Re: [libvirt] [PATCH v4 2/8] libxl: pass driver config to libxlMakeDomBuildInfo

Preparation for global nestedhvm configuration - libxlMakeDomBuildInfo needs access to libxlDriverConfig. No functional change. Adjusting tests require slightly more mockup functions, because of libxlDriverConfigNew() call. --- Changes since v3: - new patch, preparation --- src/libxl/libxl_conf.c | 8 +++++--- src/libxl/libxl_conf.h | 2 +- src/libxl/libxl_domain.c | 2 +- tests/libxlxml2domconfigtest.c | 20 +++++++++++++------- tests/virmocklibxl.c | 25 +++++++++++++++++++++++++ 5 files changed, 45 insertions(+), 12 deletions(-) diff --git a/src/libxl/libxl_conf.c b/src/libxl/libxl_conf.c index 2d2a707..8cced29 100644 --- a/src/libxl/libxl_conf.c +++ b/src/libxl/libxl_conf.c @@ -271,10 +271,11 @@ libxlMakeChrdevStr(virDomainChrDefPtr def, char **buf) static int libxlMakeDomBuildInfo(virDomainDefPtr def, - libxl_ctx *ctx, + libxlDriverConfigPtr cfg, virCapsPtr caps, libxl_domain_config *d_config) { + libxl_ctx *ctx = cfg->ctx; libxl_domain_build_info *b_info = &d_config->b_info; int hvm = def->os.type == VIR_DOMAIN_OSTYPE_HVM; size_t i; @@ -2288,16 +2289,17 @@ int libxlBuildDomainConfig(virPortAllocatorPtr graphicsports, virDomainDefPtr def, const char *channelDir LIBXL_ATTR_UNUSED, - libxl_ctx *ctx, + libxlDriverConfigPtr cfg,
