Re: [libvirt] [PATCH 5/7] qemu: propagate iotune settings to all disks in the group

Currently upon successfull call to qemu's implementation of virDomainSetBlockIoTune iotune settings are changed only for the disk given in API if the disk is in iotune group while we need to change the settings for all disks in the group.
