Ubuntu - Virtual Host pointing to Folder on host machine (Mac)

[GherardoC]

Hello everyone,
I have successfully installed Ubuntu, made it a functioning LAMP and set up a test virtual host.
Now I would like to create another virtual host that points to a folder that is not on the virtual HD created by Parallels to host Ubuntu, but that is on the main os, Snow Leopard.
I have tried to do so by setting the virtual host like so:

<VirtualHost *:80>
DocumentRoot /home/parallels/Desktop/ParallelsSharedFolders/Home/Sites
etc.

(I have renamed `Parallels Shared Folders` to `ParallelsSharedFolders` to remove the spaces)

but apache tells me:

* Reloading web server config apache2 /usr/sbin/apache2ctl: 87: ulimit: error setting limit (Operation not permitted)
Warning: DocumentRoot [/home/parallels/Desktop/ParallelsSharedFolders/Home/Sites/Enoron] does not exist

Is it anyhow possible to achieve what I'm trying to do?
