hi all,

im am trying to allocate cpu to the various domains using a bvt scheduler. so now lets say i want to give the first virtual machine a weight of 1 and the second a weight of 2. this should result in domain1 using 33% of the cpu and domain2 66%. however since xm sched-bvt takes inverse of the weights as input so i do 1/1 and 1/2 and hence do "xm sched-bvt vm1 2 0 0 0 0" for the first domain and "xm sched-bvt vm2 1 0 0 0 0" for the second domain. This however results in domain 1 using 40% and domain 2 using 60% of cpu as shown by "xm top". Can anyone please point out where am i going wrong. any help will be appreciated!

regards,
hardeep
