[Ovirt-devel] problem with kerberos (I think)

Hi again,
I have two questions:

1. In order to make my node working (the node where I've installed ovirt appliance), I need to regularly do a kinit. Is it normal?
2. Other question, When I try to add a storage pool, I have the following error:

INFO Mon Aug 03 10:43:27 +0200 2009 (7407) Connecting to amqp://management.open.net:5672

I took a look at the code and the problem seems to be here (in taskomatic.rb, line 582):
    573   def storage_find_suitable_host(hardware_pool)
    574     # find all of the hosts in the same pool as the storage
    575     hardware_pool.hosts.each do |host|
    576       @logger.info "storage_find_suitable_host: host #{host.hostname} uuid #{host.uuid}"
    577       @logger.info "host.is_disabled is #{host.is_disabled}"
    578       if host.is_disabled.to_i != 0
    579         @logger.info "host #{host.hostname} is disabled"
    580         next
    581       end
--> 582       node = @session.object(:class => 'node', 'hostname' => host.hostname)
    583       @logger.info "node: #{node.inspect}" if node
    584       return node if node
    585     end

But when I do a qmf-libvirt-example, I have the host and it seems OK:
[root at management ~]# ruby /usr/share/ovirt-server/qmf-libvirt-example.rb

Any ideas?

I also think this problem was a qpid problem.
I still have issues with node authentification though

Looks like my problem is the same...

I had a running system which failed after running a yum update.  From 
memory there were qpid and qmf updates.

Taskomatic seems to stay up once restarted though.
