OpenSolaris guest; can't delete from shared folder

[lefevrol]

I mounted the shared folder under /mnt/share and while I can read from and write to it from within the VM I cannot delete anything: I always get "Invalid argument"; all the files have permission 777. What is causing this behaviour? Thanks.

There are separate permissions for the share. They are applied over the actual permissions of the directory in the filesystem. So the directories permissions on your computer represent he most lenient permissions possible, however when you create the share you can limit them further (but not reduce them).
