Re: [Xen-users] Xen clustering

Hi.
I'm writing to the mailing list to know if Xen is what I'm looking for.
I need a failover cluster with two completely and automatically
replicated and redundanced servers running Windows Server 2003
Standard.
Could Xen make this?
Where I can found some information about making this configuration with Xen?
Thank you very much for your help!
Bye.
Not..... exactly. You can keep multiple operating systems on a single
server: you can migrate them from a common network storage to run on one
server or another. But failover where one server's operating system
fails or is disabled, and another takes over the function, is a much
more interesting thing to do. To do complete OS failover, every physical
component must be mirrored and matched and the connections duplicated
with failover redundancy, and that gets fascinating to support. It's
also amazingly expensive, much more than the cost of a small set of
duplicate servers.
If you have specific services running on those servers, you might be
able to gracefully implement them in normal master/slave or
master/master failover modes.
