Wrong user and group in shared folders (Parallels 7 on OS X)

[matrikz]

Hi,

I just converted a Linux virtual machine from VMware to Parallels 7. I have three shared folders from my OS X (Lion) host system linked into the vm.

The guest system is a Debian unstable. The Parallel Tools installed fine and as far as I can see, everything works flawlessly. But I have one strange problem I couldn't solve yet.

The uid and gid of the shared folders are very strange.

my /media/psf looks like this:

drwxr-xr-x 1 thomas www-data 0 Sep 25 09:05 .
drwxr-xr-x 5 root root 4096 Sep 24 21:20 ..
drwx------ 1 thomas www-data 1462 Sep 24 21:43 Home
dr-xr-xr-x 1 4294967295 4294967295 1224 Sep 24 19:21 Host
drwxr-xr-x 1 thomas 4294967295 408 Sep 24 19:12 instances
drwxrwxr-x 1 thomas 4294967295 1190 Sep 17 08:00 logs
drwxrwxr-x 1 thomas 4294967295 476 Aug 29 20:23 sources

As you can see, the gid is really weird. I tried to set it manually in fstab but it seems to be ignored for shared folders. The /media/psf get's the correct user and group though.

My fstab looks like this:

#Parallels Shared Folder mount
none /media/psf prl_fs defaults,exec,user,exec,uid=501,gid=33 0 0

uid is user "thomas" and gid is my "www-data" group. I already tried to change the gid on the host side, but that had no effect at all. The user group is always this ridiculous large number.

Is there a working solution to set the gid for the shares?

Thanks,
Thomas
