Re: [libvirt] [PATCH 4/6] qemu: Wire up disk model=virtio-{non-}transitional

Add new <disk> model values for virtio transitional devices. When combined with bus='virtio': * "virtio-transitional" maps to qemu "virtio-blk-pci-transitional" * "virtio-non-transitional" maps to qemu "virtio-blk-pci-non-transitional" Signed-off-by: Cole Robinson <crobinso(a)redhat.com&gt; --- src/qemu/qemu_command.c | 31 ++++++++++++++++++- src/qemu/qemu_domain_address.c | 2 ++ ...virtio-non-transitional.x86_64-latest.args | 7 +++-- .../virtio-transitional.x86_64-latest.args | 4 +-- .../virtio-non-transitional.xml | 10 ++++-- 5 files changed, 45 insertions(+), 9 deletions(-) diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index 822d5f8669..ca6abea227 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -443,6 +443,33 @@ qemuBuildVirtioDevStr(virBufferPtr buf, return 0; } +static int +qemuBuildVirtioTransitional(virBufferPtr buf, + const char *baseName, + virDomainDeviceAddressType type, + bool transitional, + bool nontransitional) +{ + if (qemuBuildVirtioDevStr(buf, baseName, type) < 0) + return -1; + + if (type != VIR_DOMAIN_DEVICE_ADDRESS_TYPE_PCI && + (transitional || nontransitional)) { + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, + _("virtio transitional models are not supported " + "for address type=%s"), + virDomainDeviceAddressTypeToString(type)); + return -1; + } + + if (transitional) { + virBufferAddLit(buf, "-transitional"); + } else if (nontransitional) { + virBufferAddLit(buf, "-non-transitional"); + } + return 0;
