The supported libvirt types are 'validated' by the typed switch...case statement so it's not possible to run into a vbox value that the driver does not recognize. The patches that follow are for dumpxml and those do get updated to handle StorageBus_SAS (the new one introduced in this series) in patch #12 (see vboxGenerateMediumName change) and in patch #15 where vboxDumpDisks is changed to use typed switch statement on storageBus.

All options to add disk devices to controller are disabled when VM is running. Neither quick web search returned anything useful regarding hot-add disk support on VBOX. Having said that, the original behavior was, IIRC, the reason why I actually started working on this series. According to our tech support they have ran into a couple of cases where the OS would BSOD (some legacy Windows OS e.g. 2000 or XP) when there was a controller (without a disk) attached to VM that the OS did not handle well. It sounded very strange to me but I've been told it was not a one-off case though I personally haven't reproduced it. Unfortunately, I won't be able to provide more details as we no longer use VBox internally (migrated to KVM) so those potential test cases are no longer around. > > > diff --git a/src/vbox/vbox_common.c b/src/vbox/vbox_common.c > > index 2bd891efb..9d45e4a76 100644 > > --- a/src/vbox/vbox_common.c > > +++ b/src/vbox/vbox_common.c > > @@ -406,6 +406,160 @@ static char *vboxGenerateMediumName(PRUint32 > > storageBus, > > return name; > > } > > > > + > > +static int > > +vboxSetStorageController(virDomainControllerDefPtr controller, > > + vboxDriverPtr data, > > + IMachine *machine) > > +{ > > +PRUnichar *controllerName = NULL; > > +PRInt32 vboxModel = StorageControllerType_Null; > > +PRInt32 vboxBusType = StorageBus_Null; > > +IStorageController *vboxController = NULL; > > +nsresult rc = 0; > > +char *debugName = NULL; > > +int ret = -1; > > + > > +/* libvirt controller type => vbox bus type */ > > +switch ((virDomainControllerType) controller->type) { > > +case VIR_DOMAIN_CONTROLLER_TYPE_FDC: > > +VBOX_UTF8_TO_UTF16(VBOX_CONTROLLER_FLOPPY_NAME, > > ); > > +vboxBusType = StorageBus_Floppy; > > + > > +break; > > +case VIR_DOMAIN_CONTROLLER_TYPE_IDE: > > +VBOX_UTF8_TO_UTF16(VBOX_CONTROLLER_IDE_NAME, > > ); > > +vboxBusType = StorageBus_IDE; > > + > > +break; > > +case VIR_DOMAIN_CONTROLLER_TYPE_SCSI: > > +VBOX_UTF8_TO_UTF16(VBOX_CONTROLLER_SCSI_NAME, > > ); > > +vboxBusType = StorageBus_SCSI; > > + > > +break; > > +case VIR_DOMAIN_CONTROLLER_TYPE_SATA: > > +VBOX_UTF8_TO_UTF16(VBOX_CONTROLLER_SATA_NAME, > > ); > > +vboxBusType = StorageBus_SATA; > > > I think prior to this patch - there should be a patch that "manages" > all > those range check differences, storageBus comparison checks, etc. for > VIR_DOMAIN_CONTROLLER_TYPE_SATA that end up in future patches. > > John > > > + > > +break; > > +case VIR_DOMAIN_CONTROLLER_TYPE_VIRTIO_SERIAL: > > +case VIR_DOMAIN_CONTROLLER_TYPE_CCID: > > +case VIR_DOMAIN_CONTROLLER_TYPE_USB: > > +case VIR_DOMAIN_CONTROLLER_TYPE_PCI: > > +case VIR_DOMAIN_CONTROLLER_TYPE_LAST: > > +virReportError(VIR_ERR_CONFIG_UNSUPPORTED, > > + _("The vbox driver does not support %s > > controller type"), > > + virDomainControllerTypeToString(controller- > > >type)); > > +return -1; > > +} > > + > > +/* libvirt scsi model => vbox scsi model */ > > +if (controller->type == VIR_DOMAIN_CONTROLLER_TYPE_SCSI) { > > +switch ((virDomainControllerModelSCSI) controller->model) > > { > > +

This patch left me with a concern. Up to this point vboxAttachDrives would add at least one controller for each type supported regardless of whether the VM used it. After this patch only those controllers defined in the VM XML will be added. Which would seem to be fine, except for the case of hotplug which I wasn't clear whether vbox support or not. Let's say the VM is defined with and IDE controller, if someone tried to add a SCSI disk after startup, then there'd be no SCSI controller already present. > diff --git a/src/vbox/vbox_common.c b/src/vbox/vbox_common.c > index 2bd891efb..9d45e4a76 100644 > --- a/src/vbox/vbox_common.c > +++ b/src/vbox/vbox_common.c > @@ -406,6 +406,160 @@ static char *vboxGenerateMediumName(PRUint32 storageBus, > return name; > } > > + > +static int > +vboxSetStorageController(virDomainControllerDefPtr controller, > + vboxDriverPtr data, > + IMachine *machine) > +{ > +PRUnichar *controllerName = NULL; > +PRInt32 vboxModel = StorageControllerType_Null; > +PRInt32 vboxBusType = StorageBus_Null; > +IStorageController *vboxController = NULL; > +nsresult rc = 0; > +char *debugName = NULL; > +int ret = -1; > + > +/* libvirt controller type => vbox bus type */ > +switch ((virDomainControllerType) controller->type) { > +case VIR_DOMAIN_CONTROLLER_TYPE_FDC: > +VBOX_UTF8_TO_UTF16(VBOX_CONTROLLER_FLOPPY_NAME, ); > +vboxBusType = StorageBus_Floppy; > + > +break; > +case VIR_DOMAIN_CONTROLLER_TYPE_IDE: > +VBOX_UTF8_TO_UTF16(VBOX_CONTROLLER_IDE_NAME, ); > +vboxBusType = StorageBus_IDE; > + > +break; > +case VIR_DOMAIN_CONTROLLER_TYPE_SCSI: > +VBOX_UTF8_TO_UTF16(VBOX_CONTROLLER_SCSI_NAME, ); > +vboxBusType = StorageBus_SCSI; > + > +break; > +case VIR_DOMAIN_CONTROLLER_TYPE_SATA: > +VBOX_UTF8_TO_UTF16(VBOX_CONTROLLER_SATA_NAME, ); > +vboxBusType = StorageBus_SATA; I think prior to this patch - there should be a patch that "manages" all those range check differences, storageBus comparison checks, etc. for VIR_DOMAIN_CONTROLLER_TYPE_SATA that end up in future patches.

[libvirt] [PATCH v2 10/15] vbox: Process element in domain XML
This patch enables the VBOX driver to process the element in domain XML through which one can now customize the controller model. Since VirtualBox has two distinct SAS and SCSI they do not "map" directly to libvirt XML, he VBOX driver uses to create SAS controller in VBOX VM. Additionally once can set model on the IDE controller to be one of "piix3", "piix4" or "ich6". --- src/vbox/vbox_common.c | 214 ++--- src/vbox/vbox_common.h | 8 ++ 2 files changed, 176 insertions(+), 46 deletions(-) diff --git a/src/vbox/vbox_common.c b/src/vbox/vbox_common.c index 2bd891efb..9d45e4a76 100644 --- a/src/vbox/vbox_common.c +++ b/src/vbox/vbox_common.c @@ -406,6 +406,160 @@ static char *vboxGenerateMediumName(PRUint32 storageBus, return name; } + +static int +vboxSetStorageController(virDomainControllerDefPtr controller, + vboxDriverPtr data, + IMachine *machine) +{ +PRUnichar *controllerName = NULL; +PRInt32 vboxModel = StorageControllerType_Null; +PRInt32 vboxBusType = StorageBus_Null; +IStorageController *vboxController = NULL; +nsresult rc = 0; +char *debugName = NULL; +int ret = -1; + +/* libvirt controller type => vbox bus type */ +switch ((virDomainControllerType) controller->type) { +case VIR_DOMAIN_CONTROLLER_TYPE_FDC: +VBOX_UTF8_TO_UTF16(VBOX_CONTROLLER_FLOPPY_NAME, ); +vboxBusType = StorageBus_Floppy; + +break; +case VIR_DOMAIN_CONTROLLER_TYPE_IDE: +VBOX_UTF8_TO_UTF16(VBOX_CONTROLLER_IDE_NAME, ); +vboxBusType = StorageBus_IDE; + +break; +case VIR_DOMAIN_CONTROLLER_TYPE_SCSI: +VBOX_UTF8_TO_UTF16(VBOX_CONTROLLER_SCSI_NAME, ); +vboxBusType = StorageBus_SCSI; + +break; +case VIR_DOMAIN_CONTROLLER_TYPE_SATA: +VBOX_UTF8_TO_UTF16(VBOX_CONTROLLER_SATA_NAME, ); +vboxBusType = StorageBus_SATA; + +break; +case VIR_DOMAIN_CONTROLLER_TYPE_VIRTIO_SERIAL: +case VIR_DOMAIN_CONTROLLER_TYPE_CCID: +case VIR_DOMAIN_CONTROLLER_TYPE_USB: +case VIR_DOMAIN_CONTROLLER_TYPE_PCI: +case VIR_DOMAIN_CONTROLLER_TYPE_LAST: +virReportError(VIR_ERR_CONFIG_UNSUPPORTED, + _("The vbox driver does not support %s controller type"), + virDomainControllerTypeToString(controller->type)); +return -1; +} + +/* libvirt scsi model => vbox scsi model */ +if (controller->type == VIR_DOMAIN_CONTROLLER_TYPE_SCSI) { +switch ((virDomainControllerModelSCSI) controller->model) { +case VIR_DOMAIN_CONTROLLER_MODEL_SCSI_LSILOGIC: +case VIR_DOMAIN_CONTROLLER_MODEL_SCSI_AUTO: +vboxModel = StorageControllerType_LsiLogic; + +break; +case VIR_DOMAIN_CONTROLLER_MODEL_SCSI_BUSLOGIC: +vboxModel = StorageControllerType_BusLogic; + +break; +case VIR_DOMAIN_CONTROLLER_MODEL_SCSI_LSISAS1068: +/* in vbox, lsisas has a dedicated SAS bus type with no model */ +VBOX_UTF16_FREE(controllerName); +VBOX_UTF8_TO_UTF16(VBOX_CONTROLLER_SAS_NAME, ); +vboxBusType = StorageBus_SAS; + +break; +case VIR_DOMAIN_CONTROLLER_MODEL_SCSI_VMPVSCSI: +case VIR_DOMAIN_CONTROLLER_MODEL_SCSI_IBMVSCSI: +case VIR_DOMAIN_CONTROLLER_MODEL_SCSI_VIRTIO_SCSI: +case VIR_DOMAIN_CONTROLLER_MODEL_SCSI_LSISAS1078: +case VIR_DOMAIN_CONTROLLER_MODEL_SCSI_LAST: +virReportError(VIR_ERR_CONFIG_UNSUPPORTED, + _("The vbox driver does not support %s SCSI " + "controller model"), + virDomainControllerModelSCSITypeToString(controller->model)); +goto cleanup; +} +/* libvirt ide model => vbox ide model */ +} else if (controller->type == VIR_DOMAIN_CONTROLLER_TYPE_IDE) { +switch ((virDomainControllerModelIDE) controller->model) { +case VIR_DOMAIN_CONTROLLER_MODEL_IDE_PIIX3: +vboxModel = StorageControllerType_PIIX3; + +break; +case VIR_DOMAIN_CONTROLLER_MODEL_IDE_PIIX4: +vboxModel = StorageControllerType_PIIX4; + +break; +case VIR_DOMAIN_CONTROLLER_MODEL_IDE_ICH6: +vboxModel = StorageControllerType_ICH6; + +break; +case VIR_DOMAIN_CONTROLLER_MODEL_IDE_LAST: +virReportError(VIR_ERR_CONFIG_UNSUPPORTED, + _("The vbox driver does not support %s IDE " + "controller model"), + virDomainControllerModelIDETypeToString(controller->model)); +goto cleanup; +} +} + +VBOX_UTF16_TO_UTF8(controllerName, ); +VIR_DEBUG("Adding VBOX storage controller (name: %s, busType: %d)", + debugName, vboxBusType); + +rc =
