[libvirt] [PATCH 13/13] Tweak USB hostdevice XML handling

When attaching a USB host device based on vendor/product, libvirt will resolve the vendor/product into a device/bus pair. This means that when printing XML we should allow device/bus info to be printed at any time if present * src/conf/domain_conf.c, docs/schemas/domain.rng: Allow USB device bus info alongside vendor/product --- docs/schemas/domain.rng | 7 ++++++- src/conf/domain_conf.c | 5 +++-- 2 files changed, 9 insertions(+), 3 deletions(-) diff --git a/docs/schemas/domain.rng b/docs/schemas/domain.rng index 827ff6f..bb6d00d 100644 --- a/docs/schemas/domain.rng +++ b/docs/schemas/domain.rng @@ -1179,7 +1179,12 @@ <group> <element name="source"> <choice> - <ref name="usbproduct"/> + <group> + <ref name="usbproduct"/> + <optional> + <ref name="usbaddress"/> + </optional> + </group> <ref name="usbaddress"/> <element name="address"> <ref name="pciaddress"/> diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index b434fc5..766993c 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -5244,11 +5244,12 @@ virDomainHostdevDefFormat(virConnectPtr conn, def->source.subsys.u.usb.vendor); virBufferVSprintf(buf, " <product id='0x%.4x'/>\n", def->source.subsys.u.usb.product); - } else { + } + if (def->source.subsys.u.usb.bus || + def->source.subsys.u.usb.device) virBufferVSprintf(buf, " <address bus='%d' device='%d'/>\n", def->source.subsys.u.usb.bus, def->source.subsys.u.usb.device); - } } else if (def->source.subsys.type == VIR_DOMAIN_HOSTDEV_SUBSYS_TYPE_PCI) { virBufferVSprintf(buf, " <address domain='0x%.4x' bus='0x%.2x' slot='0x%.2x' function='0x%.1x'/>\n", def->source.subsys.u.pci.domain, -- 1.6.5.2
