[Xen-users] CPU management in XEN

["Atle Rudshaug" <atle.rudshaug@xxxxxxxxx>]

I am doing some research about CPU utilization in Xen. My scenario is running multiple domU's with Oracle databases running on them. Is there any way to prevent one domU using 100% of the servers resources, e.g. in case of an error, making the other domU's very slow and unresponsive? How much of this is already done automatically in Xen by the schedulers? I have been looking at the sched-sedf option, but I am not sure what the different options will do ( e.g. period, slice, latency...). Whats the difference between the sedf, bev and credit schedulers? (I can't find the credit one on my installation Xen 3.0.2).
