I also use all the livbirt tools, if there si any sol Misaotra, Thanks, Merci. You should be able to limit cpu utilization using cgroups -- libvir-list mailing list libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
Re: [libvirt] cpulimit and kvm process
Hello, is there any way how to set some initial nice? In XML maybe...? Thank you. Dne 1.10.2010 14:15, Richard W.M.

KVM processes are just like Linux processes, so you can pin them and renice them. There is support for pinning virtual CPUs to physical CPUs in libvirt, eg: virsh vcpupin GuestName 0 0 but you can also use Linux tools. tuna is one such program which I think is in Fedora, or upstream here: http://git.kernel.org/?p=linux/kernel/git/acme/tuna.git;a=summary Another tool is renice.
