[libvirt] [libvirt-glib v7 2/5] gconfig: Add GVirConfigDomainHostdev

Add API to read and write domain/devices/hostdev nodes. This patch only adds the baseclass and hence is not useful on it's own. A more specific subclass to represent PCI devices will be added in a following patch. --- libvirt-gconfig/Makefile.am | 2 + .../libvirt-gconfig-domain-device-private.h | 3 + libvirt-gconfig/libvirt-gconfig-domain-device.c | 2 +- libvirt-gconfig/libvirt-gconfig-domain-hostdev.c | 190 +++++++++++++++++++++ libvirt-gconfig/libvirt-gconfig-domain-hostdev.h | 76 +++++++++ libvirt-gconfig/libvirt-gconfig.h | 1 + libvirt-gconfig/libvirt-gconfig.sym | 10 ++ 7 files changed, 283 insertions(+), 1 deletion(-) create mode 100644 libvirt-gconfig/libvirt-gconfig-domain-hostdev.c create mode 100644 libvirt-gconfig/libvirt-gconfig-domain-hostdev.h diff --git a/libvirt-gconfig/Makefile.am b/libvirt-gconfig/Makefile.am index f308539..a7c6c4e 100644 --- a/libvirt-gconfig/Makefile.am +++ b/libvirt-gconfig/Makefile.am @@ -50,6 +50,7 @@ GCONFIG_HEADER_FILES = \ libvirt-gconfig-domain-graphics-sdl.h \ libvirt-gconfig-domain-graphics-spice.h \ libvirt-gconfig-domain-graphics-vnc.h \ + libvirt-gconfig-domain-hostdev.h \ libvirt-gconfig-domain-input.h \ libvirt-gconfig-domain-interface.h \ libvirt-gconfig-domain-interface-bridge.h \ @@ -141,6 +142,7 @@ GCONFIG_SOURCE_FILES = \ libvirt-gconfig-domain-graphics-sdl.c \ libvirt-gconfig-domain-graphics-spice.c \ libvirt-gconfig-domain-graphics-vnc.c \ + libvirt-gconfig-domain-hostdev.c \ libvirt-gconfig-domain-input.c \ libvirt-gconfig-domain-interface.c \ libvirt-gconfig-domain-interface-bridge.c \ diff --git a/libvirt-gconfig/libvirt-gconfig-domain-device-private.h b/libvirt-gconfig/libvirt-gconfig-domain-device-private.h index 062c0e2..c45e1df 100644 --- a/libvirt-gconfig/libvirt-gconfig-domain-device-private.h +++ b/libvirt-gconfig/libvirt-gconfig-domain-device-private.h @@ -43,6 +43,9 @@ GVirConfigDomainDevice * gvir_config_domain_graphics_new_from_tree(GVirConfigXmlDoc *doc, xmlNodePtr tree); GVirConfigDomainDevice * +gvir_config_domain_hostdev_new_from_tree(GVirConfigXmlDoc *doc, + xmlNodePtr tree); +GVirConfigDomainDevice * gvir_config_domain_interface_new_from_tree(GVirConfigXmlDoc *doc, xmlNodePtr tree); GVirConfigDomainDevice * diff --git a/libvirt-gconfig/libvirt-gconfig-domain-device.c b/libvirt-gconfig/libvirt-gconfig-domain-device.c index 3d2b9b3..8a75cea 100644 --- a/libvirt-gconfig/libvirt-gconfig-domain-device.c +++ b/libvirt-gconfig/libvirt-gconfig-domain-device.c @@ -66,7 +66,7 @@ gvir_config_domain_device_new_from_tree(GVirConfigXmlDoc *doc, } else if (xmlStrEqual(tree->name, (xmlChar*)"lease")) { goto unimplemented; } else if (xmlStrEqual(tree->name, (xmlChar*)"hostdev")) { - goto unimplemented; + return gvir_config_domain_hostdev_new_from_tree(doc, tree); } else if (xmlStrEqual(tree->name, (xmlChar*)"redirdev")) { type = GVIR_CONFIG_TYPE_DOMAIN_REDIRDEV; } else if (xmlStrEqual(tree->name, (xmlChar*)"smartcard")) { diff --git a/libvirt-gconfig/libvirt-gconfig-domain-hostdev.c b/libvirt-gconfig/libvirt-gconfig-domain-hostdev.c new file mode 100644 index 0000000..ce5f8aa --- /dev/null +++ b/libvirt-gconfig/libvirt-gconfig-domain-hostdev.c @@ -0,0 +1,190 @@ +/* + * libvirt-gconfig-domain-hostdev.c: libvirt domain hostdev configuration + * + * Copyright (C) 2016 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.
