Hello there,

I have a questions about the Redhat Virtualization which we plan to install in our production environment, at first our planned is to have RedhatCluster Suite for setting up high availability since the redhatserver we plan to install will host PostgreSQL database.

But since I'm reading RedhatVirtualization is support HighAvalaibility, My thoughts this can be another way of provide failover support.

So my questions is, can this RedhatVirtualization support HighAvalability as per redhatCluster Suite is providing ?

Look into pgpool-II(use unsigned CentOS 6 RPM for RHEL or build and sign your own)

From your question, I was not sure how you wanted to set up the systems. However, both of the following are supported:

(1) Run the Red Hat HA cluster on RHEV-M
The following is a summary of the virtual hosts that Red Hat supports for virtual machines in a HA cluster, which includes several versions of RHEV-M:

(2) Run RHEV-M as the highly-available service on a Red Hat HA cluster
See the following technical review that covers how to run RHEV-M in a high-availability cluster:
