virtxml was doing its own loading of the libosinfo database, and gvir_designer_init() was loading it a second time. By adding a GVirDesignerDomain::osinfo_db property, applications can share the same OsinfoDb as libvirt-designer. The association is made per libvirt-designer domain for more flexibility. If no OsinfoDb is associated with a domain when needed, libvirt-designer will automatically try to load it. --- examples/virtxml.c | 2 ++ libvirt-designer/libvirt-designer-domain.c | 49 +++++++++++++++++++++++++++- libvirt-designer/libvirt-designer-internal.h | 3 -- libvirt-designer/libvirt-designer-main.c | 12 ------- libvirt-designer/libvirt-designer-main.h | 2 ++ libvirt-designer/libvirt-designer.sym | 1 + 6 files changed, 53 insertions(+), 16 deletions(-) diff --git a/examples/virtxml.c b/examples/virtxml.c index a68843d..be6ee7a 100644 --- a/examples/virtxml.c +++ b/examples/virtxml.c @@ -559,6 +559,8 @@ main(int argc, char *argv[]) } domain = gvir_designer_domain_new(os, platform, caps);
