Hi Carlos,

Before anything else, sorry for the delay in my answer.I have been very 
busy this past month and I haven't been able to test the patch that you 
prepared to solve the monitoring problem.

Finally last week I tested the patch but the monitoring problems 
continue although the machines no longer happen to unknown state. I have 
executed from line of commands but the messages are the same that they 
appear registered in logs.

[oneadmin at dn07 ~]$ /var/tmp/one/vmm/xen/poll one-28
Error executing sudo /usr/sbin/xentop -bi2
/var/tmp/one/vmm/xen/poll:186:in `get_vm_info': undefined method `[]' 
for nil:NilClass (NoMethodError)
         from /var/tmp/one/vmm/xen/poll:314:in `print_one_vm_info'
         from /var/tmp/one/vmm/xen/poll:348


Can you think of any other thing that I could test?

Thank you very much in advance.
BR,

     María
