Re: [libvirt] [PATCH 1/2] Addition of XenAPI support to libvirt
by Sharadha Prabhakar (3P) 14 Mar '10

14 Mar '10

Patch includes 1) Modification of xenapiDomainGetOSType 1) global url and SSL flags removed and placed in private driver struct. 2) SSL verify on url parsed using function similar to the one in ESX. 3) mapDomainPinVcpu updated in xenapi_utils.c diff -Nur ./libvirt_org/src/xenapi/xenapi_driver.c ./libvirt/src/xenapi/xenapi_driver.c --- ./libvirt_org/src/xenapi/xenapi_driver.c 1970-01-01 01:00:00.000000000 +0100 +++ ./libvirt/src/xenapi/xenapi_driver.c 2010-03-04 16:59:01.000000000 +0000 @@ -0,0 +1,1738 @@ + +/* + * xenapi_driver.c: Xen API driver. + * Copyright (C) 2009 Citrix Ltd. + * Sharadha Prabhakar <sharadha.prabhakar(a)citrix.com> +*/ + +#include <config.h> +#include <stdint.h> +#include <unistd.h> +#include <string.h> +#include <stdlib.h> +#include <errno.h> +#include <sys/types.h> +#include <libxml/uri.h> +#include <xen_internal.h> +#include <libxml/parser.h> +#include <curl/curl.h> +#include <xen/api/xen_common.h> +#include <xen/api/xen_vm.h> +#include <xen/api/xen_vm.h> +#include <xen/api/xen_all.h> +#include <xen/api/xen_vm_metrics.h> + +#include "libvirt_internal.h" +#include "libvirt/libvirt.h" +#include "domain_conf.h" +#include "virterror_internal.h" +#include "datatypes.h" +#include "xenapi_driver.h" +#include "xenapi_driver_private.h" +#include "util.h" +#include "uuid.h" +#include "memory.h" +#include "driver.h" +#include "buf.h" +#include "xenapi_utils.h" + + +/* +*getCapsObject +* +*Build the capabilities of the hypervisor +*Return virCapsPtr on success or NULL on failure +*/ +static virCapsPtr +getCapsObject (void) +{ + virCapsPtr caps = virCapabilitiesNew("x86_64", 0, 0);
