Prior to this patch, for a running dom, the commands: $ virsh blkiotune dom --device-weights /dev/sda,502,/dev/sdb,498 $ virsh blkiotune dom --device-weights /dev/sda,503 $ virsh blkiotune dom weight : 500 device_weight : /dev/sda,503 claim that /dev/sdb no longer has a non-default weight, but directly querying cgroups says otherwise: $ cat /cgroup/blkio/libvirt/qemu/dom/blkio.weight_device 8:0 503 8:16 498 After this patch, an explicit 0 is required to remove a device path from the XML, and omitting a device path that was previously specified leaves that device path untouched in the XML, to match cgroups behavior. * src/qemu/qemu_driver.c (parseBlkioWeightDeviceStr): Rename... (qemuDomainParseDeviceWeightStr): ...and use correct type. (qemuDomainSetBlkioParameters): After parsing string, modify rather than replacing existing table. * tools/virsh.pod (blkiotune): Tweak wording. |
