Ovirt devel - Jul 2009 - poweroff in vm causes the host to become unavailable

If  I ssh to a vm running Centos and then execute "poweroff" from
within
the vm, the vm shuts down as expected but the host in the admin ui 
becomes unavailable.  Is anyone else experiencing this?  I haven't 
checked to see if other guest OS's do the same thing yet.

The painful thing is that then I have to shutdown all the VMs and reboot 
both the host and the management server in order to be able to manage 
the system again.  I'm also still having problems with storage not 
working.  On reboot if I start a VM that was working it complains that 
it can't find the storage.  The only way I've been able to fix this is 
to delete all the VMs, delete all the attached storage then add the 
storage and VM again, a little painful.

Cheers,
Justin.

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!
