Hi, guys. I want to change block I/O throttle using 'virsh blkdeviotune' with vm not running, it reported an error: # virsh blkdeviotune instance-000000dc /dev/loop0 --total-bytes-sec 20000000 --total-iops-sec 20 --config error: Unable to change block I/O throttle error: unsupported configuration: block I/O throttling not supported with this QEMU binary I can do this when the vm is running. Is it a bug? How can I fix this problem.
It just looks strange, as you can tune when the VM is active. Because the qemu capabilities is collected during the qemu driver starts up, which is independant with the domain states. Probably you will want to debug the qemu capabilities collecting process.
