When domain is started with setting that cannot be done, i.e. those that require cgroups, there is no error reported and it succeeds without any message whatsoever. When setting with API, virsh, an error is reported, but only due to the fact that no cgroups are mounted (priv->cgroup == NULL). Given the above it seems reasonable to reject such unsupported settings. This patch effectively changes the error message from: $ virsh -c qemu:///session schedinfo dummy Scheduler : Unknown error: Requested operation is not valid: cgroup CPU controller is not mounted to: $ virsh -c qemu:///session schedinfo dummy Scheduler : Unknown error: Operation not supported: CPU tuning is not available in session mode Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1023366 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.
