[one-users] help with a configuration

[Jan M. Stankovsky]

I have a single server with access to a SAN System. I would like to use
this server as a (cluster) node [host] and virtualize the frontend on my
working place computer with virtualbox. I don't want to share anything
between the host and the frontend but i can mount filesystems from the
host to the frontend on demand.
in such a setup where/how should i put the image repositories, because
the host has the storage.

thanks
