Xen users - Dec 2005 - rate and cpu limits

Is there a way in Xen to place a limit on cpu utilisation and network
resources ? This is not the number of cpu which a domain can use, i want to
limit the cpu time/ units a domain can use maximum. Hence utilising the
maximum cpu resources available to the host.

Same applies to network resources. Is it possible to rate limit a domain for
example limit one domain at 1MB/sec and another at 512kb/sec ??

The reason i want to do this is inside some domains there would be constant
network and cpu utilisation. Now i don''t want the other domains to be
affected by this. They should be able to get a constant network share as
well.

Thanks.

Anand

Looking at xm help, i found this

  Scheduler Commands:
   sched-bvt <Parameters>           Set Borrowed Virtual Time scheduler
parameters
   sched-bvt-ctxallow <Allow>       Set the BVT scheduler context switch
allowance
   sched-sedf <Parameters>          Set simple EDF parameters

and also found and entry inside the wiki at
http://wiki.xensource.com/xenwiki/Scheduling, however there are no examples
which i can refer to. The closest i found was a post at
http://lists.xensource.com/archives/html/xen-users/2005-12/msg00432.html.
However when i try to run

xm sched-bvt 0 10 0 0 0 0

errors are returned

Error: (22, ''Invalid argument'')

Any help will be appreciated.
