Running something like the above with samba installed should spin up `smbd`= ; however, this doesn't happen. I see no smbd processes started. Qemu does cr= eate /tmp/qemu-smb.XXXXXX/smb.conf, however. Am I just missing something obvious? Can your reproduce? Digging through the qemu repo[0], it looks like qemu calls out to a samba daemon with an invocation that resolves to this: $ smbd -l /tmp/qemu-smb.XXXXXX -s /tmp/qemu-smb.XXXXXXX/smb.conf Manually running the above results in silent failure, though. To be clear, running the above with --foreground makes no difference. For good measure, I am attaching the smb.conf that qemu generates, in case = you want to directly try the smbd command without spinning up qemu. Note, you m= ay need to edit the 'path=3D/shared' line to an existing directory on your mac= hine. Throwing strace at the above shows that the daemon is getting EPERM when tr= ying to bind() the priviledged ports 445 and 139. Indeed, running the daemon under sudo works as expected, and I am able to access the shared directory from the guest machine as intended. Given the permission issues, I did try adding /sbin/smbd to my setuid-programs= , but that seems to make no difference. Is this a PEBKAC issue or a legitimate bug?

Running something like the above with samba installed should spin up `smbd`= ; however, this doesn't happen. I see no smbd processes started. Qemu does cr= eate /tmp/qemu-smb.XXXXXX/smb.conf, however. Am I just missing something obvious? Can your reproduce? Digging through the qemu repo[0], it looks like qemu calls out to a samba daemon with an invocation that resolves to this: $ smbd -l /tmp/qemu-smb.XXXXXX -s /tmp/qemu-smb.XXXXXXX/smb.conf Manually running the above results in silent failure, though. To be clear, running the above with --foreground makes no difference. For good measure, I am attaching the smb.conf that qemu generates, in case = you want to directly try the smbd command without spinning up qemu. Note, you m= ay need to edit the 'path=3D/shared' line to an existing directory on your mac= hine. Throwing strace at the above shows that the daemon is getting EPERM when tr= ying to bind() the priviledged ports 445 and 139. Indeed, running the daemon under sudo works as expected, and I am able to access the shared directory from the guest machine as intended. Given the permission issues, I did try adding /sbin/smbd to my setuid-programs= , but that seems to make no difference. Is this a PEBKAC issue or a legitimate bug?
