Re: [libvirt] [PATCH v3] domain.rng vs. formatdomain.html#elementsUSB

The Relax-NG schema for domains regarding <hostdev> doesn't match what's implemented in src/conf/domain_conf.c#virDomainHostdevDefFormat(): The implementation only requires @type, but the schema currently either required none or all three attributes (@mode, @type, and @managed) to be defined together, because they are declared in the same <optional)-section. (@managed is currently even undocumented on <http://libvirt.org/formatdomain.html#elementsUSB>). Thus the following minimal <hostdev>-example fails to validate: <domain type='test'> <name>N</name> <memory>4096</memory> <bootloader>/bin/false</bootloader> <os> <type arch='x86_64' machine='xenpv'>linux</type> </os> <devices> <hostdev type='pci'> <source> <address bus='0x06' slot='0x00' function='0x0'/> </source> </hostdev> </devices> </domain> The schema is changed to match the current implementation: 1. @mode is optional (which defaults to 'subsystem') 2. @type is required 3. @managed is optional (which defaults to 'no') The documnetation is updated to mention @managed.
