[Xen-users] Xen implementation design issue

["Devraj Mukherjee" <devraj@xxxxxxxxx>]

Hi Everyone,

I am very new to Xen and am hoping to deploy a solution based on
CentOS or OpenSUSE. We are a looking at using Xen to create warm
spares for servers we run for our Internet infrastructure.

Here is what we plan to do with our Xen enabled setup.

Two physical servers each running two Xen virutal servers one acting
as the corporate web server and the other as a email server

The first physical machine will be the primary server web server but
the backup (warm spare) mail server and the second machine will be
primary mail server but backup (warm spare) web server.

Each spare is going to be Rsync data from the production image (virtual server).

As a newbie I'd like some direction if this is a good strategy for
creating warm spares? And if yes can I facilitate this using Xen so
that the warm spare takes over incase the production virtual server
fails?

Thanks for your time and any pointers.

Devraj
