qemu: Reject unsupported tuning in session mode
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>
