We have been using oVirt for over 3 years. When we first setup= oVirt environment, Hosted Engine componment did not exist. Our question i= s should we migrate our current configuration to use Hosted Engine? First let me give an overview of our configuration. We have blade servers = in 2 separate racks. D1 & X1. Each side has 10 blades. Storage is iSCSI = SAN. Inside our oVirt 3.5.0.1-1.el6 installation, it is configured with 2 data c= enters. D1 & X1. Each datacenter has the 10 blades for that side. The ma= nagement function of oVirt (oVirt web console) is running off 2 VMs, ovirt-= mgmt-1 on D1, and ovirt-mgmt-2 on X1. We have keepalived to maintain a flo= wing IP for the oVirt management console. The keepalived script makes sure= only one copy of ovirt-engine is running at any time. It can be on D1 or = X1. The mgmt VMs have Postgresql setup in replication mode. In case one o= f the mgmt vm failed, the other mgmt vm on the other rack can pick up the m= gmt role. Both mgmt VMs can see all blades and SAN resources on D1 & X1. This configuration has been working well for us. The drawback is if both o= virt mgmt vm crashed, we will not be able to start them or make any change = to the ovirt environment. It is because the mgmt VMs are running within th= e oVirt domain. We tried to upgrade our configuration to Hosted Engine configuration. From= what I understand, the Hosted Engine will run in a separate storage domain= . In both times we tried to upgrade to Hosted Engine, they both failed dur= ing export and import of current configuration. I think my questions are: - will the Hosted Engine model works in our hardware configuration. With h= ardware in 2 racks, D1 & X1. Can a single Hosted Engine manage hardware on= both sides? - How can we achieve redundancy when running Hosted Engine? We need to hav= e management capibility in case one side completely failed. Thanks in advance.
