Shared Folders issue with OS X VM on ESXi 5.1

I've got an OS X guest VM running on ESXi 5.1, running on an Xserve.

When I execute an "ls -l /Volumes" command, I get:

ls -l /Volumes/

ls: VMware Shared Folders: Input/output error

total 8

lrwxr-xr-x  1 root  admin  1 Jun 20 06:03 OSX -> /

Obviously, there are some remnants of Shared Folders that are causing this problem.  I have noticed when I log into the desktop on an OS X VM, the Shared Folders directory shows up for a second, then disappears.

So, does anyone know how to permanently disable the Shared Folders function of VMWare Tools somehow?  There's no switch for it in ESXi, as I believe ESXi doesn't support it.

Thanks for any help!
