Re: [libvirt] [PATCH 5/8] qemu: use vfio-pci on commandline when appropriate

The device option for vfio-pci is nearly identical to that for pci-assign - only the configfd parameter isn't supported (or needed). Checking for presence of the bootindex parameter is done separately from constructing the commandline, similar to how it is done for pci-assign. --- src/qemu/qemu_command.c | 48 ++++++++++++++++++++++++++++++++++++++---------- src/qemu/qemu_hotplug.c | 13 ++++++++++++- 2 files changed, 50 insertions(+), 11 deletions(-) @@ -7850,12 +7855,23 @@ qemuBuildCommandLine(virConnectPtr conn, " supported for PCI and USB devices")); goto error; } else { - if (hostdev->source.subsys.type == VIR_DOMAIN_HOSTDEV_SUBSYS_TYPE_PCI && - !virQEMUCapsGet(qemuCaps, QEMU_CAPS_PCI_BOOTINDEX)) { - virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", - _("booting from assigned PCI devices is not" - " supported with this version of qemu")); - goto error; + if (hostdev->source.subsys.type == VIR_DOMAIN_HOSTDEV_SUBSYS_TYPE_PCI) { + if (hostdev->source.subsys.u.pci.backend + == VIR_DOMAIN_HOSTDEV_PCI_BACKEND_TYPE_VFIO) { + if (!virQEMUCapsGet(qemuCaps, QEMU_CAPS_VFIO_PCI_BOOTINDEX)) { + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", + _("booting from PCI devices assigned with VFIO " + "is not supported with this version of qemu"));
