Não é possível iniciar o domínio depois de adicionar o diretório compartilhado do Filesystem Fedora 27

Question

Eu criei um guest fedora 27 no meu host fedora 27, adicionei 2 compartilhamentos do Filesystem, adicionei entradas no fstab guest / s, inicializei e tudo funciona bem. No entanto, quando eu tento adicionar outra unidade / montagem do host, "d_drive", recebo o seguinte erro e não sei como solucionar o problema. Tanto quanto eu posso dizer os compartilhamentos de trabalho têm a mesma propriedade de usuário e permissões que o d_drive problemático, e de um simples "getfacl", parece que essas permissões são quase iguais, menos as flags (que eu não entendo) ).

Onde / como eu começo a solucionar isso?

informações do sistema:

Esta pode não ser a totalidade dela, mas parece funcionar (aparentemente eu já tive o primeiro comando ...).
