Hm, maybe I was not clear then. Let me try to rephrase. As far as I understand, and as far as I saw during my tests, the blkio controller only works for sync I/O requests (eg dd with oflag=direct). Buffered I/O is not part of the control. And since a VM's I/O is most likely buffered in some fashion, this does not have any effect. That's what my tests showed. Did your tests show something different? Maybe I did things wrong then. Regards Dominik -- libvir-list mailing list libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
