Hi,
    Is there a way to give different network bandwidth caps to virtual 
machines? Or to generalize it further , is there support for weighted device 
scheduling like there is for cpu scheduling?
    Please help me regarding this, the help will be greatly appreciated.

Thanks and Regards,
Saransh.


For network limiting you can use the rate= option in the vif parameter
an example:

vif = ['ip=15.25.117.44', 'rate=10MB/s']


I can't think of a disk one, but that doesn't mean that it doesn't exist...

Cheers,
Todd
