If your job is to monitor hosts in realtime, there are already really good 
monitoring solutions for this.  I don't think we are attempting to replace 
NOC software with oVirt.  We're trying to handle things like managing 
virtual systems, provisioning and simplifying the usage of the datacenter.

If you need to look at performance trends to determine whether or not to 
rebalance your vms across physical hosts, oVirt will be able to do that 
for you.  If you're looking to divvy up hardware among different groups in 
your organization, we'll do that too.

If you're looking to monitor hosts and get immediate notification of when 
they go down, then you probably already have a system implemented in your 
NOC that does this.  (I can think of a few big names offhand)  Maybe 
eventually we can have oVirt try to get into this space, but I think doing 
that right now might be a bit premature.  We need to get really good at 
the other things I mention above.  (i.e. our core capabilities)
