Hi,

where can I find some information about how xen-3's schedulers work and
their parameters? The default setup completely locks up all domU domains
on my machine (VIA Nehemiah EPIA board) whenever the dom0 domain is
doing CPU/IO-intensive stuff, and the only solution I found so far is to
adjust the weight of each domain (eg xm sched-sedf <domID> 0 0 0 0 1 for
each domain) but this seems to be a waste of CPU capacity.

I read

sedf_scheduler_mini-HOWTO.txt
http://wiki.xensource.com/xenwiki/Scheduling
man xm

but none of them give enough information for me to know what to do. I'd
apprechiate any pointers.

Thanks,
Michael
