Debian 10 머신에 Windows 10을 실행하는 KVM 가상 머신이 있습니다. 잘 작동합니다. libvirt 버전은 5.0.0-4+deb10u1입니다.
USB를 통해 Debian 호스트에 연결된 카메라를 가상 머신이 인식하도록 하고 싶습니다. XML 파일에 다음 코드를 추가하면 실패합니다.
<hostdev mode='subsystem' type='usb'>
<source startupPolicy='optional' guestReset='off'>
<vendor id='0x04da'/>
<product id='0x2497'/>
</source>
</hostdev>
에러 메시지:
error: XML document failed to validate against schema: Unable to validate doc against /usr/share/libvirt/schemas/domain.rng
Extra element devices in interleave

끝부분에 문제가 되는 코드를 포함한 전체 XML 파일은 다음과 같습니다. 코드는 단어 그대로입니다.libvirt 문서.
어떻게 되어가나요? "엇갈려"은(는) 무슨 뜻인가요? 더 많은 통찰력을 제공하기 위해 XML 파일을 검사하는 다른 방법이 있습니까?

답변1
libvirt 문서에는 다음과 같이 명시되어 있습니다.
8.6.0부터 소스 요소에는 다음 값을 가진 guestReset 속성이 포함될 수 있습니다.
Libvirt 5를 사용하고 있으므로 guestReset
이 속성은 지원되지 않습니다. 이를 제거한 후 XML 파일은 유효성 검사를 통과합니다.
오류 메시지가 좀 더 설명적이면 좋을 것 같습니다.
