Hi Wahyu, Under my Gigabit ethernet, it may take 10secs or 1/2mins to migrate(depends on the vm's memory),and the down time is very short---using "ping" to the vm may lose only one packet, however, to use migration, you don't need RHCS, what you need is shared storage.

Can you share how many time did you need to use Redhat Xen live migration, is it failover? Have you tested for RHEL Cluster failover condition, how many time RHEL Cluster can handles the failed node to switch another one? I need this info to assess my application. Thank you all for your cooperation.

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.
