Depending on the bandwidth/latency between the locations you could go for
replicated GlusterFS strorage and make sure that data is replicated accross
both sites. There is a self-hosted engine feature coming up, I don't know how
that will fit into replication.

Hello,
I am evaluating oVirt as a replacement/alternative to VMware deployments we

another point is, that a correct configured multipathing is way more solid

the short way of getting the correct certificate to connect to the
