Does this help? echo "cfq" > /sys/block/sda/queue/scheduler -- Timothy Doyle CEO Quantact Hosting Solutions, Inc. tim@xxxxxxxxxxxx http://www.quantact.com Dirk Estreng wrote: Hi there, running xen 2.0.7 on a suse 9.3 box in 32Bit mode. I am experiencing a heavyslowdown of the entire dom0 and all other domUs if *one* domU gets under heavy load. So the whole system is quite unusable (DoS) if only one DomU is running wild. Is there any way to tighten this domU by adjusting something like scheduling?? the documentation around scheduling seems very rare - what are your experiences concerning this?The dom0 is a dual opteron box with a *fast* 3ware SATA disk subsystem. _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
