[Users] High Availability OVirt
Is there any way to create redundancy oVirt-engine? We install oVirt-engine in a machine, and what happens if that burning machine? Is there anything that can be done to remedy this? Att, -- “Encarada do ponto de vista da juventude, a vida parece um futuro indefinidamente longo, ao passo que, na velhice, ela parece um passado deveras curto. Assim, a vida no seu início se apresenta do mesmo modo que as coisas quando as olhamos através de um binóculo usado ao contrário; mas, ao seu final, ela se parece com as coisas tal qual são vistas quando o binóculo é usado de modo normal. Um homem precisa ter envelhecido e vivido bastante para perceber como a vida é curta”. (Poema de Arthur Schopenhauer)
Hi, You can use a cluster software like pacemaker or RH Cluster to make your ovirt-engine high available. I personally recommend to virtualise it on a KVM host, as keeping virtual machines high available is much easier then making all services ovirt-engine need high available (but it's possible for sure). So what happens when your engine hosts goes down: - You can't login into webadmin and user portals - high availability and live migration features of your virtual machines aren't working - You can't start/deploy new virtual machines - Your hosts and virtual machines that are already running stay up of course As clustering brings in more complexity I would use a server with RAID, redundant power supplies and redundant network interfaces (bonding) for ovirt-engine instead of clustering. Only when using desktop virtualization where availabilty of the user portal is really important I would cluster ovirt-engine. (But this is just my personal opinion) Regards, René On Fri, 2013-04-19 at 08:19 -0300, victor nunes wrote:

and we're looking at a hosted engine which will try to solve this "out of the box".
