Re: [libvirt] [PATCH 0/2] qemu: Fix incorrect qemuDomainGetBlockIoTune() results

The qemuDomainGetBlockIoTune() function was returning incorrect results as I discovered on Fedora Virt Test Day: https://fedoraproject.org/wiki/QA:Testcase_Virtualization_IO_Throttling The problem is that I/O limits can be set but I only see zeroes when displaying them with "virsh blkdeviotune <domain> <device>" on a domain with two disks. First, we're comparing guest device names ("virtio-blk-0") instead of host device names ("drive-virtio-blk-0"). Second, the JSON monitor code has inverted string compare logic so we were skipping the device we were looking for. These patches make "virsh blkdeviotune" report correct results.
