Re: HA for Xen

["John R. Shannon" <john.r.shannon%us.army.mil@localhost>]

I have a pair of dual-redundant servers running Xen with several guest 
domains. Each guest domain has a carp interface with the same IP. Only 
one will respond to an arp request at a time (the carp protocol 
determines which). Failover is automatic.

Application data is dealt with according to the application. dbmail with 
a mysql database is used for an imap server so that mysql's redundancy 
mechanism can be used. A periodic rsync takes care of other apps like 
the web server pages.
