https://bugzilla.redhat.com/show_bug.cgi?id=1142631 Commit id 'e0e290552' added a check to determine if the same bus had the same target value.

Also added a DO_TEST_DIFFERENT to exhibit the issue Signed-off-by: John Ferlan <jferlan(a)redhat.com&gt; --- src/conf/domain_conf.c | 3 +- .../qemuxml2argv-disk-same-targets.xml | 35 ++++++++++++++++++++++ tests/qemuxml2argvtest.c | 3 ++ 3 files changed, 39 insertions(+), 2 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-same-targets.xml diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index b10f6cd..7855bcb 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -12590,8 +12590,7 @@ virDomainDiskDefDstDuplicates(virDomainDefPtr def) for (i = 1; i < def->ndisks; i++) { for (j = 0; j < i; j++) { - if (def->disks[i]->bus == def->disks[j]->bus && - STREQ(def->disks[i]->dst, def->disks[j]->dst)) { + if (STREQ(def->disks[i]->dst, def->disks[j]->dst)) { virReportError(VIR_ERR_XML_ERROR, _("target '%s' duplicated for disk sources " "'%s' and '%s'"), diff --git a/tests/qemuxml2argvdata/qemuxml2argv-disk-same-targets.xml b/tests/qemuxml2argvdata/qemuxml2argv-disk-same-targets.xml new file mode 100644 index 0000000..3276ce5 --- /dev/null +++ b/tests/qemuxml2argvdata/qemuxml2argv-disk-same-targets.xml @@ -0,0 +1,35 @@ +<domain type='qemu'> + <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/bin/qemu</emulator> + <disk type='block' device='disk'> + <source dev='/dev/HostVG/QEMUGuest1'/> + <target dev='hda' bus='ide'/> + </disk> + <disk type='file' device='disk'> + <source file='/tmp/usbdisk.img'/> + <target dev='sda' bus='usb'/> + </disk> + <disk type='file' device='disk'> + <source file='/tmp/idedisk.img'/> + <target dev='sda' bus='ide'/> + </disk> + <disk type='file' device='disk'> + <source file='/tmp/scsidisk.img'/> + <target dev='sda' bus='scsi'/> + </disk> + <memballoon model='virtio'/> + </devices> +</domain> diff --git a/tests/qemuxml2argvtest.c b/tests/qemuxml2argvtest.c index be82dd2..b066681 100644 --- a/tests/qemuxml2argvtest.c +++ b/tests/qemuxml2argvtest.c @@ -882,6 +882,9 @@ mymain(void) QEMU_CAPS_DEVICE); DO_TEST("disk-snapshot", QEMU_CAPS_DRIVE, QEMU_CAPS_DRIVE_CACHE_V2, QEMU_CAPS_DRIVE_FORMAT); + DO_TEST_FAILURE("disk-same-targets", + QEMU_CAPS_DRIVE, QEMU_CAPS_DEVICE, QEMU_CAPS_SCSI_LSI, + QEMU_CAPS_DEVICE_USB_STORAGE, QEMU_CAPS_NODEFCONFIG); DO_TEST("event_idx", QEMU_CAPS_DRIVE, QEMU_CAPS_VIRTIO_BLK_EVENT_IDX,
