Re: [ovirt-users] Best practices for LACP bonds on oVirt

Thanks, Konstantin. Just to be clear enough: the first deployment would be made on classic eth interfaces and later after the deployment of Hosted Engine I can convert the "ovirtmgmt" network to a LACP Bond, right? Another question: what about iSCSI Multipath on Self Hosted Engine? I've looked

Hello, I’m deploying oVirt for the first time and a question has emerged: what is the good practice to enable LACP on oVirt Node? Should I create 802.3ad bond during the oVirt Node installation in Anaconda, or it should be done in a posterior moment inside the Hosted Engine manager? In my

Note we do not support 7.0 anymore. oVirt 4.1 needs 7.3, master/nightly would require 7.4 as soon as it is released The ISO I had was CentOS 7.0 (whoops), I'll go upgrade it ASAP! Thanks. But as Oved says, there’ s not much sense in trying to use/compile UserPortal on current nightly
