Hi ,
I was previously using xen and currently moved to KVM. I am using libvirt to manage these
VMs. In den's credit scheduler , I had the ability to set a cap on the cpu usage for a
VM. But I was not able to find a similar substitute in KVM. I find that we can use cgroups
to provide shares for VM but that will be more like weight based and it doesn't set a
hard cap for that VM. I tried using cpulimit but I find it inaccurate and we can give
values only between 0-100. Thus, I think it cannot support multi core environments. Can
any one suggest a method to set a hard limit on a VM's cpu usage? Thank you.
