Hello, I just tried to validate the minimal <hostdev>-example from <http://libvirt.org/formatdomain.html#elementsUSB>, which failed. <domain type='xen'> <name>N</name> <memory>123456</memory> <bootloader>/usr/bin/pygrub</bootloader> <os> <type arch='x86_64' machine='xenpv'>linux</type> </os> <devices> <hostdev mode='subsystem' type='pci'> <source> <address bus='0x06' slot='0x00' function='0x0'/> </source> </hostdev> </devices> </domain> This is caused by domain.rng requiring either all three attributes ("mode", "type", and the undocumented "managed") to be defined or non of them; just a subset of them is not allowed because the all reside in the same <optional>-section. Since I don't know, which of the three attributes must be defined in concert, and which is optional, I just post a patch to make all three self-standing. diff --git a/docs/schemas/domain.rng b/docs/schemas/domain.rng index 8b215f3..11a987e 100644 --- a/docs/schemas/domain.rng +++ b/docs/schemas/domain.rng @@ -1731,12 +1731,16 @@ <value>capabilities</value> </choice> </attribute> + </optional> + <optional> <attribute name="type"> <choice> <value>usb</value> <value>pci</value> </choice> </attribute> + </optional> + <optional> <attribute name="managed"> <choice> <value>yes</value> Also the "managed" attribute should be documented on that page. Any internal documentation (read: code) for that?
