There's been a bug report appearing on the qemu-devel list, that libvirt is unable to pass spaces in disk serial number [1]. Not only our RNG schema forbids that, the code is not prepared either. However, with a bit of escaping (if needed) we can allow spaces there. 1: https://lists.gnu.org/archive/html/qemu-devel/2015-02/msg04041.html Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com&gt; --- docs/schemas/domaincommon.rng | 2 +- src/qemu/qemu_command.c | 5 ++-- .../qemuxml2argvdata/qemuxml2argv-disk-serial.args | 6 +++++ .../qemuxml2argvdata/qemuxml2argv-disk-serial.xml | 27 ++++++++++++++++++++++ tests/qemuxml2argvtest.c | 5 ++++ 5 files changed, 42 insertions(+), 3 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-serial.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-serial.xml diff --git a/docs/schemas/domaincommon.rng b/docs/schemas/domaincommon.rng index f41ca43..09bd921 100644 --- a/docs/schemas/domaincommon.rng +++ b/docs/schemas/domaincommon.rng @@ -5067,7 +5067,7 @@ </define> <define name="diskSerial"> <data type="string"> - <param name="pattern">[A-Za-z0-9_\.\+\-]+</param> + <param name="pattern">[A-Za-z0-9_\.\+\- ]+</param> </data> </define> <define name="bridgeMode"> diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index 7853125..b9adef6 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -2633,7 +2633,7 @@ qemuBuildIoEventFdStr(virBufferPtr buf, } #define QEMU_SERIAL_PARAM_ACCEPTED_CHARS \ - "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-_" + "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-_ " static int qemuSafeSerialParamValue(const char *value) @@ -3616,7 +3616,8 @@ qemuBuildDriveStr(virConnectPtr conn, virQEMUCapsGet(qemuCaps, QEMU_CAPS_DRIVE_SERIAL)) { if (qemuSafeSerialParamValue(disk->serial) < 0) goto error; - virBufferAsprintf(&opt, ",serial=%s", disk->serial); + virBufferAddLit(&opt, ",serial="); + virBufferEscapeShell(&opt, disk->serial); } if (disk->cachemode) { diff --git a/tests/qemuxml2argvdata/qemuxml2argv-disk-serial.args b/tests/qemuxml2argvdata/qemuxml2argv-disk-serial.args new file mode 100644 index 0000000..8b08cfb --- /dev/null +++ b/tests/qemuxml2argvdata/qemuxml2argv-disk-serial.args @@ -0,0 +1,6 @@ +LC_ALL=C PATH=/bin HOME=/home/test USER=test LOGNAME=test QEMU_AUDIO_DRV=none \ +/usr/libexec/qemu-kvm -S -M pc -cpu qemu32 -m 214 -smp 1 -nographic -nodefaults \ +-monitor unix:/tmp/test-monitor,server,nowait -no-acpi -boot c -usb \ +-drive 'file=/dev/HostVG/QEMUGuest1,if=none,id=drive-ide0-0-1,serial='\'' WD-WMAP9A966149'\''' \ +-device ide-drive,bus=ide.0,unit=1,drive=drive-ide0-0-1,id=ide0-0-1 \ +-device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x3 diff --git a/tests/qemuxml2argvdata/qemuxml2argv-disk-serial.xml b/tests/qemuxml2argvdata/qemuxml2argv-disk-serial.xml new file mode 100644 index 0000000..0fe75f3 --- /dev/null +++ b/tests/qemuxml2argvdata/qemuxml2argv-disk-serial.xml @@ -0,0 +1,27 @@ +<domain type='kvm'> + <name>QEMUGuest1</name> + <uuid>c7a5fdbd-edaf-9455-926a-d65c16db1809</uuid> + <memory unit='KiB'>219136</memory> + <currentMemory unit='KiB'>219136</currentMemory> + <vcpu placement='static'>1</vcpu> + <os> + <type arch='i686' machine='pc'>hvm</type> + <boot dev='hd'/> + </os> + <clock offset='utc'/> + <on_poweroff>destroy</on_poweroff> + <on_reboot>restart</on_reboot> + <on_crash>destroy</on_crash> + <devices> + <emulator>/usr/libexec/qemu-kvm</emulator> + <disk type='block' device='disk'> + <source dev='/dev/HostVG/QEMUGuest1'/> + <target dev='hda' bus='ide'/> + <serial> WD-WMAP9A966149</serial> + <address type='drive' controller='0' bus='0' target='0' unit='1'/> + </disk> + <controller type='usb' index='0'/> + <controller type='ide' index='0'/> + <memballoon model='virtio'/> + </devices> +</domain> diff --git a/tests/qemuxml2argvtest.c b/tests/qemuxml2argvtest.c index 16f325e..3032d1b 100644 --- a/tests/qemuxml2argvtest.c +++ b/tests/qemuxml2argvtest.c @@ -904,6 +904,11 @@ mymain(void) QEMU_CAPS_DEVICE, QEMU_CAPS_SCSI_BLOCK, QEMU_CAPS_VIRTIO_BLK_SG_IO, QEMU_CAPS_SCSI_LSI, QEMU_CAPS_VIRTIO_SCSI); + DO_TEST("disk-serial", + QEMU_CAPS_KVM, + QEMU_CAPS_DEVICE, + QEMU_CAPS_DRIVE, + QEMU_CAPS_DRIVE_SERIAL); DO_TEST("graphics-vnc", QEMU_CAPS_VNC); DO_TEST("graphics-vnc-socket", QEMU_CAPS_VNC); -- 2.0.5
