Hi, I am trying to setup a cluster of two nodes, with self hoste Engine=
. Things went fine for the first machine, but it as rather messy about t=
he second one. I would like to have load balancing and failover for both=
management network and storage (NFS repository). So what should I exa=
ctly do to get a working network stack which can be recognized when I tr=
y to add this host to the cluster ? Have tried configuring bonds and b=
riges using Cockpit, using manual "ifcfg" files, but all the time I see=
the bridges and the bonds not linked in the Engine interface, so the ne=
w host cannot be enrolled. If I try to link "ovirtmgmt" to the the assoc=
iated bond, I have a connectivity loss because it is the management devi=
ce, and I have te restart the network services. As management configurat=
ion is not OK, I can't setup the storage connection. And if I just try=
to activate the host, I will install and configure things and then comp=
lain about missing "ovirtmgmt" and "nfs" networks, which both exist
and=
work and Centos level. The interface, bonds and bridge names are copy=
/paste from the first server. # brctl show ovirtmgmt=0Abridge name bri=
