Well, till now, no virtulization vendor can provide truly 0% downtime product, even vmware's FT&DRS or Citrix's Xenmotion or MS's Live migration, there will be nearly 1 or more seconds the client will lose connection to the virtual server. From the migration's theory(memory copy), we can know there won't be 0% downtime. I haven't tested RHEV, but I've tested Redhat Xen live migration, there's also a short pause, so I don't think the RHEV can provide 0% downtime neither.

Does RHEL Cluster can provide 0% of downtime, means I need "zero downtime" cause my application needs to always available on any condition, even 1 minutes off. Maybe you can give me some documentation? And, could you please to tell me, how can I create RHEV to fail over condition? Thanks in advance for your help.
