Errors on 9p mounts
Description of problem:
I'm trying to run Docker VMs with [Lima](https://github.com/lima-vm/lima), which uses QEMU. I'm trying to expose my home directory on macOS to the Ubuntu VM using `9p`. This is how the mount point looks like inside the Ubuntu VM:
```
root@lima-docker:~# mount | grep Users
mount0 on /Users/carlos type 9p (rw,relatime,dirsync,fscache,cachetag=4294894070,access=user,trans=virtio,version=9p2000.u)
root@lima-docker:~#
```
The problem I'm seeing is that doing an `ls -l /Users/carlos` gives a "Timer expired" error, and no output:
```
root@lima-docker:~# ls -l /Users/carlos
ls: reading directory '/Users/carlos': Timer expired
total 0
```
Under `strace`, it seems that the timer error is raised by the `getdents64` system call:
```
root@lima-docker:~# strace -f ls -l /Users/carlos
[..]
openat(AT_FDCWD, "/Users/carlos", O_RDONLY|O_NONBLOCK|O_CLOEXEC|O_DIRECTORY) = 3
newfstatat(3, "", {st_mode=S_IFDIR|0755, st_size=1984, ...}, AT_EMPTY_PATH) = 0
mmap(NULL, 135168, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xffffa16bf000
getdents64(3, 0xffffa16bf040, 131072) = -1 ETIME (Timer expired)
[..]
```
I've also tried the `9p2000.L` protocol instead, and the results are a bit better. I do get a directory listing, but I see "xxx" errors:
```
root@lima-docker:~# ls -l /Users/carlos
ls: /Users/carlos: Network dropped connection on reset
ls: /Users/carlos/Music: Network dropped connection on reset
ls: /Users/carlos/Pictures: Network dropped connection on reset
ls: /Users/carlos/Desktop: Network dropped connection on reset
ls: /Users/carlos/Library: Network dropped connection on reset
ls: /Users/carlos/Public: Network dropped connection on reset
ls: /Users/carlos/Movies: Network dropped connection on reset
ls: /Users/carlos/Applications: Network dropped connection on reset
ls: /Users/carlos/Dropbox: Network dropped connection on reset
ls: /Users/carlos/Maildir: Network dropped connection on reset
ls: /Users/carlos/Documents: Network dropped connection on reset
ls: /Users/carlos/Downloads: Network dropped connection on reset
total 0

```
The errors in this case seem to come from the `lgetxattr`system call:
```
root@lima-docker:~# strace -f ls -l /Users/carlos
[..]
statx(AT_FDCWD, "/Users/carlos/Downloads", AT_STATX_SYNC_AS_STAT|AT_SYMLINK_NOFOLLOW, STATX_MODE|STATX_NLINK|STATX_UID|STATX_GID|STATX_MTIME|STATX_SIZE, {stx_mask=STATX_BASIC_STATS|STATX_MNT_ID, stx_attributes=0, stx_mode=S_IFDIR|0700, stx_size=5248, ...}) = 0
lgetxattr("/Users/carlos/Downloads", "security.selinux", 0xaaaaec72da70, 255) = -1 ENETRESET (Network dropped connection on reset)
write(2, "ls: ", 4ls: ) = 4
write(2, "/Users/carlos/Downloads", 23/Users/carlos/Downloads) = 23
write(2, ": Network dropped connection on "..., 37: Network dropped connection on reset) = 37
[..]
```
I've reported this to the Lima folks at https://github.com/lima-vm/lima/issues/831, and they suggested opening an issue here. Any ideas?
Steps to reproduce:
1. If you have Lima installed (I'm using version 0.10.0): `limactl start --name=docker ./lima-templates/docker.yaml`
