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...

Hi, reading the below[1] on blkdeviotune made me wonder if we can dynamically change the values after the VM is already running using iotune. Is it supported? Thanks, Doron [1] https://fedoraproject.org/wiki/QA:Testcase_Virtualization_IO_Throttling

Yes. 'virsh blkdeviotune' will do it (which makes calls to the underlying virDomainSetBlockIoTune() API). -- Eric Blake eblake redhat com +1-919-301...

Hi, is there a way to configure blkio via libvirt (xml)? Regards Erkan -- ?ber den grenzen mu? die freiheit wohl wolkenlos sein
