One of my customers has requested that their web server is encrypted to prevent offline attacks to highly sensitive data contained in a mysql database and also /var/log. I have full root access to the dedicated server at a popular host. I am considering 3 options -

FDE - This would be ideal, but with only remote access (no console) I imagine this would be very complex.
Xen - installing XEN and moving their server within a XEN virtual machine and encrypting the VM - which seems easier to do remotely.
Parition - encrypt the non-static partitions where the sensitive data resides e.g. /var /home etc.

What would be the simplist approach that satisfies the requirements?
