[libvirt] [PATCH v4] qemu: Allow the user to specify vendor and product for disk
QEMU supports setting vendor and product strings for disk since 1.2.0 (only scsi-disk, scsi-hd, scsi-cd support it), this patch exposes it with new XML elements <vendor> and <product> of disk device. v3 - v4: * Per Paolo's feedback, allows all printable chars. --- docs/formatdomain.html.in | 11 +++++ docs/schemas/domaincommon.rng | 14 ++++++ src/conf/domain_conf.c | 44 ++++++++++++++++++++ src/conf/domain_conf.h | 2 + src/libvirt_private.syms | 1 + src/qemu/qemu_command.c | 29 +++++++++++++ src/util/util.c | 12 +++++ src/util/util.h | 1 + ...qemuxml2argv-disk-scsi-disk-vpd-build-error.xml | 35 ++++++++++++++++ .../qemuxml2argv-disk-scsi-disk-vpd.args | 13 ++++++ .../qemuxml2argv-disk-scsi-disk-vpd.xml | 38 +++++++++++++++++ tests/qemuxml2argvtest.c | 8 ++++ tests/qemuxml2xmltest.c | 2 + 13 files changed, 210 insertions(+), 0 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-scsi-disk-vpd-build-error.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-scsi-disk-vpd.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-scsi-disk-vpd.xml diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index 6a3b976..903c069 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -1657,6 +1657,17 @@ of 16 hexadecimal digits. <span class='since'>Since 0.10.1</span> </dd> + <dt><code>vendor</code></dt> + <dd>If present, this element specifies the vendor of a virtual hard + disk or CD-ROM device.
