Now I have made more tests: The user has write permissions to existing files, but cannot create new files on the guest (it's possible on the host) > Could you send the output of: > 'ls -lnd /mnt/xyz/123' > (both in the host and the guest) > > and also the output of 'id' in the guest (with the user you are trying to > write)
ls -lnd /mnt/xyz/123 -rw-r--r-- 1 16009 16100 0 Apr 4 19:32 /mnt/xyz/123id 16009gid=16000, groups=...,16100(...),...
