qemu: Add range checking for scheduler tunables when changed by API
The quota and period tunables for cpu scheduler accept only a certain range of values. When changing the live configuration invalid values get rejected. This check is not performed when changing persistent config. This patch adds a separate range check, that improves error messages when changing live config and adds the check for persistent config. This check is done only when using the API. It is still possible to specify invalid values in the XML.
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.
