When user does not specify any model for scsi controller, or worse, no controller at all, but libvirt automatically adds scsi controller with no model, we are not searching for virtio-scsi and thus this can fail for example on qemu which doesn't support lsi logic adapter. This means that when qemu on x86 doesn't support lsi53c895a and the user adds the following to an XML without any scsi controller: <disk ...> ... <target dev='sda'> </disk> libvirt fails like this: # virsh define asdf.xml error: Failed to define domain from asdf.xml error: internal error Unable to determine model for scsi controller Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=974943 Signed-off-by: Martin Kletzander <mkletzan@xxxxxxxxxx> --- src/qemu/qemu_command.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index 0e517f2..aff1768 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -703,6 +703,8 @@ qemuSetScsiControllerModel(virDomainDefPtr def, *model = VIR_DOMAIN_CONTROLLER_MODEL_SCSI_IBMVSCSI; } else if (virQEMUCapsGet(qemuCaps, QEMU_CAPS_SCSI_LSI)) { *model = VIR_DOMAIN_CONTROLLER_MODEL_SCSI_LSILOGIC; + } else if (virQEMUCapsGet(qemuCaps, QEMU_CAPS_VIRTIO_SCSI)) { + *model = VIR_DOMAIN_CONTROLLER_MODEL_SCSI_VIRTIO_SCSI; } else { virReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("Unable to determine model for scsi controller")); -- 1.8.3.2 -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
