we need to have a failover linux sever for our current linux server(physical server running redhat ent 5.4) that runs Drupal and Apache.  We have several drupal sites on this server.
The failover server would be a vm.  Does this server have to be built form ground up or can one image a linux (physical server)?  Thank you,.

    You could considering Clustering, at the Linux VM, or you could use VMware HA or VMware FT.

    If the VM is vmware you could use VMWare Converter for linux and create a virtual machine from the physical machine.  After you create the virtual machine you could use rsync and mysql tools to synchronize your drupal and apache system.  Mysql has several documents on how create a master and replicated database.  The rest could be done just by using rsync and cron to keep files the same between the servers.

    Double Take HA is another software application which can replicate in real time
