[libvirt] [PATCH 3/4] qemu: Add caps to indentify if setting wwn is supported by qemu

This assumes ide-drive.wwn, ide-hd.wwn, ide-cd.wwn were supported at the same time, similar for scsi-disk.wwn, scsi-hd.wwn, and scsi-cd.wwn. So only two new caps (QEMU_CAPS_IDE_DRIVE_WWN, and QEMU_CAPS_SCSI_DISK_WWN) are introduced. --- src/qemu/qemu_capabilities.c | 4 ++++ src/qemu/qemu_capabilities.h | 2 ++ 2 files changed, 6 insertions(+), 0 deletions(-) diff --git a/src/qemu/qemu_capabilities.c b/src/qemu/qemu_capabilities.c index ed85b6f..e7afe18 100644 --- a/src/qemu/qemu_capabilities.c +++ b/src/qemu/qemu_capabilities.c @@ -176,6 +176,8 @@ VIR_ENUM_IMPL(qemuCaps, QEMU_CAPS_LAST, "disable-s3", "disable-s4", /* 105 */ + "ide-drive.wwn", + "scsi-disk.wwn", ); struct qemu_feature_flags { @@ -1497,6 +1499,8 @@ qemuCapsParseDeviceStr(const char *str, virBitmapPtr flags) qemuCapsSet(flags, QEMU_CAPS_VIRTIO_BLK_SCSI); if (strstr(str, "scsi-disk.channel")) qemuCapsSet(flags, QEMU_CAPS_SCSI_DISK_CHANNEL); + if (strstr(str, "scsi-disk.wwn")) + qemuCapsSet(flags, QEMU_CAPS_SCSI_DISK_WWN); if (strstr(str, "scsi-block")) qemuCapsSet(flags, QEMU_CAPS_SCSI_BLOCK); if (strstr(str, "scsi-cd")) diff --git a/src/qemu/qemu_capabilities.h b/src/qemu/qemu_capabilities.h index 49d64e5..954e51d 100644 --- a/src/qemu/qemu_capabilities.h +++ b/src/qemu/qemu_capabilities.h @@ -141,6 +141,8 @@ enum qemuCapsFlags { QEMU_CAPS_BLOCKIO = 103, /* -device ...logical_block_size & co */ QEMU_CAPS_DISABLE_S3 = 104, /* S3 BIOS Advertisement on/off */ QEMU_CAPS_DISABLE_S4 = 105, /* S4 BIOS Advertisement on/off */ + QEMU_CAPS_IDE_DRIVE_WWN = 106, /* Is ide-drive.wwn available? */ + QEMU_CAPS_SCSI_DISK_WWN = 107, /* Is scsi-disk.wwn available? */ QEMU_CAPS_LAST, /* this must always be the last item */ }; -- 1.7.7.3
