[libvirt] [PATCH v2] qemu: Split scsi-disk into into scsi-hd and scsi-cd
by Osier Yang 17 Apr '12

17 Apr '12

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 ?

If console[0] is an alias for serial[0], do not enforce the former to have a PTY source type. This breaks serial consoles on stdio and makes no sense.

[libvirt] OpenSSH authentification in Java libvirt API
by Alexandre Garnier 16 Apr '12

16 Apr '12

Hello, It seems that today you can’t authenticate on a qemu+ssh connection via OpenSSH without having to manually type the password in CLI or a pop-up window, using the Java API for libvirt. Being able to push a String in OpenSSH user input would be an easier and faster solution, for the end-user. Sincerely, Alexandre

I updated part of the documentation that was changed in last few weeks. Screenshot test was updated again a little bit to suit the needs of a documentation and replaced the source codes of previous two tests mentioned in the documentation as it describe just what is needed and has no overhead on the reader. I'm not sure how the numbering goes in this case, but it can be updated later or I can send a v2 in case it needs to be fixed right away.
