That depends solely on the kind of hardware you use. We've pulled over 1.5 million IOPS with a single KVM instance 4 years ago, I'm sure mysql and rrd require much less.

Or that, but virtualization is not a great solution for a heavily loaded observium installation.

You seem to be trying terribly hard to vastly overcomplicate your deployment.
You can certainly run two installations (though that would require two licenses), but they won't communicate in any way, since we don't have any form of replication.
I'd be inclined to just rsync RRDs and copy the database and config periodically to a second server, so you can switch over to a second system if the first one explodes. You'll lose data between the most recent backup and the system failure, but you'll gain not having to spend the £20,000 we'd be charging if we supported full active/active replication.
I don't consider metric collection and monitoring to be a business critical service, so doesn't really require replication and failover. Even losing a few hours of billing data isn't really an issue.
Just have a decent backup/restore procedure and you that's sufficient.
It's also true that a decent backup policy is far safer than relying on active replication, since a software or configuration issue will destroy both of your instances. Just ask people who've run VSS!

No. And since it only takes 15 minutes to install a new system, we're not convinced that the massive increase in complexity (and network load) would be a good idea.
Observium is literally config.php, a MySQL database and a directory of RRDs. Complex stuff isn't really needed, nor particularly helpful.
Just make periodic backups and make sure you know how to restore the MySQL database and RRD directory on failure.
