[Xen-users] One domU locks up entire system? Scheduling?

[Dirk Estreng <dirk.estreng@xxxxxx>]

Hi there,

running xen 2.0.7 on a suse 9.3 box in 32Bit mode. I am experiencing a heavy
slowdown 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.
