Since af2a1f0587d88656f2c14265a63fbc11ecbd924e, qemuDomainGetNumaParameters() returns invalid value for a running guest. The problem is that it is getting the information from cgroups, but the parent cgroup is being left alone since the mentioned commit. Since the running guest's XML is in sync with cgroups, there is no need to look into cgroups (unless someone changes the configuration behind libvirt's back). Returning the info from the definition fixes a bug and is also a cleanup. Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1221047 Signed-off-by: Martin Kletzander <mkletzan@redhat.com>
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.
