    If the oVirt manager (ie. the web application running inside AS7)
    loses connectivity to the node, the VM's on that node will keep
    running.&nbsp; You should know; however, that the general design is for
    the manager to remain in contact with the nodes. <br>

    It depends on what you are trying to do.&nbsp; oVirt and virt-manager
    solve different problems.&nbsp; I would say that virt-manager is probably
    OK for a small setup, but I wouldn't deploy an enterprise solution

    You have enough gear for a small oVirt setup.&nbsp; Run with that and add

            (ie. ovirt-node) and a third machine that can be a dedicated

            <br>
            If the former then one machine must run some version of *nix

            Generally, speaking.&nbsp; Yes.<br>
            <br>
            Truly HA setups aren't cheap and people often have different
            ideas of what constitutes HA.&nbsp; Offhand I would think that
            you would need...<br>
            <br>
            - 2 boxes for the oVirt manager<br>
            - Clustering software for the manager to facilitate an
            active/passive setup.<br>
            - UPSs (at *least* 2) which can be controlled by clustering
            software.&nbsp; Why?&nbsp; Most clustering SW require a fence device.&nbsp;
            These will be your fence devices.<br>
            - 2 boxes for your hypervisors (ie. ovirt-nodes).&nbsp; This will
            facilitate fail-over from one node to the other.<br>
            <br>
            HA isn't cheap and can't usually be done on 2 boxes, IMO
            unless you're failing over a single app.

                        Huh?&nbsp; You could run the oVirt Manager from a VM

                        oVirt manager inside a VM on a hypervisor (ie.
                        ovirt-node) controlled by that same manager
                        isn't supported AFAIK because the mgr. could get
                        fenced.&nbsp; <br>
                        <br>
                        To summarize, you can pretty much run the oVirt
                        manager on any supported OS as long as that OS
                        instance isn't running on a hypervisor (ie.
