Running the server(s) in a VMware setup?

[edge]

I'm about to install a new server, and I was thinking of putting this all in a VMware setup.

Basically it will be a Debian Etch system** running a Debian Etch server within VMware.
The Debian Etch running in VMware will be running all the needed server stuff (ISPconfig / DNS / Mail / Apache / ....).
**The server (hardware) will be a Dual Xeon system with about 8GB of memory.

Reason for doing things this way is to make it much easier to recover from crashed systems. (I can take a snapshot of the system every day), and that the main system will (should) never hang!

My question now is, if I am not making things to complicated this way?

Any feedback on this appreciated!
