Hi,<br>
<br>
You can use a cluster software like pacemaker or RH Cluster to make your<br>
ovirt-engine high available.<br>
<br>
I personally recommend to virtualise it on a KVM host, as keeping<br>
virtual machines high available is much easier then making all services<br>
ovirt-engine need high available (but it's possible for sure).<br>
<br>
So what happens when your engine hosts goes down:<br>
- You can't login into webadmin and user portals<br>
- high availability and live migration features of your virtual machines<br>
aren't working<br>
- You can't start/deploy new virtual machines<br>
- Your hosts and virtual machines that are already running stay up of<br>
course<br>
<br>
As clustering brings in more complexity I would use a server with RAID,<br>
redundant power supplies and redundant network interfaces (bonding) for<br>
ovirt-engine instead of clustering. Only when using desktop<br>
virtualization where availabilty of the user portal is really important<br>
I would cluster ovirt-engine.<br>
(But this is just my personal opinion)<br>

and we're looking at a hosted engine which will try to solve this "out of the box".<div class="HOEnZb"><div class="h5"><br>

Is there any way to create redundancy oVirt-engine?<br>
We install oVirt-engine in a machine, and what happens if that burning<br>
machine?<br>
<br>
<br>
Is there anything that can be done to remedy this?<br>
