-devel list was inappropriate behavior. It's not our job to help you with your project and hold your hand. If you can't read the xl man page or do a Google search to figure out how to set the weight, why do you expect us to think you're going to be able to improve the scheduler -- one of the most complicated and difficult parts of Xen? Try reading this page and see if it helps you. http://wiki.xen.org/wiki/Asking_Xen_Devel_Questions -George ^ permalink raw reply [flat|nested] 11+ messages in thread

That's still nowhere near specific enough. I'm sorry to be blunt, but if that's the best question you can ask, then either you haven't really made an effort to come to grips with the code yourself, or you've made the effort and are still completely lost. If you haven't made the effort, there's no reason for me to make an effort. And if you have made the effort and are still this lost, I'm afraid there's not much I can do for you. -George [-- Attachment #1.2: Type: text/html, Size: 1696 bytes --] [-- Attachment #2: Type: text/plain, Size: 126 bytes --] _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel ^ permalink raw reply [flat|nested] 11+ messages in thread
