If disk polling is enabled in virt-manager, those messages will be
logged by libvirt. They are coming from the qemu monitor every time disk
stats info is requested. As far as I know there is no way to disable
logging these messages, though it would certainly be handy since they
will quickly take up a lot of room if virt-manager is left running.

You can disable disk polling in virt-manager via Edit->Preferences
