Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.

whether or not previous return value is -1, the following codes will be
executed for a inactive guest in src/qemu/qemu_driver.c:
ret = virDomainSaveConfig(driver->configDir, persistentDef);
and if everything is okay, 'ret' is assigned to 0, the previous 'ret'
will be overwritten, this patch will fix this issue.
* src/qemu/qemu_driver.c: avoid return value is overwritten when give a argument
in out of blkio weight range for a inactive guest.
* how to reproduce?
% virsh blkiotune ${guestname} --weight 10
% echo $?
Note: guest must be inactive, argument 10 in out of blkio weight range,
and can get a error information by checking libvirtd.log, however,
virsh hasn't raised any error information, and return value is 0.

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.
