当我尝试启动 VM 时，出现以下错误（注意，主机是 OpenSUSE Leap 15.3）：

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 75, in cb_wrapper
    callback(asyncjob, *args, **kwargs)
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 111, in tmpcb
    callback(*args, **kwargs)
  File "/usr/share/virt-manager/virtManager/object/libvirtobject.py", line 66, in newfn
    ret = fn(self, *args, **kwargs)
  File "/usr/share/virt-manager/virtManager/object/domain.py", line 1281, in startup
    self._backend.create()
  File "/usr/lib64/python3.6/site-packages/libvirt.py", line 1234, in create
    if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)
libvirt.libvirtError: Internet Error: qemu unexpectedly closed the monitor: 2022-04-13T10:23:46.817809Z qemu-system-x86_64: -device virtio-9p-pci,id=fs0,fsdev=fsdev-fs0,mount_tag=/home/turbine,bus=pci.7,addr=0x0: cannot initialize fsdev 'fsdev-fs0': failed to open '/home/user/shared': Permission denied

我的共享文件夹配置给了我：

<filesystem type="mount" accessmode="passthrough">
  <driver type="path" wrpolicy="immediate"/>
  <source dir="/home/user/shared"/>
  <target dir="/shared"/>
  <address type="pci" domain="0x0000" bus="0x07" slot="0x00" function="0x0"/>
</filesystem>

答案1

结果是，该目录必须位于每个目录的路径中，然后才能由任何用户读取和搜索。
