Re: [Xen-users] cpu_weight and cpu_cap

I just did a search for 'cpu_cap' and another for 'cpu_weight' in the list archives and got zero results. Weird.
Anyway, I have a PV VM that might try and use too many resources. How can I use 'cpu_cap' and 'cpu_weight' to control that? Is there any
sort of reference doc that describes these settings? Maybe examples? I can kindof guess what cpu_cap does, but cpu_weight could mean anything.
Something to look at:
Usage: xm sched-credit -d <Domain> [-w[=WEIGHT]|-c[=CAP]]
Get/set credit scheduler parameters. -d DOMAIN, --domain=DOMAIN Domain to modify -w WEIGHT, --weight=WEIGHT Weight (int) -c CAP, --cap=CAP Cap (int)
OR!
If there is a better way to manage VM prioritisation, please let me
know. Or even more generally, any best practices to keep a VM from making other VMS too sluggish?
Thanks! -Dylan
