Which version are you running?

There has definitely been issues with QMF not behaving properly in terms
of updating objects etc.  I've had a hard time tracking this down to
something specific however.  This is consistent and reproduceable?

The host becomes unreachable when the QMF libvirt object representing the
host is not available or the agent backing that object stops sending 
heartbeats.

Can you run:

# ruby /usr/share/ovirt-server/qmf-libvirt-example.rb

And see if the host object in question shows up?  This program just lists
all hosts, vms, storage pools etc. that it can find every 5 seconds, so it
will print lots of output if left running.  Iterations are separated by a
line of dashes; eg '-----'.

Thanks!
