When I run
virsh blkiotune alias --weight 100
I receive:

error: Unable to change blkio parameters
error: this function is not supported by the connection driver: blkio
cgroup isn't mounted

But I have mounted blkio:

cgroup /dev/cgroup/cpu cgroup rw,relatime,cpu 0 0
cgroup /dev/cgroup/cpuacct cgroup rw,relatime,cpuacct 0 0
cgroup /dev/cgroup/devices cgroup rw,relatime,devices 0 0
cgroup /dev/cgroup/blkio cgroup rw,relatime,blkio 0 0
cgroup /dev/cgroup/freezer cgroup rw,relatime,freezer 0 0
cgroup /dev/cgroup/cpuset cgroup rw,relatime,cpuset 0 0

why it is not worked?
