When blkdeviotune was first committed in 0.9.8, we had the limitation that setting one value reset all others. But bytes and iops should be relatively independent. Furthermore, setting tuning values on a live domain followed by dumpxml did not output the new settings. * src/qemu/qemu_driver.c (qemuDiskPathToAlias): Add parameter, and update callers. (qemuDomainSetBlockIoTune): Don't lose previous unrelated settings. Make live changes reflect to dumpxml output. * tools/virsh.pod (blkdeviotune): Update documentation.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
