A "ide-drive" device can be either a hard disk or a CD-ROM, if there is ",media=cdrom" specified for the backend, it's a CD-ROM, otherwise it's a hard disk. Upstream qemu splitted "ide-drive" into "ide-hd" and "ide-cd" since commit 1f56e32, and ",media=cdrom" is not required for ide-cd anymore. "ide-drive" is still supported for backwards compatibility, but no doubt we should go foward. --- src/qemu/qemu_capabilities.c | 4 ++ src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 26 +++++++++++++++- tests/qemuhelptest.c | 3 +- .../qemuxml2argv-disk-ide-drive-split.args | 8 +++++ .../qemuxml2argv-disk-ide-drive-split.xml | 32 ++++++++++++++++++++ tests/qemuxml2argvtest.c | 3 ++ 7 files changed, 74 insertions(+), 3 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-ide-drive-split.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-ide-drive-split.xml diff --git a/src/qemu/qemu_capabilities.c b/src/qemu/qemu_capabilities.c index c4b04ae..1f999a7 100644 --- a/src/qemu/qemu_capabilities.c +++ b/src/qemu/qemu_capabilities.c @@ -156,6 +156,8 @@ VIR_ENUM_IMPL(qemuCaps, QEMU_CAPS_LAST, "scsi-disk.channel", "scsi-block", "scsi-cd", + + "ide-cd", /* 90 */ ); struct qemu_feature_flags { @@ -1450,6 +1452,8 @@ qemuCapsParseDeviceStr(const char *str, virBitmapPtr flags) qemuCapsSet(flags, QEMU_CAPS_SCSI_BLOCK); if (strstr(str, "scsi-cd")) qemuCapsSet(flags, QEMU_CAPS_SCSI_CD); + if (strstr(str, "ide-cd")) + qemuCapsSet(flags, QEMU_CAPS_IDE_CD); return 0; } diff --git a/src/qemu/qemu_capabilities.h b/src/qemu/qemu_capabilities.h index 5ebffdc..e664f29 100644 --- a/src/qemu/qemu_capabilities.h +++ b/src/qemu/qemu_capabilities.h @@ -124,6 +124,7 @@ enum qemuCapsFlags { QEMU_CAPS_SCSI_DISK_CHANNEL = 87, /* Is scsi-disk.channel available? */ QEMU_CAPS_SCSI_BLOCK = 88, /* -device scsi-block */ QEMU_CAPS_SCSI_CD = 89, /* -device scsi-cd */ + QEMU_CAPS_IDE_CD = 90, /* -device ide-cd */ QEMU_CAPS_LAST, /* this must always be the last item */ }; diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index afe5db8..9a02a80 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -1971,6 +1971,9 @@ qemuBuildDriveStr(virConnectPtr conn ATTRIBUTE_UNUSED, if ((disk->bus == VIR_DOMAIN_DISK_BUS_SCSI)) { if (!qemuCapsGet(qemuCaps, QEMU_CAPS_SCSI_CD)) virBufferAddLit(&opt, ",media=cdrom"); + } else if (disk->bus == VIR_DOMAIN_DISK_BUS_IDE) { + if (!qemuCapsGet(qemuCaps, QEMU_CAPS_IDE_CD)) + virBufferAddLit(&opt, ",media=cdrom"); } else { virBufferAddLit(&opt, ",media=cdrom"); } @@ -2194,7 +2197,16 @@ qemuBuildDriveDevStr(virDomainDefPtr def, _("target must be 0 for ide controller")); goto error; } - virBufferAddLit(&opt, "ide-drive"); + + if (qemuCapsGet(qemuCaps, QEMU_CAPS_IDE_CD)) { + if (disk->device == VIR_DOMAIN_DISK_DEVICE_CDROM) + virBufferAddLit(&opt, "ide-cd"); + else + virBufferAddLit(&opt, "ide-hd"); + } else { + virBufferAddLit(&opt, "ide-drive"); + } + virBufferAsprintf(&opt, ",bus=ide.%d,unit=%d", disk->info.addr.drive.bus, disk->info.addr.drive.unit); @@ -2285,12 +2297,22 @@ qemuBuildDriveDevStr(virDomainDefPtr def, _("bus must be 0 for ide controller")); goto error; } + if (disk->info.addr.drive.target != 0) { qemuReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", _("target must be 0 for ide controller")); goto error; } - virBufferAddLit(&opt, "ide-drive"); + + if (qemuCapsGet(qemuCaps, QEMU_CAPS_IDE_CD)) { + if (disk->device == VIR_DOMAIN_DISK_DEVICE_CDROM) + virBufferAddLit(&opt, "ide-cd"); + else + virBufferAddLit(&opt, "ide-hd"); + } else { + virBufferAddLit(&opt, "ide-drive"); + } + virBufferAsprintf(&opt, ",bus=ahci%d.%d", disk->info.addr.drive.controller, disk->info.addr.drive.unit); diff --git a/tests/qemuhelptest.c b/tests/qemuhelptest.c index a01c389..d23b35a 100644 --- a/tests/qemuhelptest.c +++ b/tests/qemuhelptest.c @@ -676,7 +676,8 @@ mymain(void) QEMU_CAPS_CPU_HOST, QEMU_CAPS_FSDEV_WRITEOUT, QEMU_CAPS_SCSI_BLOCK, - QEMU_CAPS_SCSI_CD); + QEMU_CAPS_SCSI_CD, + QEMU_CAPS_IDE_CD); return ret == 0 ?
