libvirt users - Apr 2014 - Re: disk iotune

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

Yes.  'virsh blkdeviotune' will do it (which makes calls to the
underlying virDomainSetBlockIoTune() API).
