Hi all,
I am having following test setup
Host machine=Rhel 6.1 enterprise with kvm
Number of virtual machines=2
Guest machine os=rhel6.1 enterprise
I am using kvm virtual environment using libvirt
Now when iam specifying blkio.weight parameter on one guest=1000
And on other guest=500
Now as per cgroup bandwidth should be propotionally distributed on both
the guests,but when I analysed the disk read write bytes ,it seems that
cgroup is not doing any impact.
Bandwidth on both guests is not as per the weight assigned to the guest.
Please help if anybody has used cgroup on kvm environment
Regards
