Hi All, This series implements a new command "blkiotune" for virsh. A lot of code borrows from memtune. You are able to tune blkio cgroup tunables by this command as follows. Show tunables #virsh blkiotune My_guest weight : 900 Tune tunables(Set IO weight) #virsh blkiotune My_guest --weight 500 #virsh blkiotune My_guest weight : 500 Thanks, Gui -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
