I have a CentOS 5.2 Dual-Core Host with two domU's. One domU is for
apache and postfix, the other one is just for BOINC. I thought that I
can configure the XEN credit scheduler in such a manner, that the BOINC
domU only gets CPU resources if the other one, the "important" one, has
nothing else to do.
After a "xm sched-credit -d boinc -w 1" and "xm sched-credit -d web -w
200" I run a CPU benchmark on the "web" domU. I expected that the "web"
domU would get 199% CPU share and the boinc domU just 1%, because the
"web" domU hast 200 times more weight than the BOINC domU. But the
credit scheduler gave both domU's about 100% CPU share.
What am I missing here? xm dmesg shows "(XEN) Using scheduler: SMP Credit Scheduler (credit)" and "xm sched_credit -d web" also confirms that the weight is set correctly.
