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 +1-919-301-3266 Libvirt virtualization library http://libvirt.org
