[libvirt] [PATCH v2] qemu: Split scsi-disk into into scsi-hd and scsi-cd
A "scsi-disk" 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. But upstream qemu splitted "scsi-disk" into "scsi-hd" and "scsi-cd" since commit b443ae, and ",media=cdrom" is not required for scsi-cd anymore. "scsi-disk" is still supported for backwards compatibility, but no doubt we should go foward. --- No changes since v1 --- src/qemu/qemu_capabilities.c | 3 +++ src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 39 +++++++++++++++++++++++++++++++-------- tests/qemuhelptest.c | 6 ++++-- tests/qemuxml2argvtest.c | 3 +++ 5 files changed, 42 insertions(+), 10 deletions(-) diff --git a/src/qemu/qemu_capabilities.c b/src/qemu/qemu_capabilities.c index fd4ca4d..4e22f3e8 100644 --- a/src/qemu/qemu_capabilities.c +++ b/src/qemu/qemu_capabilities.c @@ -159,6 +159,7 @@ VIR_ENUM_IMPL(qemuCaps, QEMU_CAPS_LAST, "block-job-sync", /* 90 */ "block-job-async", + "scsi-cd", ); struct qemu_feature_flags { @@ -1451,6 +1452,8 @@ qemuCapsParseDeviceStr(const char *str, virBitmapPtr flags) qemuCapsSet(flags, QEMU_CAPS_SCSI_DISK_CHANNEL); if (strstr(str, "scsi-block")) qemuCapsSet(flags, QEMU_CAPS_SCSI_BLOCK); + if (strstr(str, "scsi-cd")) + qemuCapsSet(flags, QEMU_CAPS_SCSI_CD); return 0; } diff --git a/src/qemu/qemu_capabilities.h b/src/qemu/qemu_capabilities.h index 6550d59..2aba502 100644 --- a/src/qemu/qemu_capabilities.h +++ b/src/qemu/qemu_capabilities.h @@ -126,6 +126,7 @@ enum qemuCapsFlags { QEMU_CAPS_TRANSACTION = 89, /* transaction monitor command */ QEMU_CAPS_BLOCKJOB_SYNC = 90, /* RHEL 6.2 block_job_cancel */ QEMU_CAPS_BLOCKJOB_ASYNC = 91, /* qemu 1.1 block-job-cancel */ + QEMU_CAPS_SCSI_CD = 92, /* -device scsi-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 c82f5bc..ff82b26 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -1978,8 +1978,14 @@ qemuBuildDriveStr(virConnectPtr conn ATTRIBUTE_UNUSED, else virBufferAsprintf(&opt, "if=%s", bus); - if (disk->device == VIR_DOMAIN_DISK_DEVICE_CDROM) - virBufferAddLit(&opt, ",media=cdrom"); + if (disk->device == VIR_DOMAIN_DISK_DEVICE_CDROM) { + if ((disk->bus == VIR_DOMAIN_DISK_BUS_SCSI)) { + if (!qemuCapsGet(qemuCaps, QEMU_CAPS_SCSI_CD)) + virBufferAddLit(&opt, ",media=cdrom"); + } else { + virBufferAddLit(&opt, ",media=cdrom"); + } + } if (qemuCapsGet(qemuCaps, QEMU_CAPS_DEVICE)) { virBufferAsprintf(&opt, ",id=%s%s", QEMU_DRIVE_HOST_PREFIX, disk->info.alias); @@ -2229,10 +2235,19 @@ qemuBuildDriveDevStr(virDomainDefPtr def, goto error; } - if (disk->device == VIR_DOMAIN_DISK_DEVICE_LUN) + if (disk->device == VIR_DOMAIN_DISK_DEVICE_LUN) { virBufferAddLit(&opt, "scsi-block"); - else - virBufferAddLit(&opt, "scsi-disk"); + } else { + if (qemuCapsGet(qemuCaps, QEMU_CAPS_SCSI_CD)) { + if (disk->device == VIR_DOMAIN_DISK_DEVICE_CDROM) + virBufferAddLit(&opt, "scsi-cd"); + else + virBufferAddLit(&opt, "scsi-hd"); + } else { + virBufferAddLit(&opt, "scsi-disk"); + } + } + virBufferAsprintf(&opt, ",bus=scsi%d.%d,scsi-id=%d", disk->info.addr.drive.controller, disk->info.addr.drive.bus, @@ -2255,10 +2270,18 @@ qemuBuildDriveDevStr(virDomainDefPtr def, } } - if (disk->device != VIR_DOMAIN_DISK_DEVICE_LUN) - virBufferAddLit(&opt, "scsi-disk"); - else + if (disk->device != VIR_DOMAIN_DISK_DEVICE_LUN) { + if (qemuCapsGet(qemuCaps, QEMU_CAPS_SCSI_CD)) { + if (disk->device == VIR_DOMAIN_DISK_DEVICE_CDROM) + virBufferAddLit(&opt, "scsi-cd"); + else + virBufferAddLit(&opt, "scsi-hd"); + } else { + virBufferAddLit(&opt, "scsi-disk"); + } + } else { virBufferAddLit(&opt, "scsi-block"); + } virBufferAsprintf(&opt, ",bus=scsi%d.0,channel=%d,scsi-id=%d,lun=%d", disk->info.addr.drive.controller, diff --git a/tests/qemuhelptest.c b/tests/qemuhelptest.c index 05fdc4d..a01c389 100644 --- a/tests/qemuhelptest.c +++ b/tests/qemuhelptest.c @@ -605,7 +605,8 @@ mymain(void) QEMU_CAPS_VIRTIO_BLK_SCSI, QEMU_CAPS_VIRTIO_BLK_SG_IO, QEMU_CAPS_DRIVE_COPY_ON_READ, - QEMU_CAPS_CPU_HOST); + QEMU_CAPS_CPU_HOST, + QEMU_CAPS_SCSI_CD); DO_TEST("qemu-1.0", 1000000, 0, 0, QEMU_CAPS_VNC_COLON, QEMU_CAPS_NO_REBOOT, @@ -674,7 +675,8 @@ mymain(void) QEMU_CAPS_VIRTIO_BLK_SG_IO, QEMU_CAPS_CPU_HOST, QEMU_CAPS_FSDEV_WRITEOUT, - QEMU_CAPS_SCSI_BLOCK); + QEMU_CAPS_SCSI_BLOCK, + QEMU_CAPS_SCSI_CD); return ret == 0 ?

A "scsi-disk" 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.
But upstream qemu splitted "scsi-disk" into "scsi-hd" and "scsi-cd" since commit b443ae, and ",media=cdrom" is not required for scsi-cd anymore. "scsi-disk" is still supported for backwards compatibility, but no doubt we should go foward.
