Commands to manage network filter are moved from virsh.c to virsh-nwfilter.c, with a few helpers for network filter command use.
* virsh.c: Remove network filter commands and a few helpers. (vshCommandOptNWFilter, and vshCommandOptNWFilterBy) * virsh-nwfilter.c: New file, filled with network filter commands and its helpers. --- tools/virsh-nwfilter.c | 310 ++++++++++++++++++++++++++++++++++++++++++++++++ tools/virsh.c | 294 +--------------------------------------------- 2 files changed, 312 insertions(+), 292 deletions(-) create mode 100644 tools/virsh-nwfilter.c diff --git a/tools/virsh-nwfilter.c b/tools/virsh-nwfilter.c new file mode 100644 index 0000000..4b4996a --- /dev/null +++ b/tools/virsh-nwfilter.c @@ -0,0 +1,310 @@ +/* + * virsh-domain.c: Commands to manage network filters + * + * Copyright (C) 2005, 2007-2012 Red Hat, Inc + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public + * License as published by the Free Software Foundation; either + * version 2.1 of the License, or (at your option) any later version. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
