From f3d43dfd9a8a870160f0aaf7bd692b9ce4827ead Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Thomas=20Wei=C3=9Fschuh?= Date: Mon, 13 Sep 2021 15:04:19 +0200 Subject: [PATCH] vmdk: allow specification of tools version MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit VMDK files support an attribute that represents the version of the guest tools that are installed on the disk. This attribute is used by vSphere before a machine has been started to determine if the VM has the guest tools installed. This is important when configuring "Operating system customizations" in vSphere, as it checks for the presence of the guest tools before allowing those customizations. Thus when the VM has not yet booted normally it would be impossible to customize it, therefore preventing a customized first-boot. The attribute should not hurt on disks that do not have the guest tools installed and indeed the VMware tools also unconditionally add this attribute. (Defaulting to the value "2147483647", as is done in this patch) Signed-off-by: Thomas Weißschuh Message-Id: <20210913130419.13241-1-thomas.weissschuh.ext@zeiss.com> [hreitz: Added missing '#' in block-core.json] Signed-off-by: Hanna Reitz --- block/vmdk.c | 24 ++++++++++++++++++++---- qapi/block-core.json | 3 +++ 2 files changed, 23 insertions(+), 4 deletions(-) diff --git a/block/vmdk.c b/block/vmdk.c index fb4cc9da90..0dfab6e941 100644 --- a/block/vmdk.c +++ b/block/vmdk.c @@ -60,6 +60,7 @@ #define VMDK_ZEROED (-3) #define BLOCK_OPT_ZEROED_GRAIN "zeroed_grain" +#define BLOCK_OPT_TOOLSVERSION "toolsversion" typedef struct { uint32_t version; @@ -2344,6 +2345,7 @@ static int coroutine_fn vmdk_co_do_create(int64_t size, BlockdevVmdkAdapterType adapter_type, const char *backing_file, const char *hw_version, + const char *toolsversion, bool compat6, bool zeroed_grain, vmdk_create_extent_fn extent_fn, @@ -2384,7 +2386,8 @@ static int coroutine_fn vmdk_co_do_create(int64_t size, "ddb.geometry.cylinders = \"%" PRId64 "\"\n" "ddb.geometry.heads = \"%" PRIu32 "\"\n" "ddb.geometry.sectors = \"63\"\n" - "ddb.adapterType = \"%s\"\n"; + "ddb.adapterType = \"%s\"\n" + "ddb.toolsVersion = \"%s\"\n"; ext_desc_lines = g_string_new(NULL); @@ -2401,6 +2404,9 @@ static int coroutine_fn vmdk_co_do_create(int64_t size, if (!hw_version) { hw_version = "4"; } + if (!toolsversion) { + toolsversion = "2147483647"; + } if (adapter_type != BLOCKDEV_VMDK_ADAPTER_TYPE_IDE) { /* that's the number of heads with which vmware operates when @@ -2525,7 +2531,8 @@ static int coroutine_fn vmdk_co_do_create(int64_t size, size / (int64_t)(63 * number_heads * BDRV_SECTOR_SIZE), number_heads, - BlockdevVmdkAdapterType_str(adapter_type)); + BlockdevVmdkAdapterType_str(adapter_type), + toolsversion); desc_len = strlen(desc); /* the descriptor offset = 0x200 */ if (!split && !flat) { @@ -2617,6 +2624,7 @@ static int coroutine_fn vmdk_co_create_opts(BlockDriver *drv, BlockdevVmdkAdapterType adapter_type_enum; char *backing_file = NULL; char *hw_version = NULL; + char *toolsversion = NULL; char *fmt = NULL; BlockdevVmdkSubformat subformat; int ret = 0; @@ -2649,6 +2657,7 @@ static int coroutine_fn vmdk_co_create_opts(BlockDriver *drv, adapter_type = qemu_opt_get_del(opts, BLOCK_OPT_ADAPTER_TYPE); backing_file = qemu_opt_get_del(opts, BLOCK_OPT_BACKING_FILE); hw_version = qemu_opt_get_del(opts, BLOCK_OPT_HWVERSION); + toolsversion = qemu_opt_get_del(opts, BLOCK_OPT_TOOLSVERSION); compat6 = qemu_opt_get_bool_del(opts, BLOCK_OPT_COMPAT6, false); if (strcmp(hw_version, "undefined") == 0) { g_free(hw_version); @@ -2692,14 +2701,15 @@ static int coroutine_fn vmdk_co_create_opts(BlockDriver *drv, .opts = opts, }; ret = vmdk_co_do_create(total_size, subformat, adapter_type_enum, - backing_file, hw_version, compat6, zeroed_grain, - vmdk_co_create_opts_cb, &data, errp); + backing_file, hw_version, toolsversion, compat6, + zeroed_grain, vmdk_co_create_opts_cb, &data, errp); exit: g_free(backing_fmt); g_free(adapter_type); g_free(backing_file); g_free(hw_version); + g_free(toolsversion); g_free(fmt); g_free(desc); g_free(path); @@ -2782,6 +2792,7 @@ static int coroutine_fn vmdk_co_create(BlockdevCreateOptions *create_options, opts->adapter_type, opts->backing_file, opts->hwversion, + opts->toolsversion, false, opts->zeroed_grain, vmdk_co_create_cb, @@ -3031,6 +3042,11 @@ static QemuOptsList vmdk_create_opts = { .help = "VMDK hardware version", .def_value_str = "undefined" }, + { + .name = BLOCK_OPT_TOOLSVERSION, + .type = QEMU_OPT_STRING, + .help = "VMware guest tools version", + }, { .name = BLOCK_OPT_SUBFMT, .type = QEMU_OPT_STRING, diff --git a/qapi/block-core.json b/qapi/block-core.json index ce2c1352cb..69698a4ffe 100644 --- a/qapi/block-core.json +++ b/qapi/block-core.json @@ -4691,6 +4691,8 @@ # @adapter-type: The adapter type used to fill in the descriptor.
