[libvirt] [PATCH-RFC] Change libxl to use Xen 4.2 interface

This patch changes libxl to use the interface in Xen 4.2. It is provided as an example, not intended to go in to libvirt as-is since it removes all support for libxl from Xen 4.1. It also still has some cruft (extra void casts on parameters) and the device model info population is not written. It has been tested with simple domain create/destroy. --- src/libxl/libxl_conf.c | 134 +++++++++------ src/libxl/libxl_conf.h | 8 +- src/libxl/libxl_driver.c | 430 ++++++++++++++++++++++++++-------------------- 3 files changed, 326 insertions(+), 246 deletions(-) diff --git a/src/libxl/libxl_conf.c b/src/libxl/libxl_conf.c index 62621f1..c5b5561 100644 --- a/src/libxl/libxl_conf.c +++ b/src/libxl/libxl_conf.c @@ -41,7 +41,7 @@ #include "capabilities.h" #include "libxl_driver.h" #include "libxl_conf.h" - +#include "libxl_utils.h" #define VIR_FROM_THIS VIR_FROM_LIBXL @@ -358,18 +358,29 @@ libxlMakeCapabilitiesInternal(const char *hostmachine, } static int -libxlMakeDomCreateInfo(virDomainDefPtr def, libxl_domain_create_info *c_info) +libxlMakeDomCreateInfo(libxlDriverPrivatePtr driver, virDomainDefPtr def, libxl_domain_create_info *c_info) { char uuidstr[VIR_UUID_STRING_BUFLEN]; - libxl_init_create_info(c_info); + libxl_domain_create_info_init(c_info); + + if (STREQ(def->os.type, "hvm")) + c_info->type = LIBXL_DOMAIN_TYPE_HVM; + else + c_info->type = LIBXL_DOMAIN_TYPE_PV; - c_info->hvm = STREQ(def->os.type, "hvm"); if ((c_info->name = strdup(def->name)) == NULL) { virReportOOMError(); goto error; } + if (def->seclabel.type == VIR_DOMAIN_SECLABEL_STATIC) { + if (libxl_flask_context_to_sid(driver->ctx, def->seclabel.label, strlen(def->seclabel.label), &c_info->ssidref)) { + libxlError(VIR_ERR_INTERNAL_ERROR, + _("libxenlight failed to resolve security label '%s'"), def->seclabel.label); + } + } + virUUIDFormat(def->uuid, uuidstr); if (libxl_uuid_from_string(&c_info->uuid, uuidstr) ) { libxlError(VIR_ERR_INTERNAL_ERROR, @@ -380,7 +391,7 @@ libxlMakeDomCreateInfo(virDomainDefPtr def, libxl_domain_create_info *c_info) return 0; error: - libxl_domain_create_info_destroy(c_info); + libxl_domain_create_info_dispose(c_info); return -1; } @@ -403,9 +414,9 @@ libxlMakeDomBuildInfo(virDomainDefPtr def, libxl_domain_config *d_config) return -1; } - libxl_init_build_info(b_info, &d_config->c_info); + libxl_domain_build_info_init(b_info); - b_info->hvm = hvm; + b_info->type = hvm ?
