Re: [libvirt] [PATCH 3/9] New files to glue domain and storage together

This creates src/conf/domain_storage.h and src/conf/storage_conf.c, which defines a driver contains internal APIs to glue the domain and storage. Currently there is only one API, translateDiskSourcePool, which is to translate the specified pool/volume into the the real underlying disk source. Later patch will implement API. --- src/Makefile.am | 3 ++- src/conf/domain_storage.c | 44 ++++++++++++++++++++++++++++++++++++++++++++ src/conf/domain_storage.h | 37 +++++++++++++++++++++++++++++++++++++ src/libvirt_private.syms | 4 ++++ 4 files changed, 87 insertions(+), 1 deletions(-) create mode 100644 src/conf/domain_storage.c create mode 100644 src/conf/domain_storage.h diff --git a/src/Makefile.am b/src/Makefile.am index 070a089..d664c48 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -203,7 +203,8 @@ DOMAIN_CONF_SOURCES = \ conf/domain_conf.c conf/domain_conf.h \ conf/domain_audit.c conf/domain_audit.h \ conf/domain_nwfilter.c conf/domain_nwfilter.h \ - conf/snapshot_conf.c conf/snapshot_conf.h + conf/snapshot_conf.c conf/snapshot_conf.h \ + conf/domain_storage.c conf/domain_storage.h DOMAIN_EVENT_SOURCES = \ conf/domain_event.c conf/domain_event.h diff --git a/src/conf/domain_storage.c b/src/conf/domain_storage.c new file mode 100644 index 0000000..299e9fd --- /dev/null +++ b/src/conf/domain_storage.c @@ -0,0 +1,44 @@ +/* + * domain_storage.c: Internal APIs to glue domain and storage + * + * Copyright (C) 2013 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.
